Cloudy and breezy conditions continue across the state this morning due to strong high pressure to the north and an upper level disturbance several hundred miles west of Kauai. Water vapor imagery showed plenty of moisture being drawn northward toward the islands, particularly the west end of the state.
Although most of the showers will continue to focus on windward and mountain locations today, heavier showers and perhaps thunderstorms are possible for Kauai and Niihau due to a pulse of energy aloft just west of the state. Latest radar showed a shield of moderate to heavy showers with a few storms embedded moving in from the west toward Niihau and Kauai.
Expect this trend to continue through the morning hours today. The possibility of heavy showers will continue to move east and dampen Oahu and the rest of the state Friday through Saturday. A drier weather pattern with very light winds should take hold by Monday and hold through mid-week.
Surf continues to be dangerously large along north and east shores. This swell has been slow to decline, so continue to use extreme caution along those coasts. Experts only in the water. Check with lifeguards before you even approach the ocean. Stay well back from the crashing surf along rocky coastlines.
Waves today will be 18-25 feet north and east, 2-3 feet west, 1-3 feet south. A small SW swell will fill in Friday.
High surf warning for north and east shores.
Small craft advisory for all Hawaii waters.
Caution to Mariners in harbors with northern exposure due to harbor surge and breaking waves at entrances.
