REF: General-MSR 90
Wind Chill Chart
- Numbers are based off the latest wind chill data from the National Weather Service. 1)
- Wind speed on the left of the column has been updated to reflect speeds up to 90 mph using the National Weather Service “Wind Chill Calculator”. 2)
- All wind chill numbers have been rounded to the nearest whole degree.
- Numbers do not take into account sustained natural wind speed or crosswinds which will lower the final wind chill number slightly.
- Highlighted (-) number shown at beginning danger zones (frost bite within 30 minutes exposure).
