URGENT - FIRE WEATHER MESSAGE
National Weather Service Medford OR
842 PM PDT Wed Sep 8 2021

...Scattered Thunderstorms on Dry Fuels Thursday Afternoon Into 
Friday Morning...

.Southwest winds will be gusty and strong again east of the
Cascades on Thursday afternoon as an area of low pressure moves 
towards the region. This low will bring a chance for showers and 
thunderstorms from the Cascades eastward from Thursday afternoon 
into Friday morning. During Thursday afternoon and evening, 
thunderstorms will have elevated bases which will result in strong,
gusty downdraft winds and little or no precipitation. Later 
Thursday night into Friday morning, the air mass will moisten with 
a change to more numerous, mostly wet storms. The region of showers
and thunderstorms will gradually shift northeast out of the area 
later Friday, with the risk of thunderstorms lingering longest for 
northern portions of Klamath and Lake counties.

  Despite rainfall, initial attack resources could be overwhelmed and   
  holdover fires are possible. In addition, gusty winds and
  dry humidities on Thursday afternoon along with gusty winds within

  to the spread of any new fires.

* Affected area:

  afternoon and evening, this includes Warner and Hart Mountains, 
  Winter Rim, portions of the Fremont National Forest and BLM land in

Familiarize yourself with your evacuation plan. Where will you go?
How will you get there? Who will you call to let others know your
are safe? Visit ready.gov/wildfires for more information.

A Red Flag Warning does not mean there is a fire. It means that
critical fire weather conditions are either occurring now or will
shortly. These conditions promote rapid spread of fire which may
become life threatening. Evacuate if ordered to, or if a fire
threatens.
