Monsoon season is officially underway. In addition to dust storms, the monsoon brings the potential for sudden, intense downpours.

Now is the time to get rainstorm-ready. Here are some suggestions for prepping your vehicle:

  • Check your tire pressure and tire treads. You don’t want to be caught on slippery road surfaces with poorly inflated or bare tires.
  • Check your windshield wipers. Blades can quickly wear, crack or become rigid. Their average lifespan is six months to a one year. You don’t want to discover during a deluge that they aren’t up to the task. Also, top off your windshield washer fluid.
  • Clean and check your vehicle's battery. Remove corrosion and ensure cables are securely attached to terminals. We live in a state where batteries tend to last about two years. You don’t want to get caught in driving rain when your battery dies.

Now that your vehicle is shipshape, you need to pack supplies. Bring extra water, an emergency kit, a fully charged cellphone, hand sanitizer, wipes and a cloth face mask. Snacks and extra clothes can be handy if you are in a rain-related backup.

Are you ready for the road? Expect the unexpected. Are you in area prone to falling rocks? Stay alert because rain can loosen them. Are you driving into heavy rain, like this photo to the right from several years ago? Consider delaying travel or waiting it out in a safe spot as far off the road as possible.

Do you know what to do if your vehicle hydroplanes? This is when you drift due to a thin layer of water between your tires and the asphalt. Ease your foot off the gas pedal until you regain traction. Don't brake suddenly. If you are sliding or drifting, gently turn your steering wheel in the direction of your slide.

Even if you're not hydroplaning, don’t brake suddenly or you could slide on wet pavement. Leave plenty of room between your vehicle and the one ahead of you. To slow down on a wet road, take your foot off the gas pedal and brake slowly.

It may seem like common sense, but do not risk crossing a flooded wash, even it if doesn’t seem deep. Water is a powerful force, as you can see in the photo of past flooding, and you could be swept away. Also, do not drive around “Road Closed” signs. Your risk your life and face being cited under the state’s Stupid Motorist law.

PHOENIX – The official start of monsoon season is here and Arizonans know what to expect in the coming months: occasional dust storms and torrential rain.

As the Arizona Department of Transportation marks Monsoon Awareness Week (June 14-20) with reminders to “Pull Aside, Stay Alive” when drivers encounter blowing dust, ADOT is also providing information about the first-of-its-kind dust detection system on a stretch of Interstate 10 between Phoenix and Tucson.

Motorists traveling through this 10-mile stretch of I-10 near Picacho Peak (between mileposts 209-219), an area prone to sudden blowing dust, will see weather radar, overhead message boards and variable speed limit signs. Here’s what travelers should know:

  • As drivers enter the detection zone they will see signs alerting them that they’ve entered a variable speed corridor.
  • When the system detects reduced visibility because of dust, variable speed limit signs, which are placed every 1,000 feet near the entrance of the corridor, can change the legal speed limit from 75 mph to as low as 35 mph. Additional variable speed limit signs are placed every 2 miles.
  • The system will also automatically activate overhead message boards with a warning for drivers to slow down when visibility drops because of windblown dust.
  • If visibility is clear, drivers will notice no change.

It’s important to note that this pilot-project technology exists only at this location -- dust storms can occur anywhere in Arizona – and doesn’t replace common sense. When you see a dust storm, do not drive into it. If you get caught in a fast-moving dust channel, follow the “Pull Aside, Stay Alive” tips to help survive a blowing dust event.

  • If you encounter a dust storm, immediately check traffic around your vehicle (front, back and to the side) and begin slowing down.
  • Do not wait until poor visibility makes it difficult to safely pull off the roadway – do it as soon as possible. Completely exit the highway if you can.
  • Do not stop in a travel lane or in the emergency lane. Look for a safe place to pull completely off the paved portion of the roadway.
  • Turn off all vehicle lights. You do not want other vehicles, approaching from behind, to use your lights as a guide and possibly crash into your parked vehicle.
  • Set your emergency brake and take your foot off the brake.
  • Stay in the vehicle with your seat belt buckled and wait for the storm to pass.
  • Drivers of high-profile vehicles should be especially aware of changing weather conditions and reduce speeds.

PHOENIX ‒ Keep an eye on the forecast and be ready to slow down with heavy rain possible early next week.

If tropical moisture enters the state, the Arizona Department of Transportation’s safety tips include turning on headlights while driving in threatening weather and, when roads are wet, reducing speed and maintaining a safe distance between your vehicle and the one ahead.

Avoid areas where water is pooling in travel lanes. If your vehicle appears to be hydroplaning, ease your foot off the gas pedal until you regain traction rather than braking suddenly, which can cause a vehicle to skid. Be aware that the tires of larger vehicles can create spray that reduces visibility for those following too closely.

When traveling away from freeways, don’t risk crossing a flooded wash, even if it doesn’t look deep. Just a few inches of running water can carry away a vehicle, even a heavy pickup truck or SUV. Driving around “Road Closed” signs puts your life at risk and could get you cited under the state’s "stupid motorist" law.

Before a storm, it’s always wise to inspect windshield wipers and replace them if necessary.

They say lightning never strikes the same place twice. And that's why we're glad a bolt that streaked boldly from the northeastern Arizona sky last Sunday wound up immortalized by a 511 camera and then by ADOT's social media accounts.

This improbable photographic feat was courtesy of a Road Weather Information System camera along State Route 77 roughly 10 miles south of Holbrook. Before you start doubting the unique nature of this event, consider:

• RIGHT PLACE: These cameras in rural areas of Arizona are mounted on elevated surfaces such as light poles and record the same view over and over.

• RIGHT TIME: This camera takes a photo every 10 minutes to show the latest weather conditions. It just happened to fire at the exact nanosecond when Mother Nature connected sky and earth. When we sought out an ADOT expert on these cameras, he told us it's highly improbable that something like this could happen again.

• RIGHT ELEMENTS: A vehicle happened to be in the frame, traveling north, adding perspective and showing just how powerful this electrical discharge was. The road surface shining with rain magnifies the bolt's brilliance.

Working at ADOT's Traffic Operations Center, one way I gather traffic information is routinely scanning the scores of 511 cameras. In this case, one of the 237,000 followers of our @ArizonaDOT Twitter account, the National Weather Service, spotted the incredible shot first and tweeted it. And the rest is history.

Again, what are the odds? What are the odds that so many elements would come together to create this incredible shot?

The social media response shows that our followers understand the cosmic significance too. One of our Twitter followers said after we posted the picture, "I predict this will go viral.”

She was right. The reaction on ADOT’s Twitter and Facebook accounts shows that we, well, caught lightning in a bottle!

Stormy weather

By Dallas Hammit / ADOT State Engineer

Summer is officially here, and in Arizona, the season brings with it many weather-related safety warnings to be aware of. As we all know, it’s not just about the heat — we also have monsoons and dust storms to contend with in the coming months.

Over the years, ADOT has strived to reach out to drivers with information on how to plan ahead and take precautions to stay safe.

There are many resources for motorists to learn from, all available on ADOT’s website. You’ll find extensive safety tips on everything from what to do if you find yourself in a dust storm to prepping your car for a road trip.

For convenience, I wanted to share some of those links with you in this message.

High temperatures: Even if your vehicle has air conditioning, you should always be ready for a potential breakdown or crash that could force you to spend an extended amount of time stopped on the road. Find tips on how to prepare at azdot.gov/extremeheat. For those of you who work outside, ADOT has some helpful pages related to heat stress and heat-related illness.

Monsoons: Drivers should always be prepared and, if necessary, be ready to wait out heavy rain, high winds and blowing dust. If you do find yourself on the road during a monsoon storm, you hopefully will remember the precautions available at azdot.gov/monsoon.

Dust storms: The No. 1 thing to remember about dust storms is to NOT drive into one — avoid these walls of dense, blowing dust by safely pulling off the road. If you encounter a dust storm or a dust channel, immediately check traffic around your vehicle (front, back and to the side) and begin slowing down. Do not wait until poor visibility makes it difficult to safely pull off the roadway — do it as soon as possible. Once you’re safely off the road, turn off all vehicle lights, including your emergency flashers — you don’t want other vehicles approaching from behind to use your lights as a guide, possibly crashing into your parked vehicle. Set your emergency brake, take your foot off the brake and stay in your vehicle with your seat belt buckled until the storm passes. Find additional safety tips and videos on PullAsideStayAlive.org.

Being well informed and having a plan ahead of time can make a big difference if you’re ever driving in extreme weather. I hope you’ll visit the online safety resources listed above and share the information with your family and friends.

Crash

By John Halikowski / ADOT Director

I am sure you have heard the expression “deer in the headlights” when describing someone who stares and has a frightened look on their face. At the Arizona Department of Transportation, we are alerting drivers to be on the lookout for “deer in the headlights,” literally, on our rural roadways.

Since 2012, more collisions with animals – wildlife, livestock, and family pets – happen this time of year than nearly every other, except for October which sees the most. More than 86 percent of crashes involving animals occur in rural areas.

According to the Arizona Game and Fish Department, the higher-than-average number of wildlife-related crashes this time of year is likely related to the beginning of monsoon season. That means plants become greener and water becomes more available due to the rain. Wildlife will travel greater distances for food and water and that can mean crossing roadways. Coincidentally, we see more motorists traveling to Arizona’s high country and with that the potential for collisions with wildlife.

At ADOT we have implemented some creative solutions that promote safe travel in heavily-traveled migratory corridors. For example, we have wildlife underpasses and elk crossings along State Route 260 east of Payson, desert bighorn sheep overpasses near Hoover Dam on US 93 and two wildlife crossing structures on State Route 77 near Tucson. We have seen a 98 percent reduction in the number of elk-vehicle collisions on SR 260 over a six-year period due to fencing that link the three elk crossings.

As you travel on our rural highways, please pay attention to the signs that indicate wildlife in the area, obey the speed limit, wear your seat belts, and pay attention to the shoulders on the roadways. You will reduce the chance of colliding with an animal.

Enjoy your summer travels and avoid having your own “deer in the headlights” moment.

Clearing Pump Station Trash Buildup

By David Woodfill / ADOT Communications

It's reminiscent of the "Star Wars" trash compacter on the Death Star.

Arizona Department of Transportation workers lower themselves onto layers upon layers of trash washed into a freeway pump station. They have to clean this out to keep the system in top operating condition, something that's especially important with monsoon season approaching.

Sometimes crews can suck out the trash using large hoses. But they often have to roll up their sleeves and scoop foam cups, plastic this and that and heaven knows what else into trash bags.

The work comes with risks for workers. There's no monster like on the Death Star (did you know it's called a dianoga?), but there are occasionally snakes, rodents and other creepy crawlies like giant bullfrogs.

You want our pump stations in peak operating condition during storms. Each pump (stations usually have several) is powerful enough to drain your swimming pool in just three minutes.

Multiply that by 59, which is the number of pump stations in the Valley. Along with the many drainage grates along freeways, these pump stations clear a tremendous amount of water. That's why freeway can be drivable even when a storm has left local streets flooded.

But cups and cans and everything else that winds up on a freeway can hinder pump stations and other drainage systems by fouling grates and intakes when it rains.

So think twice the next time you may think about chucking that disposable coffee cup or hamburger wrapper out the window. It's inconsiderate and illegal to begin with. And you're potentially making it more difficult for us to keep freeways clear of water during storms.

You also can take action if you see someone tossing litter on a highway. Report it to the ADOT Litter Hotline at 877.3LITTER or kazb.org and the vehicle's owner will get a letter stating that someone was reported tossing trash from the vehicle. He or she also will get a free litter bag.

You'll get the peace of mind of knowing you've done your part to keep ADOT crews safe from dianogas.

Monsoon Mess

PHOENIX – As it prepares for monsoon storms, the Arizona Department of Transportation is asking motorists and their passengers not to toss litter along highways. Why? Because the trash can block drainage grates or wind up in the nearly 60 pump stations that ADOT operates along Phoenix-area freeways.

 

Pump stations are designed to remove large volumes of water from freeways during storms, with individual pumps able to lift more than 12,000 gallons per minute. They are part of a vast and largely unseen drainage system that can keep freeways open during storms that overwhelm local streets nearby.

Pump stations typically have three to five pumps, driven by powerful engines, to lift storm water from inside the facilities and send it into nearby drainage channels or retention basins.

Motorists can help keep ADOT’s drainage systems operating at full capacity by helping to reduce litter and other debris that can obstruct drainage grates and catch basins that collect runoff, leading to standing water along a freeway.

Another way you can help: Report those you see littering on highways to the ADOT Litter Hotline. All that’s required is providing the vehicle’s license plate number and incident details. The owner will get a letter noting that someone was reported tossing trash from the vehicle, along with a free litter bag.

ADOT works to clear litter and other debris from pump stations and freeway drainage systems all year long. Piles of litter often have to be collected by hand and hauled out of pump station storage wells. Crews or contractors also use specialized vehicles to vacuum drainage pipes that lead to pump stations.

ADOT technicians also work year round to maintain pump stations and their engines, since storms and runoff are not limited to the summer months.

As monsoon season approaches, ADOT keeps an eye on weather forecasts to prepare for challenges associated with runoff. Localized storms that drop more than 2 inches of rain in an hour can tax any drainage system.

When litter and trash are clogging the system, and water starts to build in travel lanes, ADOT maintenance crews are called away from other duties to deal with blockages. That’s another reason to think before you toss that cup or can out a car window.

PHOENIX – With strong monsoon storms forecast in much of Arizona going into the weekend, be ready to pull aside and wait out extreme weather.

Please heed this advice: Get off the highways when facing a dust storm. In almost no time, blowing dust can drop visibility to zero, especially where small dust channels afford drivers little or no opportunity to avoid this hazard.

Other tips from the Arizona Department of Transportation:

  • If you encounter a dust storm, immediately check traffic around your vehicle (front, back and to the side) and begin slowing down.
  • Don’t wait until poor visibility makes it difficult to pull off the roadway safely; do it as soon as possible. Completely exit the highway if you can.
  • Don’t stop in a travel lane or in the emergency lane. Look for a safe place to pull completely off the paved portion of the roadway.
  • Turn off all vehicle lights, including your emergency flashers. You don’t want other vehicles approaching from behind to use your lights as a guide and crash into your vehicle.
  • Set your emergency brake and take your foot off the brake.
  • Stay in the vehicle with your seat belt buckled and wait for the storm to pass.
  • Drivers of high-profile vehicles should be aware of changing weather conditions and reduce speed.

Monsoon season can produce thunderstorms with sudden, heavy rainfall. Keep these tips in mind:

  • Don’t risk crossing a flooded wash, even if it doesn’t look deep. Even a few inches of running water poses a serious risk.
  • Don’t drive around “Road Closed” signs. You risk your life and face being cited under state law.
  • If traffic lights are out, treat an intersection as a four-way stop.
  • Storm runoff can loosen boulders and rocks on slopes above highways. Stay alert in areas prone to falling rocks.
  • Inspect your windshield wipers and replace them if necessary.
  • Reduce your speed and maintain a safe distance between your vehicle and the one in front of you.
  • Avoid sudden braking, which can cause you to slide on wet pavement. To slow down, take your foot off the gas pedal and brake slowly.

More information on dust storm safety can be found at PullAsideStayAlive.org, and safety tips for driving in rainstorms are available at azdot.gov/monsoons.

Flooding

By Caroline Carpenter / ADOT Communications

You’ve heard us say it many times: “Pull Aside, Stay Alive” when visibility gets low because of dust. But do you know what to do if you encounter heavy rain or flooding on the roads?

Monsoon season is still upon us, meaning heavy downpours are possible at any time. Even though much of the state is desert, heavy rain and flash flooding occur every year.

Today we’re sharing tips about driving in a downpour:

  • Don’t risk crossing a flooded wash, even if it doesn’t look deep. It's easy to underestimate the power of running water; just a foot can carry off a vehicle.
  • Avoid areas where water is pooling in travel lanes; if possible, use center lanes and drive in the tracks of the vehicle ahead of you.
  • Do not drive around ‘Road Closed’ signs. You risk your life and face being cited under the state’s stupid motorist law.
  • If traffic lights are out, treat an intersection just like a four-way stop.
  • Expect the unexpected. Have extra supplies, including an emergency kit and drinking water, in case you experience an extended highway closure.
  • Storm runoff can loosen boulders and rocks on slopes above highways. Stay alert in rockfall prone areas.
  • Leave plenty of room between you and the vehicle ahead of you and be aware of the vehicles around you in other travel lanes. Braking and shorter stopping distances will be affected by wet roads and slippery roadway surfaces.
  • It's important to always be looking ahead for potential problems. In low-lying areas along our state highway system, debris, mud and rocks can wind up on the roadway. Keep an eye out for storm debris ahead.
  • Before you drive, inspect your windshield wipers and replace them if necessary.
  • Turn on your headlights while driving.
  • Avoid sudden braking, which can cause you to slide on the wet pavement. To slow down, take your foot off the gas pedal and brake slowly.
  • The tires of larger vehicles, like trucks and buses, create spray that can lessen visibility, so don’t follow them too closely.
  • Be cautious of hydroplaning. This occurs when a thin layer of water accumulates between your tires and the asphalt and your vehicle loses contact with the roadway. You might suddenly feel your vehicle sliding or drifting because you’ve lost traction. If you feel you are hydroplaning, ease your foot off the gas pedal until you regain traction. Do not brake suddenly. If you are sliding or drifting, gently turn your steering wheel in the direction of your slide.

Arizonans face all types of severe weather and need to be ready to take swift action when the weather abruptly changes.
