For leeward areas, partly cloudy skies are expected tonight with clearing as the night goes on. Windward spots are partly cloudy with scattered showers. East winds are forecasted from 10 to 20 mph. Low temperatures from 73° to 78° are expected.
Looking Ahead
Easterly trade winds will remain in the gentle to locally moderate range today, weak enough to allow afternoon sea breezes to set up along most leeward areas. Showers will remain focused across windward areas, with spotty afternoon showers developing across leeward areas. Locally fresh trade winds and typical windward and mauka showers will return on Wednesday, with an increase in showers possible during the weekend. Uncertainty is rather high headed into the weekend. An increase in moisture associated with tropical depression 08°E is possible as early as Saturday night. The official forecast from the National Hurricane Center places the weakening tropical cyclone a couple hundred miles east-southeast of the Big Island on Saturday. Note that tropical cyclone forecasts this far out contain a high degree of uncertainty, so the forecast was broadly painted wetter Sunday and Monday.
