URGENT - FIRE WEATHER MESSAGE
National Weather Service Denver/Boulder CO
1241 PM MDT Wed Aug 19 2020
.Moisture levels over northern Colorado are expected to increase
today and Thursday which will cause the chance of thunderstorms
over the high country to also increase. Fuel moisture levels are
very low in the mountain areas due to a lack of precipitation over
the past several weeks. Recent forest fire activity in Larimer
and Grand Counties demonstrates how dry the forests are. As the
chances of thunderstorms increases each afternoon, the chance of
lightning starting additional fires will also increase. The main
impact from showers today will be gusty outflow winds from 30 to
50 mph possible.
