A Flash Flood Watch continues for Kahoʻolawe, Kauaʻi, Lānaʻi, Maui, Molokaʻi, Niʻihau, Oʻahu and the Big Island of Hawaiʻi through Tuesday afternoon

The National Weather Service says a Kona Low forming west of Kauaʻi will produce bands of heavy rain and thunderstorms across the state through at least Tuesday, and possibly into Wednesday. While all islands could experience flooding rainfall, Kauaʻi and Oʻahu will be at the greatest risk.

“Heavy rain will likely affect urban and leeward locations as well as lower elevations, which are more vulnerable to flooding impacts,” according to the NWS.

A Flash Flood Watch means that conditions are favorable for flash flooding. Motorists and pedestrians are reminded not to cross fast-flowing water in their vehicle or on foot.

The public should 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,” the NWS says.
