Flash Flood Warning: Arizona Burn Scar Under Threat
1 Oct
Summary
- Flash flood warning issued for Maricopa County's Sandstone Burn Scar.
- Heavy rain caused life-threatening flash flooding in the burn area.
- Residents urged to avoid flooded streets and never drive through water.
A flash flood warning was issued for Maricopa County on Tuesday, September 29th, due to heavy rainfall over the Sandstone Burn Scar. Doppler radar indicated that thunderstorms had produced between 0.75 and 1.5 inches of rain in the area, with the potential for an additional 0.75 inches.
This intense rainfall has resulted in life-threatening flash flooding, impacting locations such as Ballantine Trailhead, Round Valley, and Sugarloaf Mountain, as well as a section of AZ Route 87. Arizona's desert terrain is particularly susceptible to flash floods, which can occur rapidly due to soil absorption issues and topography, exacerbated by wildfire damage.
Authorities emphasize the extreme danger posed by floodwaters, noting that just 6 inches of moving water can sweep a person away. Driving through flooded streets is highly discouraged, as even small vehicles can be carried away by as little as 12 inches of water. Safety advice includes immediate evacuation if ordered, avoiding all floodwater, and staying informed of weather alerts and road closures.
