I used to live in Longmont. I was the Assistant District Forester for Boulder County. Maybe you've seen the picture of Lefthand Creek flowing across the highway. That's CO-72. The road to my old office can be seen on the left side where the white van is parked. I've been checking out the online pictures. I know many of those places. I even saw a woman from the same church I used to belong to; she was drying out some of her stuff that got flooded. This is all hitting too close to home.
The Weather Service is saying that this is a 500-year flood. The last major flood to hit that area was Big Thompson in 1976. In 1921 Boulder Creek put about ten feet of gravel in downtown Boulder. Store owners simply took the top of their buildings and put new doors in what used to be the second story. Some of those buildings in Boulder have double-decker basements.
Floods in that area tend to be associated with rainstorms in the mountains, especially slow-moving storms that just sit in one place and dump rain. This is an unusually large event, but whether it has anything to do with warming is an open question.
I completely agree.
As I wrote somewhere earlier in some post above, its to early to conclude if this just weather or cc. However by looking at the data, my opinion is that its just weather and not CC. This is why I am a bit choked that some scientists have already been out the in the media saying "Yup, this is because of Global Warming" They shouldn't be saying this as its misleading the public. If they however said, its my opinion that this is due to climate science, then I wouldn't have a problem at all.
I understand it must be scary seeing all this "so close to home" Especially an extreme event like this.
Didn't know about the double basements story, quite interesting when you think about it. Thanks for that.
