Heavy Rain Pounds Coachella Valley, Flash Flood Watch Issued
PALM DESERT - A flash flood watch for the mountains and deserts in the Coachella Valley continues until 8 p.m. Tuesday.
The National Weather Service reports very moist and conditionally unstable air will remain over southwest California through most of this week. A near stationary low pressure system over Imperial and eastern Riverside County is producing additional instability.
Thunderstorms with flash flood producing rainfall are possible through Tuesday evening over the mountain and desert zones of southwest California.
Excessive runoff from heavy downpours may cause rapid filling and overflowing of normally dry washes and small creeks and low lying areas. In addition there is a threat of rock and mud slides below steep terrain in the mountains and recently burned areas.
