The on-again, off-again pattern of rain is back on again, with showers expected today, the final day of winter.
Then, as spring debuts Sunday, an even stronger storm arrives, packing not only generous amounts of rainfall, but high winds and big waves, forecasters say.
The Central Coast’s biggest winter storm came Dec. 18-19, but it packed little in the way of winds or ocean swell, said John Lindsey, a PG&E community relations official who has been forecasting Central Coast weather for more than 20 years.
With Sunday’s storm, “There will be winds gusting up to 55 mph, the season’s largest waves, and we will get a lot of rain,” he said.
From 1 to 3 inches of rain is expected in the coastal valleys and up to 4 inches in the mountains.The National Weather Service has issued a wind advisory for San Luis Obispo County.
“This storm has the potential to bring significant wind impacts to the region, including downed trees and power lines, as well as power outages,” the Weather Service reported.
A high surf advisory has been issued by the weather service for today, with waves between 10 and 13 feet and local sets of 15 feet possible, according to the Weather Service. Forecasters there said the advisory might be extended into Sunday, when Lindsey expects the winds will help generate seas of 11 to 13 feet.
Temperatures this weekend will be cool, with highs in the 50s countywide and lows in the 40s.Lindsey said big storms occurring in March are not unusual: On March 9 and 10, 1995, a storm that parked over the county dumped 8.54 inches of rain on the Diablo Canyon nuclear power plant in 24 hours.
