...PUBLIC INFORMATION STATEMENT...

...DOWNBURST CONFIRMED IN MARION COUNTY WV...

Widespread damage reported yesterday afternoon (Aug 8, 2019) in
Marion County WV has been confirmed to be the result of a
downburst that occurred near Farmington and Fairmont.

A downburst occurs when cold air high in a thunderstorm descends
and accelerates. As the stream of cold air reaches the ground, it
spreads out and can accelerate further.

When environmental conditions are favorable, wind in a downburst
can exceed 70 to 80 mph. Such wind is comparable to, or stronger
than, many tornadoes and can cause similar damage.

Damage reported in Preston County near Bruceton Mills also was
caused by straight-line thunderstorm wind.

The National Weather Service office in Pittsburgh appreciates all
reports and information that have been provided to us about these
storms.
