RED FLAG WARNING THROUGH SATURDAY AFTERNOON FOR MAINLY LEEWARD
AREAS DUE TO WINDY CONDITIONS AND LOW HUMIDITY...
.Dry and windy conditions will persist as high pressure moves
east and strengthens north of the islands. After a brief period of
increased moisture tonight, another pocket of drier air will move
into the region again on Friday, and could continue for at least
portions of the state into Saturday. Highest confidence in Red
Flag conditions will be for Friday from late morning through the
afternoon hours, when lowest relative humidity values coincide
with the strongest expected wind speeds.
Affected Area:
Leeward portions of all Hawaiian Islands,
including interior sections of Oahu and the Big Island and all
of North Big Island.
Timing:
Until 6 PM HST Saturday. The main fire weather concerns
will be Friday from late morning through the afternoon hours
when relative humidity is lowest. It is possible that dry and
windy conditions will persist to include Saturday as well.
Winds:
For Friday, east winds 20 to 35 mph with gusts up to 55
mph. On Saturday, east winds 15 to 25 mph with gusts to 35 mph.
Relative Humidity:
As low as 40 percent.
Impacts:
Any fires that develop will likely spread rapidly.
Outdoor burning is not recommended.
Instructions: A Red Flag Warning means that critical fire weather conditions
are either occurring now or will shortly. A combination of strong
winds, low relative humidity, and warm temperatures can
contribute to extreme fire behavior. A Red Flag Warning does not
predict new fire starts.
