A developing low-pressure system over California is going to bring a shift in the weather pattern.
Daytime highs for the coastal valleys and beaches will be around the mid to upper 60s mostly, while the interior valleys will be closer to the upper 50s to low 60s.
A storm that is sitting right over Northern California will make its way down to the Central Coast later Monday. Northern San Luis Obispo County can expect scattered rain activity as early as 4:00 p.m. The rain activity will continue throughout the evening and continue through Santa Barbara County in the overnight hours. By Christmas morning, most of the rain will move out of the area making for partly cloudy days the rest of the day. Rain totals are expected to stay under 0.25’’ for most areas.
Aside from the rain, high winds will be a factor through Christmas Day. A high wind watch will go into effect Christmas morning for the Santa Barbara County south coast and mountains. Northwest to north winds will range from 25-40 miles per hour with potential for gusts to reach 60 mph.
A high surf advisory for San Luis Obispo County to just south of Lompoc will remain in place through Wednesday. Eight to 12 feet surf is in the forecast for Monday, which is expected to increase to 10-15 ft. with sets up to 18 feet by early Tuesday morning.
