What’s ahead in SLO County’s forecast?
The Weather Service forecast a 30% chance of showers before 4 p.m. on Friday, and a 50% t0 60% chance of rain after 10 p.m.
The forecast predicted a 100% chance of rain on Saturday and a 60% chance of rain on Sunday.
A slight chance of rain will continue through Thursday.
A high surf advisory will be in effect for San Luis Obispo County beaches until 9 a.m. on Saturday.
The forecast calls for large, breaking waves of 10 to 15 feet and “dangerous” rip currents.
The Weather Service urged people to stay out of the water and off of rock jetties, which “can be deadly in such conditions.”
“There is an increased risk for ocean drowning,” the Weather Service said. “Rip currents can pull swimmers and surfers out to sea. Large breaking waves can cause injury, wash people off beaches and rocks, and capsize small boats near shore. Minor beach erosion and minor flooding of usually dry areas may occur.”
