Experiment: Wind Chill Warnings will be replaced by Extreme Cold Warnings
The past criteria for windchill headlines:
- Wind chill advisory: Wind chills -25º to -39º.
- Wind chill warning: Wind chills -40º and colder.
The new threshold for this winter:
- Extreme Cold Warning: air temperature or wind chill value below -35º.
I like the idea of illustrating how the human body needs extra protection from bitter cold, whether there is a wind or not, and that threshold for this part of the world has been placed at -35º.
However, I can see some confusion, especially since this change doesn't seem to have been broadcast widely enough.
The bottom line reinforced by this change is that
BITTER COLD = DANGER
So keep an eye out for the new Excessive Cold Warning headline this winter!
As a reminder, here is the chart showing how the lower the temperature and the higher the winds, the less time it takes for exposed skin to freeze.

Great to see you back in action, N! I wonder if we'll get to use that chart soon...
ReplyDeleteYou're always on the ball :)
ReplyDeleteActually, I really don't want to think about the 'blue chart'. But with -60s and -70s in the Yukon, Siberia, and Greenland... it's only a matter of time. But we knew that already, right?
