PAGOSA SPRINGS, Colo. – A surge of deep subtropical moisture is targeting southwest Colorado tonight through early Sunday, bringing a high risk of flash flooding across the Eastern San Juan Mountains. The heaviest rainfall is expected on west-facing slopes, where 2 to 4 inches of rain could fall in less than 36 hours, threatening travel along U.S. 160 and mountain passes including Wolf Creek and Cumbres.
According to the National Weather Service in Pueblo, a Flash Flood Watch remains in effect through early Sunday morning for the Eastern San Juans and the Upper Rio Grande Valley. The combination of steep terrain, saturated soils, and locally intense downpours could trigger rapid runoff and debris flows along creeks and burn scars. Motorists and hikers are urged to avoid low-lying crossings and steep drainages during periods of heavy rain.
Emergency managers warn that even normally dry washes may flood quickly. Residents in flood-prone areas should prepare to move to higher ground if warnings are issued. Travelers planning to cross the Continental Divide late tonight or Saturday should monitor CDOT alerts for possible closures or rockfall hazards.
Forecasters expect rainfall to taper before sunrise Sunday as the moisture plume exits eastward, but lingering showers may persist near the Divide. Cooler, drier weather is forecast to return by early next week, offering some relief after a wet weekend.
