Tonight
Partly to mostly cloudy skies are expected tonight with increasing showers for windward areas overnight. Leeward areas have a chance of a few evening showers, then clearing is expected through the night as the land breeze takes hold. Trade winds are forecasted from 10 to 20 mph. Low temperatures from 71° to 76° are expected.
Looking Ahead
Moderate trade winds are expected to slowly weaken through the week. Clouds and showers will continue to favor windward slopes all day, but afternoon buildups will increase each day, perhaps producing brief showers by late in the week.
