You don’t have to live near an ocean, lake, or river to be
subjected to flash flooding. Even desert areas like southern Arizona have their
share of flash floods, brought on by heavy rains that have nowhere to go except
raging down what used to be dry arroyos or washes only a few moments before.
And every town and city across the country is vulnerable to storm drains and
sewer systems overflowing and/or backing up because of too much rain for them
to handle or debris clogging them.
Flash floods may be one of the most dangerous
weather-related phenomena because they can happen anywhere. The water rises so
fast and flows so swiftly that roads can be particularly dangerous. Vehicles on
them can be swept away almost before drivers realize what’s happening. However,
protecting yourself from a flash flood is simple, as long as you stay alert and
drive carefully. All you have to do to arrive safely at your destination is to
remember to take a few basic safety precautions. Here are the top three rules
for safe driving during a flash flood warning.
Rule 1. Never Drive Through Flood Water
Just because flood water looks shallow doesn’t mean it is.
It’s impossible to judge its depth, especially at night. Additionally, the
pavement or ground under it may already have been compromised and there could
be a deep hole where a flat surface used to be.
According to the Federal Emergency Management Agency (FEMA):
- Six
inches of water will reach the bottom of most passenger cars, causing loss
of control and potential stalling.
- One
foot of water will float many vehicles.
- Two
feet of rushing water will carry away most vehicles, including SUVs and
pickups.
Your kids have undoubtedly heard it from one of the local
weathermen at a school visit: “Turn around, don’t drown!” This is the slogan
that the National Weather Service has campaigned on for years to prevent flash
flooding deaths. Find another route rather than proceeding through floodwaters.
Rule 2. Get Out ASAP if Your Car Submerges
While it’s dangerous to get into flood waters, it’s even
more dangerous to remain in a car that’s submerging. Stay calm. Release your
seatbelt. Open your window and escape through it. If your window won’t open,
try to break it with anything handy. Remain on the car roof as long as
possible. If your car gets hung up on a tree or other heavy object, try to get
onto that instead of your car roof.
If you can’t break the window, wait for your car to fill
with water while keeping your hands securely on the door handle. Do not panic.
When the car is almost full, take a deep breath, open the door, and swim to the
surface. If you’re swept away by the flood waters, try to keep your feet
pointed downstream and direct your body over rather than under obstacles. Do
your best to avoid any downed power lines. If possible, grab onto a tree or any
other heavy object you come to and stay there until rescued.
Rule 3. Never Park or Camp on River Banks or Near Washes
While it may be scenic to camp on a river bank or near a dry
wash in the Desert Southwest, don’t do it. Heavy thunder storms can pop up at
any time. Carry a battery-operated weather radio or install a weather app on
your phone so you can check local weather before going to sleep at night.
By learning these three rules, you’ll be as safe as possible
if and when you’re faced with a flash flood emergency.

rule for surviving flood waters is not to get into them in the first place.
