The National Weather Service in Reno issued a flash flood warning for Northern Mono and Alpine Counties in northern California and Douglas County in Nevada.

They said the warning should expire around 7 p.m.

They said thunderstorms producing heavy rain are moving toward the burn scar of the Slinkard Fire and flash flooding is expected to begin if the rainfall intensity remains the same.

Areas that could experience flooding include Topaz Lake, Junction U.S. 395 and along CA 89.

They are warning that debris flow could move toward Highway 395 if excessive rain falls over the Slinkard burn scar. The debris can consist of rock, mud, vegetation and loose materials.

The National Weather Service in Reno says life-threatening flooding of creeks, roads and normally dry arroyos is likely and people should stay away from recent burned areas. Heavy rains can also trigger rock slides, mudslides and debris flows in steep terrain.
