Looking Ahead
Surface high pressure will remain far northeast of the area through early next week, with light to moderate trade winds prevailing over the islands. Areas of tropical moisture will move west across the state through the weekend. Showers will focus mainly over windward slopes, with afternoon clouds and showers, a few briefly heavy, developing over interior and leeward areas. Drier and breezy trade wind weather will return Monday, as a new high strengthens north of the state. Tropical Storm Lane is forecast to strengthen to a hurricane and move into the central Pacific during the weekend. It is too soon to know if Lane will directly affect the Hawaiian Islands.
