* WHAT...Flash flooding caused by excessive rainfall is possible.
* WHERE...Niihau, Kauai, Oahu, Molokai, Lanai, Kahoolawe, and Maui.
* 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 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.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.
