Description

…FLASH FLOOD WATCH REMAINS IN EFFECT FROM NOON PDT /NOON MST/ TODAY THROUGH LATE SATURDAY NIGHT…

The Flash Flood Watch continues for

Portions of northwest Arizona, southeast California, and Nevada, including the following areas, in northwest Arizona, Lake Havasu and Fort Mohave, Lake Mead National Recreation Area, Northwest Deserts, and Northwest Plateau. In southeast California, Cadiz Basin, Death Valley National Park, Eastern Mojave Desert, Eastern Sierra Slopes, Owens Valley, San Bernardino County-Upper Colorado River Valley, 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.

From noon PDT /noon MST/ today through late Saturday night

Afternoon and evening thunderstorms are expected to develop both today and Saturday that will be capable of producing very high rainfall rates and areas of flash flooding. High terrain areas are favored for the highest rainfall totals, but these storms are expected to move into lower desert areas spreading the flash flood risk across much of the region as well.

Very heavy rainfall rates are expected which will lead to flash flooding. Especially in high terrain areas and in highly vulnerable debris flow areas such as burn scars. With several instances of flash flooding over the recent weeks, already flash flood prone washes and low water crossings will be likely to flood again.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

Be prepared to take action when Flash Flood Warnings are issued and check to ensure you are able to receive them.

Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles.

More Information

.Another round of high monsoonal moisture is expected through the weekend that will lead to an increased risk for flash flooding across much of the region. Isolated to scattered thunderstorms capable of very high rainfall rates will be possible each afternoon today and Saturday and could linger into the overnight hours as well.
