HONOLULU, Hawaii (HawaiiNewsNow) - Dry and breezy conditions today with mostly to partly sunny skies plus windward and mauka showers drifting leeward at times, but that will change. Starting tomorrow an upper level trough along with an influx of moisture from the east and southeast, will likely increase trade wind shower coverage and intensity tomorrow through the weekend. National Weather Service wind forecast calls for 15-30 mph winds, with gusts up to 50 mph possible.
Wind Advisories are now in effect for parts of Maui County and portions of Hawaii Island
Strong trade winds will also build large wind-driven easterly seas. Surf heights along eastern-facing shores will exceed surf advisory levels this week. Thus, a High Surf Advisory is in effect for most eastern exposures for the remainder of the week; check with lifeguards before going into the water. A couple of small, overlapping relatively longer period west to northwest swells will travel around the islands the next few days. The first of these swells leveled out yesterday afternoon. The second set of similar low west to northwest swells will be moving through today to late week. Surf along north and west-facing shores will remain well below HSA levels through Friday.
With Small Craft Advisories in effect for most coastal waters, check with your boat captains if you are on a charter.
