Spotter Training This Week

Temperatures will continue to increase along with elevated fire danger through Memorial Day and Tuesday, bringing near record highs up to 100°. Take action to stay cool and prevent sparks while recreating the next few days, particularly on Tuesday with gusty southeast winds up to 45 mph expected and isolated evening thunderstorms.

Here's a reminder that we have TWO virtual spotter training opportunities coming up. Anyone is welcome to attend any session. The session on Thursday will focus on severe weather along the Hi-Line. Make sure to register to receive more information and a link to the virtual class.
