Alerts issued for flash flooding, high winds from approaching storm system
HONOLULU (HawaiiNewsNow) – Several severe weather alerts will be taking effect as a strong winter storms system approaches Hawaii.
The HNN First Alert Weather Team earlier declared a First Alert Weather Day statewide from Wednesday night through Friday morning.
The National Weather Service says a Flood Watch will be in effect for all main Hawaiian islands from Wednesday evening through Friday morning.
A High Wind Watch will also take effect statewide Wednesday evening through late Thursday night for strong southwest winds of 20 to 35 miles per hour with gusts near 55 miles per hour.
The strongest winds are expected over windward and mauka areas of Kauai and Oahu. However, parts of Maui County and Hawaii Island may also see strong and potentially damaging winds.
A Winter Storm Watch will be in effect from late Wednesday night through Friday morning for the summits of Haleakala, Mauna Kea and Mauna Loa.
Periods of snow and mixed precipitation will be possible, with the potential of snow accumulations of up to ten inches for Mauna Kea and Mauna Loa, and up to four inches for the summit area of Haleakala.
A light glaze of ice will also be possible on roads and other surfaces as temperatures drop below freezing.
The storm system may also impact mariners in waters around Kauai, where a Gale Watch will be posted from Wednesday evening through Thursday afternoon. There’s a chance for strong winds causing hazardous seas that can capsize or damage vessels and reduce visibility.
The severe weather conditions are expected from the strong winter low pressure system that is forecast to develop west of the state on Wednesday and then pass to the north of Kauai on Thursday, with an associated cold front bringing a chance of heavy showers and thunderstorms over the western end of the state starting Wednesday evening.
