Kahului, HI Weather Warnings

Issue Date: 304 PM HST Thu Dec 2 2021
...FLOOD WATCH IN EFFECT THROUGH MONDAY AFTERNOON... * WHAT...Flash flooding caused by excessive rainfall is possible. * WHERE...All Hawaiian Islands. * WHEN...Through Monday afternoon. * IMPACTS...Significant flooding may occur due to the overflow of streams and drainages. Roads in several areas may be closed, along with property damage in urban or low lying spots due to runoff. Isolated highways, such as the Belt Highway in the Big Island`s Kau District, and Piilani Highway on Maui, may be closed in one or more locations, resulting in long detours or even the isolation of communities. Landslides may also occur in areas with steep terrain. * ADDITIONAL DETAILS... - A cold front will move over the islands from the northwest tonight and Friday, initially bringing a relatively short period of heavy rainfall to Kauai and Oahu. The front is expected to stall near Maui County and the Big Island late Friday, bringing the potential for an extended period of heavy rainfall as a slow-moving kona low forms west of Kauai on Saturday. As the low develops, moisture associated with the front will spread back toward the west, bringing the threat of heavy rainfall to all islands, with this threat likely persisting well into next week. PRECAUTIONARY/PREPAREDNESS ACTIONS... Be prepared to take action if a Flash Flood Warning is issued. If you experience heavy rain or rising waters, head to higher ground immediately. A 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. &&
