“Fire Weather” – Minnesota’s new favorite weather term!
Sometimes it’s hard to say if a unusual “weather” pattern is becoming a more frequent “climate” trend.
Fire Weather Watches? Again? For Minnesota?
Am I writing/broadcasting for MPR’s vast news network about an unusual weather pattern…or a developing climate trend? Are the weather maps I’m looking at an aberration…or am I witnessing Minnesota climate change right before my very eyes?
You could certainly make the case that increased use of “Fire Weather” and “Red Flag” watches and warnings in Minnesota lately is part of a trend…a shift into a hotter and potentially drier climate.
Whatever the “big picture” answer is…the latest “Fire Weather Watch” is here for western Minnesota.

You can see “high” or “very high” fire danger blankets Minnesota from the metro north now. What does it mean?
Fires start easily and spread at a fast rate. All fine dead fuels ignite readily and fires start easily from most causes. Unattended campfires are likely to escape. Fires spread rapidly and short-distance spotting is common. High-intensity burning may develop on slopes, or in concentrations of fine fuel. Fire may become serious and difficult to control unless they are hit hard and fast while small.
Fires start very easily and spread at a very fast rate. Fires start easily from all causes, spread rapidly and intensify quickly. Spot fires are a constant danger. Fires burning in heavy fuels may quickly develop high-intensity characteristics, such as long-distance spotting and fire whirlwinds. Direct attack at the head of such fires is rarely possible after they have been burning more than a few minutes.
As you might expect…burning restrictions are in effect.
