High Santa Ana winds are in the Southland Saturday, with gusts up to 70 mph expected overnight in the windiest areas.
Wind advisories issued by the National Weather Service were in effect until noon Sunday in the San Gabriel Valley, and until 3 p.m. Sunday in coastal Orange and Los Angeles counties and downtown L-A.
The gusts are forecast to reach 25 to 30 knots at Avalon Harbor, generating waves of 3 to 5 feet, which could cause boats to break from their moorings and capsize near shore, according to the NWS.
The moderate to strong Santa Ana winds could blow down large objects such as trees and power lines, forecasters said. Power outages are possible, and travel could be difficult, especially for high-profile vehicles. This includes Interstate 5 and Highways 14 and 126.
Gusts could reach 45 mph from Malibu to the Hollywood Hills, 60 mph in the San Fernando Valley, 65 mph in Santa Clarita and 70 mph in the mountains.
