The National Weather Service has issued a flood watch for Oahu, Maui, Molokai and Hawaii island from 6 p.m. Thursday to 6 p.m. Sunday, warning of widespread rain and potential flash flooding.
A Kona low developing west of the Hawaiian Islands is expected to draw abundant moisture northward as it strengthens and eventually moves to the north early next week, according to forecasters.
“Despite this abundance of moisture in the region, today is still likely to be the driest portion of the forecast for the rest of this week, ahead of the next low pressure system that is forecast to form nearby. Winds will remain relatively light and variable through tonight,” according to NWS.
Several rounds of moderate to heavy rainfall are forecast with the heaviest rain expected Friday night through Saturday. Flooding is possible as rain showers will increase Thursday and lasting into the weekend.
“While this next system is not anticipated to be as intense as the recent kona storm event, it is important to note that it will impact an already highly saturated environment,” according to the forecast.
