I'm surprised no one has posted anything from the area.

The biggest surprise to me wasn't that canyons have flash floods but that the bridges over the rivers down in the flats have proven to be too short.

Movement N-S thru the affected areas has been difficult as flood waters overtopped bridges that span gulleys that have been known as seeps or dry as long as anyone can remember.

Authorities have responded in well-organized ways and the police/fire/NG comms interoperability has worked really well.
Since the emergency covers so many jurisdictions mutual aid was difficult.

Agencies ran out of barriers to post to prevent people driving into overtopping waters. They also ran out of people to man barricades.

And people came out to stand on the compromised bridges and play in the water......

My long commute to/from work entirely thru the affected area will be more difficult in future. But that's peanuts compared to coworkers who lost their houses or will have to leave their houses for the winter after they are helo'd out.
