East Wilson Weather

The National Weather Service in Portland has issued a Red Flag
Warning for thunderstorms, which is in effect from noon to 9 PM
PDT Wednesday. The Fire Weather Watch is no longer in effect.

* AFFECTED AREA...In Oregon, Fire Weather Zone 688 Mt. Hood
National Forest Region.

* THUNDERSTORMS...A 15 to 20% chance of dry thunderstorms. Storms
may produce very little rainfall, increasing the risk of new
fire starts from dry lightning.

* OUTFLOW WINDS...Instantaneous gusts as high as 40 mph. Gusts at
these speeds can be observed tens of miles away from the core of
the thunderstorm.

* DRY AND UNSTABLE...Unstable conditions with elevated mixing
heights may promote pyroconvective activity over ongoing fires.

* IMPACTS...Conditions may be favorable for rapid fire spread
which may threaten life and property. Thunderstorm outflow winds
may result in unanticipated erratic fire spread. High
instability may result in fire growth. Frequent lightning and
critically dry fuels may result in new fire starts.

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