Hawaii Island Weather Update for March 16th, 2020

Notice Level: Precautionary (Information Update Needed)


A Flash Flood Watch remains in effect for Hawaii Island until Tuesday afternoon. Heavy Rain with possible thunderstorms is possible as a Kona Low moves over through the state. (See Post for Further Details)

FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH TUESDAY AFTERNOON The Flash Flood Watch continues for * Kahoolawe, Kauai, Lanai, Maui, Molokai, Niihau, Oahu and the Big Island. * Through Tuesday afternoon. * A kona low west of the state will produce bands of heavy rain and thunderstorms across portions of the island chain through at least Tuesday, and possibly into Wednesday. While all islands could experience flooding rainfall, the greatest risk for flooding will be on Kauai and Oahu, where soils are already saturated due to recent heavy rain. * Heavy rain will likely affect urban and leeward locations as well as lower elevations, which are more vulnerable to flooding impacts. PRECAUTIONARY/PREPAREDNESS ACTIONS... A Flash Flood Watch means that conditions are favorable for flash flooding. Flash flooding is LIFE-THREATENING. Do not cross fast flowing water in your vehicle or on foot. Monitor later forecasts and be prepared to take action if a Flash Flood Warning is issued. If you experience heavy rain or rising water, head to higher ground immediately.
