4th Blowdown

With recent Memorial Day severe thunderstorm is still fresh in our minds, it is a good time to point out that we have had similar storms before.  Early in the morning of July 4 of 1999, at 7:30 in the morning, a strong downburst wind hit the area with tremendous force.

At Hector Airport, the wind storm lasted for 38 minutes with winds measured as high as 91 mph.  Damage in the Fargo area was estimated at 85 million dollars (1999 dollars) and several people were injured.  The storm then evolved into a powerful straight-line wind storm which moved rapidly northeastward across northern Minnesota.  With winds between 80 and 100 mph, the storm destroyed some 10 million trees in the Boundary Waters Canoe Area.

Sixty campers in the BWCA were injured by the falling trees and many had to be rescued by float plane.  The storm continued across Ontario and Quebec before finally weakening over western Maine on July 5.

The storm is known in weather lore as the ?Boundary Waters Blow Down.?

  1. Those big storms can be dangerous for sure. I’ve always thought that a stormy camping trip can sometimes be memorable, but when it really turns severe it can be life threatening, even if you’re not camping. Hope you had a good fourth!

  2. Weather was great on the 4th, until, well, evening. A few severe cells (not a good camping evening). In Fargo it was just a generic thunderstorm, but not the case for all sadly. Robert, I hope you had a good 4th. :-)
