The National Weather Service in Phoenix has issued a * Flash Flood Warning for... Gila County in east central Arizona... Maricopa County in south central Arizona... Pinal County in southeastern Arizona... * Until 445 PM MST. *
At 1251 PM MST, Doppler radar indicated thunderstorms producing heavy rain across the warned area which includes portions of the Woodbury burn scar and the Reevis School Basin.
Up to one inch of rain has already fallen. Flash flooding is expected to begin shortly.
* Some locations that will experience flooding include... Roosevelt, Roosevelt Dam and Tonto National Monument. Excessive rainfall over the burn scar will result in debris flow moving through the Woodbury Burn scar and the Reevis School Basin.
The debris flow can consist of rock, mud, vegetation and other loose materials.
PRECAUTIONARY/PREPAREDNESS ACTIONS... Excessive runoff from heavy rainfall will cause flooding of small creeks and streams, country roads, farmland, and other low lying spots. 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. 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. Flooding is occurring or is imminent. It is important to know where you are relative to streams, rivers, or creeks which can become killers in heavy rains. Campers and hikers should avoid streams or creeks.
