A surface front approaches the islands from the northwest will result in the weakening of trade winds across the area through early Tuesday. A slight increase in low clouds in the island vicinity is expected, though mainly VFR conditions will prevail for all sites.

As the front advances near Kauai later on Tuesday, winds will turn more northerly and increase for the smaller islands. A further increase in cloud coverage with some showers are expected for the smaller islands, especially along the windward areas.

No AIRMETs are in effect or expected through early Tuesday. AIRMET Tango for TURB may be needed later on Tuesday as brisk northerly winds spread across the area. Even AIRMET MTN OBSC is a possibility along the windward mountains.
