Flash Flood Warning
National Weather Service Phoenix AZ
1129 PM MST Thu Jul 22 2021
The National Weather Service in Phoenix has issued a
* Flash Flood Warning for...
The Telegraph Fire burn scar in...
Gila County in east central Arizona...
* Until 330 AM MST.
* At 1129 PM MST, Doppler radar indicated thunderstorms producing
heavy rain over the Telegraph Fire Burn Scar. Up to 1 inch of rain
has fallen. Additional rainfall amounts up to 1 inch are possible
in the warned area. Flash flooding is ongoing or expected to begin
shortly.
Excessive rainfall over the burn scar will result in debris flow
moving through the Bloody Tanks Wash and into Pinal Creek. The
debris flow can consist of rock, mud, vegetation and other loose
materials.
HAZARD...Life threatening flash flooding. Thunderstorms
producing flash flooding in and around the Telegraph
Fire Burn Scar.
SOURCE...Radar.
IMPACT...Life threatening flash flooding of areas in and around
the Telegraph Fire Burn Scar.
* Some locations that will experience flash flooding include...
Miami, Claypool and Central Heights-Midland City.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Move away from recently burned areas. Life-threatening flooding of
creeks, roads and normally dry arroyos is likely. The heavy rains
will likely trigger rockslides, mudslides and debris flows in steep
terrain, especially in and around these areas.
Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.
In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to cross flooded
roads. Find an alternate route.
