The National Weather Service has issued a flood watch for all the main Hawaiian Islands through Sunday afternoon. A low aloft will move over the islands through today resulting in an unstable atmosphere, the flood watch alert said. A flash flood warning has been in effect for Oahu until 9.30 am.
A report said periods of heavy showers over already saturated ground may quickly lead to runoff and flash flooding. Water levels in streams are expected to continue to rise. Flash flooding is ongoing or expected to begin shortly.
Some locations that will experience flash flooding include Honolulu , Ahuimanu, Kaneohe, Kahaluu, Waiahole, Kalihi, Maunawili, Moanalua, Aiea, Halawa, Waikane, Kaneohe Marine Base, Manoa, Kailua, Salt Lake, Pearl City, Palolo, Waimanalo, Kaaawa and Mililani.
The combination of heavy rain and high surf has also resulted in the closure of Bayfront Highway in Hilo as large waves have washed debris over the roadway.
