URGENT - FIRE WEATHER MESSAGE
National Weather Service Denver/Boulder CO
705 PM MST Sun Mar 5 2017

...VERY HIGH FIRE DANGER THROUGH MONDAY...

.Cooler temperatures and higher humidities have brought slight
improvement to the fire danger this evening. However, it remains
quite dry and breezy, especially across Douglas and Elbert
counties, and so the fire danger does remain elevated.

A strong cold front will move through around sunrise, followed by
west to northwest winds gusting as high as 60 mph. Humidities will
remain low, creating extreme fire danger across all of eastern
Colorado during the day Monday. 

Residents should postpone any planned burning and avoid activities
that could create sparks or otherwise start fires. Fire agencies
should be prepared for the possibility of rapidly spreading
wildfires.
