That's what one electronic road sign said in Casper on Saturday. The Wyoming Department of Transportation says a sign operator working from Cheyenne meant to type "35+" but mistakenly added another 5.
A local newspaper reports that the inflated wind gust message was posted for 17 minutes before the department noticed the mistake and corrected it.
The whirlwind on social media lasted longer.
One person posted a photo of the sign with the comment "CASPER WY. WHERE TORNADO ALLEY SEEMS PLEASANTLY BREEZY."
