LOCATIONS
WHAT...Flash flooding caused by excessive rainfall is possible.
INFO1
WHERE...Niihau, Kauai, Oahu, Molokai, Lanai, Kahoolawe, and Maui.
INFO2
WHEN...Through this afternoon.
INFO3
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.
INFO4
ADDITIONAL DETAILS... - An unseasonably cold upper level low moving into the Hawaiian Islands from the north will produce periods of heavy showers across the island chain today. The center of the low will settle in over Kauai around noon HST, the low will then weaken and drift slowly eastward tonight. Unstable conditions within this upper low will likely produce periods of thunderstorms and heavy showers, potentially leading to flash flooding conditions in some areas. This Flood Watch may need to be extended into the overnight hours for some counties.
