The National Weather Service has extended a Flash Flood Watch for all of the Hawaiian Islands through Thursday afternoon.

According to the NWS, “A Kona Low west of the state will continue to produce bands of heavy rain and thunderstorms across portions of the island chain through Thursday. While all islands could experience flooding rainfall, the greatest risk for flooding will be on Kauaʻi and Oʻahu where soils remain saturated due to recent heavy rain. Another large heavy shower band forming just west of Kauaʻi will move into the western half of the state later this morning.”

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

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.
