  erratic and gusty winds. Spotting could be problematic.

* Affected area:

shortly. These conditions promote rapid spread of fire which may
become life threatening. Evacuate if ordered to, or if a fire
threatens.

Warning...which is in effect from 2 PM to 8 PM PDT Monday. A Fire
Weather Watch has also been issued and is in effect from Tuesday

* Impacts:  Strong, gusty wind with low relative humidity and
  critically dry vegetation will greatly increase the spread
  potential of any new and existing fires. In addition, very dry
  and unstable conditions will support extreme fire behavior today.
  Plume dominated fire behavior is possible with locally-generated
  erratic and gusty winds. Spotting could be problematic.

* Affected area: In South Central OR...Southeastern Fire Weather 
  Zone 624, including the Bootleg Fire, the communities of Bly and 
  Bonanza. The Fire Weather Watch for Monday affects similar areas,
  with the addition of Lakeview and Valley Falls..

Precautionary/preparedness actions...

Avoid tossing burning cigarettes on the ground, parking hot
vehicles on dry vegetation, and using equipment that can cause
sparks. Follow all fire restrictions. Find links to restrictions
at weather.gov/medford/wildfire. One less spark, one less
wildfire.

Gather your fire evacuation kit now. Collect essentials you don't
want to lose and prioritize your checklist. Visit ready.gov/kit
for more information.

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.
