A high threat of flash flooding remains for Archuleta, Hinsdale and Mineral counties and the immediate surrounding areas; a moderate threat is forecast for parts of Southwest Colorado and a low threat forecast along the Continental Divide.
The most monsoonal precipitation is forecast along the Colorado and Utah border and in the far southwestern corner of Colorado.
