Significant rainfall expected this weekend
Forecast from Weather Underground.
A significant amount of rainfall is expected this weekend for San Luis Obispo County, according to a special statement from the National Weather Service.
The forecast calls for rain to start falling Friday night and continue through Sunday, Weather Underground reports. The storm is expected to bring over an inch of rain to Paso Robles, the report says.
National Weather Service advisory:
A broad upper level low pressure system will interact with ample subtropical moisture in the eastern Pacific to bring large amounts of rain to northern and central California during the next few days. Our region will be on the southern edge of this significant rain-making event with the majority of the precipitation over San Luis Obispo and Santa Barbara counties Friday night through Sunday.
The first storm system will bring steady rain to much of San Luis Obispo and Santa Barbara counties on Friday night…with the rain band gradually sagging southward on Saturday…when rain will be likely across much of the forecast area. There will be a chance of showers north of Point Conception on Saturday night…followed by another band of steadier rain on Sunday across San Luis Obispo and Santa Barbara counties.
San Luis Obispo will feel the brunt of this storm system…with rainfall amounts generally ranging between 1 and 3 inches from Friday night through Sunday…except locally higher amounts across the coastal hills in the northwest portion of the County. For Santa Barbara County…rainfall amounts will generally range between .5 and 1.5 inches. Rainfall totals are expected to drop off sharply across Ventura and Los Angeles counties…with most areas seeing less than .25 inches…except local amounts up to .50 inches across western Ventura County.
The higher rainfall amounts in San Luis Obispo and Santa Barbara counties could create ponding of water on the roadways with minor urban flooding in poor drainage areas. Accumulating oil and residue on highways could result in even more hazardous driving conditions on the wet roadways this weekend. Due to the warm nature of this storm system…snow levels are expected to remain well above resort levels. There will likely be gusty southwest winds up to 50 mph in the mountains of San Luis Obispo and Santa Barbara counties on Friday night.
Residents of southwest California are urged to stay tuned to the latest National Weather Service forecasts through the weekend.
