More than 2 inches of rain has fallen in SLO. Here are the totals for your area
Another winter storm has brought heavy rainfall to San Luis Obispo County, along with strong winds, possible snow and hazards such as power outages and downed trees.
As of 9:30 a.m. Friday, already 2.18 inches of rain had fallen in 24 hours at the San Luis Obispo reservoir at the base of the Cuesta Grade, according to the San Luis Obispo County Public Works Department.
Santa Margarita Lake had measured 2.85 inches of rain by 9:45 a.m. Friday, the Public Works Department’s data show. Other areas of the county, including southern San Luis Obispo and Santa Margarita had seen just under 2 inches fall in the past 24 hours.
The heaviest rainfall came Thursday evening into Friday morning, according to the National Weather Service. Some San Luis Obispo County residents may have been awoken throughout the night to loud thunderclaps as the storm moved over the region.
The Weather Service issued a flood advisory for San Luis Obispo County on Thursday evening that expired at 10 a.m. Friday.
“The rain will likely trigger shallow mud and debris flows, minor rock falls and flooding capable of localized damage, especially in steep terrain,” the advisory said.
The higher elevations — above 2,000 feet in elevation — were expected to see up to 3 feet of snow fall through 4 p.m. Saturday, according to a winter storm warning issued by the Weather Service.
Gusting winds have downed trees in some areas and the weather caused hundreds in the Grover Beach and Oceano areas to be without power Friday morning. A wind advisory issued by the Weather Service is in effect until 4 p.m. Friday, warning of southwest winds of 20 to 35 miles per hour with gusts up to 50 miles per hour.
The rain is expected to continue throughout Friday and into the weekend, according to the Weather Service. At least another inch of precipitation appears to be in the forecast for the region through Saturday evening.
The rain comes with cold temperatures as well.
With wind chill, temperatures in San Luis Obispo are expected to drop down to about 27 degrees early Saturday morning, and not rise above 40 degrees on Saturday, according to the Weather Service.
Temperatures could drop even lower going into Sunday, with the Weather Service predicting highs of 27 degrees at around 2 a.m to 5 a.m. Sunday morning.
But with the colder temperatures could come clearer skies, as Sunday is expected to be a somewhat sunny break in the rain before storms return on Monday.
