KTIV Meteorologist Beverly Perry SHARES history and information about high wind warnings

Posted:

Trash cans blown about and traffic signs whipping in the wind are just a few signs of how strong the wind can be, and why the National Weather Service issued a high wind warning.

"What we're looking at is a period of time where winds are going to be sustained above 30 or gusts of 45 to 50 miles per hour," says Todd Heitkamp, Warning Coordinator.

But how do those gusts compare to other weather events such as a tornado or a hurricane? An EF0 tornado has winds of 40-72 mph and a Category 1 hurricane has winds of 74-96 miles per hour. So while it's not hurricane level, Thursday's winds could be considered similar to a severe summer storm.

"A lot of our high wind warnings are associated with summer convection which in other words, thunderstorm activity. Most of the time during the winter time we will issues high wind advisories but high wind warnings are somewhat rarer than what advisories are."

A high wind warning is not common but it has happened before. The last high wind warning was issued for Siouxland in October of 2012. The last time that we saw winds this high in the month of January was in 2005. Looking back to 1973, we had 4 other day that had wind gusts of 60 miles per hour or greater.
