Flash Flood Warning
National Weather Service Phoenix AZ
1143 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 345 AM MST.
* At 1143 PM MST, Doppler radar indicated thunderstorms producing
heavy rain over the Telegraph Fire Burn Scar. Between 0.5 and 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 Dripping Springs and downstream areas. 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...
Hayden, Winkelman and Christmas.
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.
Be especially cautious at night when it is harder to recognize the
dangers of flooding.
