Grand Junction, CO – Heavy snowstorms over the San Juans mountains and the Divide across Central Colorado have set the stage for a heightened flood risk in the coming days. According to the National Weather Service (NWS) in Grand Junction, rapid snowmelt, combined with afternoon showers and storms, is expected to elevate stream flows and cause localized flooding through the weekend.
The NWS notes that temperatures in the region are forecast to be 5 to 15 degrees above normal, intensifying the snowmelt process. Rainfall amounts will remain light, between 0.1 to 0.2 inches, but rain on snow could amplify the snowmelt rates, further contributing to the risk of flooding in low-lying areas, particularly at elevations between 8,500 and 10,000 feet.
Streams and rivers across the southwestern San Juans and the Divide are forecast to see rapidly rising, dangerously cold waters. The NWS warns that these elevated flows could lead to localized inundation, particularly near mountainous terrain where streams may swell unexpectedly.
Residents and travelers in these areas are urged to avoid fast-moving water, stay clear of riverbanks, and exercise caution when near streams. This hydrologic outlook is expected to remain in effect until May 10, with more updates likely depending on storm activity and snowmelt progression.
