The National Weather Service says we are looking at several concerns with the weather for Thursday through Saturday.
First, there will be a lot of rain. The mountains could receive 6 to 8 inches of rain with locally higher amounts of 10 to 12+ inches possible, which could lead to river flooding Thursday evening through Sunday morning. The lowlands are expected to get 1 to 2 inches during this time.
There will also be strong southerly winds of 20-35 mph with gusts of 45-50 mph Thursday through Friday, which can down trees and branches, and cause local power outages.
Then, there will be large waves of 15 to 18 feet Friday, building to 19 to 22 feet Friday night for the central coast. This will lead to high surf conditions at the beaches, with beach erosion possible in some areas.
The National Weather Service urges everyone to be prepared for severe weather conditions.
