Alamosa, CO – Major river flooding is forecast to continue across portions of southern Colorado's San Luis Valley Monday, November 2, with several waterways expected to remain above flood stage for days as another round of unsettled weather brings showers and strong winds to the region.
According to the National Weather Service in Pueblo's November 1 evening river forecast, the Rio Grande, South Fork Rio Grande and Conejos River are expected to experience flooding, with conditions progressing eastward toward Alamosa.
Major Flooding Threatens San Luis Valley The NWS forecast indicates major flooding along the Rio Grande at Del Norte and Monte Vista, with river levels expected to remain above flood stage until Tuesday evening and Wednesday morning, respectively.
Major flooding is also forecast along the South Fork Rio Grande at South Fork and the Conejos River near Mogote.
Farther downstream, the Rio Grande at Alamosa is projected to reach minor flood stage Tuesday at approximately 11 p.m., with levels potentially remaining elevated until Friday morning.
Residents should watch for flooded roads, low water crossings and rapidly changing river conditions, particularly near the affected waterways.
Strong Winds Add to Monday's Weather Concerns Meanwhile, a separate NWS Pueblo forecast calls for widespread wind gusts between 30 and 50 mph across Colorado's eastern Plains Monday.
Temperatures are expected to reach the 50s and 60s at lower elevations, while mountain communities remain cooler, generally in the 30s and 40s.
Showers will continue across western and mountainous areas, with high elevation snow possible as precipitation spreads eastward.
The combination of flooding, wet roads and gusty winds could complicate travel across affected portions of southern Colorado.
Motorists should never attempt to cross flooded roadways, and residents near rivers should monitor updated forecasts and local emergency notifications.
