A Flood Advisory has been extended until 11:45 p.m. for south and southeast portions of the Big Island.
The National Weather Service in Honolulu said at 8:41 p.m., radar indicated areas of moderate to heavy rain persisting over the Ka'u District, from west of Volcano to Wood Valley.
Additional areas of moderate rain were moving onshore, with rainfall rates of one to two inches per hour occurring across parts of the area. Minor flooding in poor drainage areas is expected. Flooding may also develop along Highway 11 at Kawa Flats and other low-lying areas if heavy rains persist.
Locations in the advisory include but are not limited to Kawa Flats, Naalehu, Hawaiian Ocean View, Volcano, Pahala, Hawaii Volcanoes National Park, Glenwood, Wood Valley, Punaluu Beach, Waiohinu and Kalapana.
Persons in those locations should avoid streams, drainage ditches and other low-lying areas that are prone to flooding. Rainfall and runoff will also cause hazardous driving conditions due to ponding, reduced visibility and poor braking.
