The monsoon has finally arrived in Colorado. But as desperately as we need the rain, it is causing problems. With huge, fresh burn scars in the mountains, we are now getting a lot of flash flood warnings in and near the canyons. A highway through the High Park burn area had to be closed yesterday because of mudslides, and residents in one canyon, who had already evacuated twice for the fire, were put on pre-evac notice for flooding. Experts say it could be as long as five years before the scarred slopes recover enough to stop being a flood and mudslide hazard.
