2019 FLOOD SEASON IS HERE 

EXECUTIVE SUMMARY 

- Colorado statewide snowpack as of May 30 is at 432% of normal for this date. All basins with the exception of the North Platte, South Platte, and Yampa/White are over 350% of average for this date. 

- Widespread, regional snowmelt flooding is not common for Colorado. However, isolated flooding and extended periods of high water are likely to occur this season. 

- Numerous watersheds have volumetric forecasts over 130% for the runoff season. It can be implied that these will have the most elevated risk for snowmelt flooding. These watersheds include: Blue, Upper Arkansas, entire Gunnison River basin, Dolores, San Miguel, Mancos, La Plata, Animas, Upper Rio Grande, and Saguache/San Luis 

- Extended forecasts have been released. The remainder of May is expected to be cool and wet for the entire state. The forecast for June indicates a wet month for the entire state, with cooler than normal temperatures on the Eastern Plains. The June forecast will be updated on May 31. 

- Snowmelt has significantly slowed down during the second half of May. This may result in a heightened risk of snowmelt flooding in June.
