[NWS Bay Area 🌉 @NWSBayArea]

Large breaking waves of 20 to 30 feet are expected Thursday night through Friday at all Pacific Coast beaches. Stay off of jetties, piers, and rocks, keep pets on a leash and away from the water, and never turn your back on the ocean! #CAwx

[NWS Los Angeles @NWSLosAngeles]

Here is a graphic from NOAA's Weather Prediction Center for rainfall expected from 4 PM Wednesday Feb. 12th through 4 PM Friday Feb. 14th. Most of the rain over SW California is expected Thursday and Thursday night, with lighter showers the remainder of the time. #CAwx

[CoastsideCERT @CoastsideCert]

We are already seeing some effects of the rain. As the ground saturates and and winds pick up, pay attention to any shallow rooted or weak/damaged trees and stay clear. Be prepared for power and communication outages.

[NWS Bay Area 🌉 @NWSBayArea]

Here's a look at the forecast storm total precipitation between tonight and Friday. Our biggest concerns are flooding of creeks and streams and an increased risk for downed trees due to the combination of wind and moist soils. Turn around, don't drown! #CAwx
