It was a rainy Friday for Kauai, Oahu, and Maui County.
Oahu and Kauai were under flood advisories for much of the day, with a flash flood warning briefly issued for Oahu as heavy rain drenched the urban areas of south Oahu from Ewa to downtown Honolulu.
Unfortunately, forecasters say it’s just the beginning of some potentially dangerous weather for the islands into early next week that could bring flooding and thunderstorms.
A storm front barreled through Kauai Friday and headed over Oahu Friday night.
The weather appears to clear for Kauai and Oahu Saturday morning, but the rain then moves over Maui County and even Hawaii Island before retreating back over Oahu and Kauai possibly Sunday.
Maui could see severely heavy rain and thunderstorms for three whole days as the system stalls overhead.
A flash flood watch is now effect for Oahu, Maui County, and Hawaii Island and lasts through Sunday afternoon.
A front will stall over the area at the same time a potent low aloft moves overhead, bringing slow-moving heavy showers and thunderstorms that could result in flash-flooding. While forecast models currently indicate the greatest threat for flooding will occur over Maui county, Oahu and the Big Island also have the potential to receive flooding rain.
Heavy rain is expected to be widespread in Maui county, impacting urban and leeward areas, which are more susceptible to flooding problems, especially in south and west Maui. These areas include Kihei, Lahaina, Kaanapali, and low-water crossings along Piilani Highway between Kaupo and Ulupalakua.
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
