...FLASH FLOOD WATCH IN EFFECT FROM NOON HST TODAY THROUGH
The National Weather Service in Honolulu has issued a
* Flash Flood Watch for Kahoolawe, Kauai, Lanai, Maui, Molokai,
Niihau, Oahu and the Big Island.
* From noon HST today through Wednesday afternoon.
* Increasingly moist and unstable air will overspread the islands
today and Tuesday. A strong upper level disturbance will cause a
surface trough or low to develop near the islands over the next
couple of days, enhancing the potential for heavy downpours and
thunderstorms that could lead to flash flooding. Any heavy
showers will be spotty this afternoon, but could become more
widespread by Tuesday. Conditions should gradually improve later
in the day on Wednesday.
* Some streams and normally dry gulches are expected to run high
and could quickly overflow their banks. Intense rainfall in poor
drainage and urban areas could also lead to flash flooding.
A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.
Keep tuned to later forecasts and be prepared to take action
should Flash Flood Warnings be issued.
