Flagstaff, Ariz. – Heavy rain is expected to hit northwest Arizona on Friday, raising concerns for flash flooding across areas from the Grand Canyon to Page, including regions affected by recent wildfires. The National Weather Service (NWS) in Flagstaff has issued a Flash Flood Watch from 10 a.m. to 8 p.m., with thunderstorms potentially producing dangerous runoff and debris flows that could quickly lead to hazardous conditions.
Risk of Flash Flooding in Burn Scar Areas
The NWS has specifically highlighted the heightened risk of flash flooding near the Dragon Bravo and White Sage burn scars, where the ground’s ability to absorb water is significantly reduced due to fire damage. As a result, even moderate rainfall can quickly lead to dangerous flash floods in areas like creeks, washes, streams, and slot canyons, where water levels can rise rapidly.
Areas Affected and Safety Precautions
Communities in and around Jacob Lake, Tuba City, Supai, and Grand Canyon Village, as well as visitors in the region, are urged to avoid low-lying areas, particularly during thunderstorms. Those in hiking and recreational areas should remain aware of weather conditions, as storms can develop suddenly. If caught outdoors, hikers and visitors should move to higher ground immediately if storms approach.
The NWS warns that the flash flooding threat could last until storms clear out by Friday night, with additional watches or warnings possible if moisture lingers into the weekend.
What You Can Do: Be Prepared and Stay Informed
- Avoid low-lying areas: Steer clear of creeks, washes, streams, and slot canyons that are prone to flash flooding.
- Have multiple ways to receive alerts: Ensure you have access to weather updates, such as mobile alerts or weather radios.
- Be ready to move: If you’re out hiking or in a recreation area, have a plan to head to higher ground if you see or hear storms approaching.
With flash floods being a particular risk in burn scar areas, it is important to stay vigilant and prepared as storms move through. Keep updated on weather warnings and take necessary precautions to stay safe.
