...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.
