316 PM HST Fri Feb 26 2021

...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH SUNDAY AFTERNOON...

The Flash Flood Watch continues for

* Maui and the Big Island.

* Through Sunday afternoon

* A persistent trough aloft will bring the potential for a
  prolonged period of rainfall to windward portions of Maui and
  the Big Island. Increasing ground saturation from repeated
  heavy rain bands will produce an increasing threat for flash
  flooding through the weekend.

* Flood prone roads and other low lying areas may be closed due
  to elevated runoff and overflowing streams. Landslides may
  also occur in areas with steep terrain.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Be prepared to take action if a Flash Flood Warning is issued. If
you experience heavy rain or rising waters, head to higher ground
immediately.

A Flash Flood Watch means that conditions are favorable for flash
flooding. Flash Flooding is LIFE THREATENING. Do not cross fast
flowing water in your vehicle or on foot.
