Flood Watch issued October 27 at 2:29AM HST until October 27 at 6:00PM HST by NWS Honolulu HI
...FLOOD WATCH FOR ALL HAWAIIAN ISLANDS THROUGH THIS AFTERNOON... * WHAT...Flash flooding caused by excessive rainfall continues to be possible. * WHERE...All the main Hawaiian islands. * WHEN...Through this afternoon. * IMPACTS...Flood prone roads and other low lying areas may be closed due to elevated runoff and overflowing streams. Urban areas may receive more significant flooding and property damage due to rapid runoff. * ADDITIONAL DETAILS... - An upper low will move over the islands today and result in continued unstable conditions within a very moist atmosphere. There will be enough instability to produce periodic showers. Rain could become locally heavy, with a chance for isolated thunderstorms, particularly over windward areas. Periods of heavy showers over already saturated grounds could quickly lead to runoff and flash flooding issues. Water levels in elevated streams could rise rapidly with additional heavy rain.
