HONOLULU (HawaiiNewsNow) - An upper level low will linger over the eastern half of the state through tomorrow before slowly drifting westward across the entire island chain this weekend. Expect continued unsettled weather with periods of showers, locally heavy at times, with isolated thunderstorms through Sunday. A surface low developing under the upper low will weaken the trades from east to west on Friday and Saturday. Southeasterly winds will pull in deeper tropical moisture over the eastern islands next week Tuesday and Wednesday with additional rounds of unsettled weather in the long range forecast. A Flash Flood Watch remains in effect statewide through early Friday morning.
The High Surf Warning for E facing shores has been extended overnight, while the same has been done for the High Surf Advisory for exposed N facing shores. While surf may diminish below Warning/Advisory levels on the Big Island and Maui on Friday, it may remain elevated from Molokai to Kauai as the low sends new swells toward the islands. A small to moderate WNW swell this weekend will produce below advisory-level surf along N and W facing shores.
