Snow, heavy rainfall and gusty winds swept through San Luis Obispo County on on Friday evening leading to road closures, flooding and power outages.

SLO County is under a winter storm warning until 4 p.m. Saturday, according to the National Weather Service. With more rain and snow possible throughout the day, the weather service recommends residents avoid driving if possible.

The storm left more than 3,694 SLO County PG&E customers without power on Saturday morning.

Shortly before 11 p.m. on Friday, 1,715 PG&E customers in Morro Bay lost power. PG&E determined an equipment issue caused the outage. The utility estimates the power will be restored by 5:55 p.m.

On Friday evening and early Saturday morning, seven outages in rural Santa Margarita and Creston left 1,358 customers in the dark. The utility blames the outages on the storm and their equipment. Because of issues with access, PG&E has not yet provided an estimated time power will be restored for these county residents.

Smaller outages are ongoing in Grover Beach and in the eastern and southern sections of the county.
