...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.
