Flash Flood Watch Extended Statewide

Posted December 3, 2021, 4:46 PM HST ·Updated December 3, 4:47 PM

The National Weather Service has extended a flash flood watch for Kauaʻi County through Tuesday afternoon. The advisory is statewide.

A prolonged period of heavy rainfall is anticipated as a slow-moving Kona low storm develops west of Kauaʻi, and moisture associated with that, front stalls over the islands. According to NWS, the stalling front will bring the greatest potential for heavy rain over Maui and the Big Island.

As the low forms west of Kauaʻi on Saturday, moisture associated with the front will gradually spread back toward Oʻahu and Kauaʻi County. This will bring the threat of heavy rainfall to all islands well into next week.

Flash flooding caused by excessive rainfall will be possible. 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. Landslides may also occur in areas with steep terrain.

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.
