South winds of 30 to 40 mph with gusts of 60-70 mph are forecast for the beaches and headlands. The forecast inland is for south winds of 25 to 35 mph with gusts 50 to 60 mph. Winds will increase fairly early Tuesday morning and continue through a good part of the afternoon. The winds may be strong enough to damage trees and cause power interruptions. Isolated power outages are possible, and travel may be difficult due to damaged trees in the roadway.
A high wind warning means a hazardous high wind event is expected or occurring. Sustained wind speeds of at least 40 mph or gusts of 58 mph or more can lead to property damage. Trees may fall across roadways with little warning.
