The Surprise Public Works Department provides sand and bags free of charge to Surprise residents in the event of surprise flooding. The sand and bags will be located at the following locations ..., following a major rain event, in which flooding may occur

Tips: If You Are Driving

Slow down! The first rain of summer brings oils and other automotive fluids to the road surfaces, causing unusually slick conditions.

Do not attempt to cross flooded roadways. Even shallow running water exerts great pressure and can sweep your car off the road or stall your engine.

Keep your foot off the brake pedal. Drivers may see your lights and assume you are on the road in motion

Lightning is dangerous no matter where you are. If you find yourself driving during lightning strikes...

Stay inside the car. In the unlikely event of a lightning strike, it may burst a tire, explode the battery or start your car if the ignition switch is on.

Switch it off and take out the ignition key.

Avoid parking your car in open fields, high land, trees, poles and standing bodies of water.

Under the Arizona "Stupid Motorist Law" a driver requiring rescue from a flooded wash, with posted warning signs or gates, may also be held responsible for the cost of the water rescue; on successful rescue.

If you are not driving, stay indoors

Do not swim

Do not play golf

Do not hold or fire a gun. Lightning strikes faster than a bullet.

Avoid using cell phones. In any case our 911 operators will not be attending any calls during this period. This because, even cordless phones can cause a shock when lighting strikes nearby.
