In California...Cadiz basin...Death Valley National Park...eastern Mojave Desert... eastern Sierra slopes...morongo basin...Owens Valley...San Bernardino County- upper Colorado River valley...western Mojave Desert and White Mountains of Inyo County. In Nevada... Esmeralda and central Nye County...Lake Mead National Recreation Area...Las Vegas Valley...Lincoln County... northeast Clark County...Sheep Range...southern Clark County...Spring Mountains-Red Rock Canyon and western Clark and southern Nye County.
* Through 9 PM this evening
* a large upper level disturbance could potentially organize strong thunderstorms with heavy rainfall through this evening. With plenty of moisture in place across the southern Great Basin and Mojave Desert...thunderstorms could easily produce one to two inches of rainfall in a short period of time. Areas near recent burn scars will also be more susceptible to increased runoff and flash flooding or debris flows.
* Most flood deaths occur in automobiles. Never drive your vehicle into areas where the water covers the roadway since flood waters are usually deeper than they appear. Just one foot of flowing water is powerful enough to sweep vehicles off the Road. When encountering flooded roads make the smart choice...turn around...dont drown.
Precautionary/preparedness actions...a Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.
You should monitor forecasts and be prepared to take action should flash flood warnings be issued for your area.
