It doesn't look as if it will take very much more moisture or snowmelt to bring these waterways out of their banks. To their credit, Mesa County and the various municipal and public safety entities that serve these areas appear to be closely monitoring these conditions, and by my own knowledge and the local media accounts, are as prepared as they can be.
With the local forecast showing a pretty good chance for rain and/or snow over the next few days, vigilance and flexibility are two of the keywords that define how life is going to be for those who live, work, or travel through these areas.
I've seen my share of flash flooding and what it can do, especially to vehicles and the people in them. You can see a good example and reminder here.
Be safe out there.
