Once in a while, the jetstream hits a Colorado mountain peak and dips straight down into Boulder, always from the West. I made the mistake of facing my schoolie directly into the wind (due West). I say that was a mistake because there was enough sand in the wind that it sandblasted my windshield! *Dang* Seeing though the glass after that wasn't too bad in the day, but caused blur and glaring at night that made it hard to drive safely. So my advice is to face your vehicle directly away from the wind, not into it, because a sandblasted rear window will not be much of a problem.
I had told my parents about the wind being over 200 mph, and my father admitted he didn't believe me. So I didn't tell my family when it happened again when there was a trailer part straight to the west of us. The sheriff had evacuated everyone from the park before the wind began blowing the guts of the smashed trailers our way. The park was destroyed, and I felt like we were with Dorthy in a "Wizard of Oz" as furniture (and everything else) came sailing by us as we watched out the side windows. Even a complete RV bathtub sailed right by our door! A couple of days later, I got a letter from my family in Texas that my father had heard in the Paul Harvey News Hour over his car radio while driving to work, that winds of 235 mph had sailed through Boulder. IT TOOK A NEWS ANNOUNCEMENT FROM PAUL HARVEY FOR MY OWN FATHER TO BELIEVE ME! *dang*
They don't announce wind speed from Boulder anymore as the local government concluded it was hurting tourism, new business growth, and home construction. But it only happens once every few years. Another time when it happened I was walking down the street when someone else on the sidewalk yelled "Holy Cow!" I looked up to see what it was about, just in time to see the first wave of this wind coming over the top of Green Mountain from the far side. Very impressive, much like ominous dust storm pictures you sometimes see online. I was most impressed by how fast it was rolling down the mountainside toward us! (200+ mph is pretty fast.)
A funny part: Naturally, we had to let our dog out to pee. But she kept getting blown over and rolled over and over. Then she'd stand up, only to get blown over and rolled again! Ha hahaha! I'm not sure she ever managed to pee.
