URGENT - FIRE WEATHER MESSAGE
National Weather Service Spokane WA
112 PM PDT Tue Jul 16 2024

Scattered thunderstorms containing little to no rainfall will be
possible over much of North Central Washington Wednesday
afternoon and evening. Any thunderstorms have the potential to
produce gusty outflow winds that could travel quite a distance
from the thunderstorm source. Isolated thunderstorms are possible
elsewhere across Eastern Washington and North Idaho.

/O.NEW.KOTX.FW.W.0006.240717T1900Z-240718T0700Z/
Western Columbia Basin (Zone 707)-Eastern Columbia Basin -
Palouse - Spokane Area (Zone 708)-
112 PM PDT Tue Jul 16 2024

...RED FLAG WARNING IN EFFECT FROM NOON WEDNESDAY TO MIDNIGHT
WEDNESDAY NIGHT FOR HOT DRY AND UNSTABLE CONDITIONS AS WELL AS
GUSTY OUTFLOW WINDS FOR THE COLUMBIA BASIN INTO THE PALOUSE AND
SPOKANE AREA...

The National Weather Service in Spokane has issued a Red Flag
Warning for thunderstorms, which is in effect from noon Wednesday
to midnight Wednesday night.

* Affected Area: Fire Weather Zone 707 Western Columbia Basin
  and Fire Weather Zone 708 Eastern Columbia Basin - Palouse
  -Spokane Area.

* Haines: High level haines of 6, which is very high. This means
  very dry and unstable conditions exist.

* Humidity: 12 to 19 percent.

* Outflow Winds: Gusty and erratic winds are possible with any
  thunderstorms that develop. Gusty winds from thunderstorms that
  develop over the Cascades and north central Washington could
  send an outflow boundary across the Columbia Basin, Palouse and
  Spokane area.

* Thunderstorms: Thunderstorm coverage at this time looks to be
  isolated across the Basin, Palouse and Spokane area.

* Impacts: Unstable conditions could lead to plume dominated
  fires. Rapid fire spread with any new or existing fires due to
  the gusty wind potential. These conditions may overwhelm
  initial attack capabilities.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Red Flag Warning means that critical fire weather conditions
are either occurring now....or will shortly. The weather
conditions mentioned above can contribute to extreme fire
behavior.
