Tonight
Windward and southeastern facing slopes are expected to get numerous showers tonight. Leeward spots are forecasted to be partly cloudy. East/southeast winds are forecasted around 15 mph. Low temperatures from 69° to 74° are expected.
Moderate to strong trade winds are expected to weaken and become more southeasterly through mid-week and change little into the weekend. Most clouds and rain will occur over slopes facing into the wind, but showers will be more likely to drift leeward later in the week, especially at night. Southeast winds also may bring volcanic haze from Kilauea to the islands by the weekend.
