The Flash Flood Watch continues for

* Kahoolawe, Kauai, Lanai, Maui, Molokai, Niihau, Oahu and the
  Big Island.

* Through Wednesday afternoon

* Increasingly moist and unstable air will overspread the islands
  tonight and Tuesday. Spotty intense showers, mainly windward and
  mauka tonight, could become more widespread by 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. 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


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. Consider postponing camping
or hiking trips until the weather improves.
