Flash Flood Warning
National Weather Service Phoenix AZ
1028 PM MST Mon Aug 16 2021

The National Weather Service in Phoenix has issued a

* Flash Flood Warning for...
  The Woodbury burn scar in...
  Gila County in east central Arizona...
  Maricopa County in south central Arizona...
  Pinal County in southeastern Arizona...

* Until 630 AM MST Tuesday.

* At 1028 PM MST, Doppler radar indicated thunderstorms producing 
  heavy rain over the Woodbury Burn Scar. Between 0.5 and 1.5 inches 
  of rain have fallen. Additional rainfall amounts of 0.5 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 Woodbury. 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 Woodbury
           Burn Scar.

  SOURCE...Radar.

  IMPACT...Life threatening flash flooding of areas in and around
           the Woodbury Burn Scar.

* Some locations that will experience flash flooding include...
  Roosevelt, Tonto National Monument and Roosevelt Estates.

This includes the following highways...
	AZ Route 188 between mile markers 234 and 243.

This includes the following streams and drainages...
  Barranca Creek, Lewis and Pranty Creek, Salt River, Reavis Creek, 
  Pine Creek, Campaign Creek, Tonto Creek, Tortilla Creek and Burnt 
  Corral Creek.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

This is a life threatening situation. Heavy rainfall will cause 
extensive and severe flash flooding of creeks...streams...and 
ditches in the Woodbury Burn Scar. Severe debris flows can also be 
anticipated across roads. Roads and driveways may be washed away in 
places. If you encounter flood waters...climb to safety.

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.
