1) Mainly dry and breezy weather conditions are expected through Thursday of this week. Gusty NE flow through middle of week becomes less gusty and more northerly Thursday.
2) Brief minor coastal flooding for the high tide cycle Wednesday evening for some spots, and possibly again for at least the Thursday morning high tide cycle.
3) Strong high pressure will set the stage for much lighter winds Friday into early next week as well as a gradual warming trend.
