HAWAII ISLAND – The Big Island of Hawaii is again under a Flash Flood Warning as well as a Flood Advisory, both issued by the National Weather Service (NWS) this evening.
The Flash Flood Warning is for the eastern half of the Ka’u district. NWS says Hawaii County Civil Defense reported that Highway 11 was closed between mile markers 58 and 59 at Kawa Flats due to water over the highway. Forecasters say radar is “showing areas of light to moderate rain in the area, but there was heavy rain earlier this afternoon upslope which is now causing excessive runoff over the highway.” The warning is in effect until 9 p.m.
Meanwhile, a Flood Advisory remains in effect for West Hawaii until 7:30 p.m. HST.
At 5:20 p.m. radar indicated that most of the heavy showers over the leeward side of the Big Island have dissipated with just a few spotty showers continuing. However, runoff remains high from earlier heavy rains and the Flood Advisory remains in effect.
