The National Weather Service in Phoenix has issued a life-threatening flash flood warning for parts of Gila and Maricopa counties, effective until 7 p.m. Wednesday.
The warning was prompted by Doppler radar detecting thunderstorms producing heavy rain across the region. Meteorologists reported that between 0.5 and 1 inch of rain has already fallen, with an additional 0.5 to 1 inch possible. This significant rainfall is expected to cause ongoing or imminent flash flooding.
Specific areas at risk of life-threatening flash flooding of creeks, streams, urban areas, highways, and underpasses include Apache Lake and Tortilla Flat.
Officials are urging the public to take immediate precautions, particularly campers and hikers, who should avoid streams and creeks. The NWS strongly advises motorists to “Turn around, don’t drown,” emphasizing that most flood-related deaths occur in vehicles. Never attempt to drive through a flooded road, as the road may be damaged, and as little as two feet of moving water can sweep a vehicle away.
A flash flood warning, like the one currently in effect, is issued when flooding is imminent or occurring, signaling the need to move to higher ground immediately. It is more severe than a flash flood watch, which indicates that conditions are favorable for potential flooding.
During a flood warning, residents should:
- Evacuate immediately if advised to do so.
- Monitor local news via battery-operated radio or television for emergency updates.
- Stay out of floodwater. Swiftly moving water just six inches deep can knock a person off their feet.
- Avoid fire hazards and be aware that children should not play in or near flowing water, which can hide dangerous debris.
