Rainfall and wind beginning early Friday may cause unsafe conditions throughout areas of San Bernardino County, according to the National Weather Service.
Wind gusts from 40 to 45 mph are expected in the valleys but mostly in the desert communities of Yucca Valley and Twentynine Palms.
Rain began falling overnight Thursday but the storm is expected to pick up on Friday.
National Weather Service forecasters predict:
- A foot of rainfall in Crestline and other south facing mountain areas where rainfall rates of one to two inches per hour can occur
- A half foot to a foot in Lytle Creek
- Four to five inches in Rancho Cucamonga and other foothill communities
- One to two inches in the High Desert
- Ten inches in Yucaipa and Forest Falls
These rainfall amounts may lead to flash flooding.
The heavy rains on Friday will transition to showers through Friday night and Saturday, ending on Sunday.
Although the sun will peek out of the clouds on Saturday, rainfall is expected to continue throughout the day.
County crews and departments are mobilized to address storm-related issues.
Residents are advised to stay clear of flood control debris basins and channels. Persons can be swept away by a surge of water runoff, mudflow, or debris flow. Do not drive where water is over the road as flood waters can rise rapidly and sweep a car and its occupants away.
