Red Flag Warning
URGENT – FIRE WEATHER MESSAGE
National Weather Service Denver/Boulder CO
346 AM MDT Wed Aug 19 2020

.Moisture levels over northern Colorado are expected to increase
today 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 today, 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.
