...flash flood watch remains in effect through friday afternoon...

the flash flood watch continues for

* the entire state of hawaii.

* through 6 pm friday.

* the remnants of an old front lingering across the state in
  combination with an upper level trough moving overhead, will
  bring the threat for heavy rainfall and flash flooding. the
  heaviest rainfall is expected to fall from oahu eastward to the
  big island, particularly in windward areas. even though 
  widespread heavy rainfall is not expected on kauai, given the 
  high levels of saturation from recent rainfall, any additional 
  moderate rain falling for an extended period of time could 
  quickly result in flooding problems.
* rapidly rising water levels may occur on area streams and
  significant flooding may occur in low lying and poor drainage

precautionary/preparedness actions...

a flash flood watch means that conditions may develop that lead
to flash flooding. flash flooding is very dangerous. monitor the
forecast and be prepared to take action if you see rising water
or if flash flood warnings are issued.
