Winds will generally remain southwesterly to south easterly through late next week as the ridge persists, briefly turning northerly on Tuesday and Wednesday along the south coast ahead of a weak cold front. Winds will then turn north to northeasterly along most of the coast next Friday ahead of a cold front approaching the state from the west.
