Hydrologic Outlook issued May 9 at 7:43AM MDT by NWS Albuquerque NM

ESFABQ Risk of areal flooding and elevated stream flows from rapid snowmelt ...EXISTING CONDITIONS... Recent storms have brought several inches of snow to mid to high elevations (8500'->10500')over the Sangre de Cristo, Jemez and Tusas mountains throughout north central New Mexico. This snow pack contains on average 3-5 inches of liquid equivalent. With upcoming precipitation and warming temperatures, this region of New Mexico is vulnerable to flooding from rapid snowmelt. ...PRECIPITATION... There is a 50% chance of 0.5" of rainfall over much of the region of concern today (5/8) from noon to 7pm MDT. There is a 10% chance that

ESFBYZ Warm temperatures are forecast through early next week. This will enhance snowmelt across area mountains, resulting in a significant increase in flows on area rivers and streams by this weekend. While flooding is not anticipated on larger rivers and streams, there is a chance that some smaller streams could reach bankfull in and near the foothills, producing minor flooding. At the very least, stream flows will be much higher with the increased snowmelt. Water rises will occur first on small streams flowing out of the foothills, eventually arriving on larger rivers and streams. The rate and magnitude of the

ESFGJT Risk of areal flooding and elevated stream flows from rapid snowmelt ...EXISTING CONDITIONS... Recent storms have brought several inches of new snow to mid to high elevations (8500' to 10,000') over the San Juans mountains, nosing along the Divide across Central Colorado. With forecast temperatures running 5 to 15 degrees above normal and the potential for showers and storms along the Divide each afternoon through the weekend, this region of western Colorado is vulnerable to enhanced runoff and elevated stream flows from rapid snowmelt. ...PRECIPITATION... Isolated to scattered showers and storms developing each afternoon favor high terrain across the

ESFPUB Risk of enhanced runoff and elevated stream flows from rapid snowmelt ...EXISTING CONDITIONS... Recent storms have brought several inches of snow to mid to high elevations (8500'->10500') over the eastern San Juan and Sangre de Cristo Mountains of south-central Colorado, and along the Continental Divide of central Colorado. With upcoming precipitation, warming temperatures, and possible rain-on-snow for mid to high elevations, this region of Colorado is vulnerable to enhanced runoff and elevated stream flows from rapid snowmelt. ...PRECIPITATION... There is a roughly 35% chance of 0.1" or more of liquid precipitation over much of the area of concern later

ESFAFC As of late Thursday afternoon, heavy floes of ice are working their way downstream on the Kuskokwim River from near Bethel to Napakiak. Water levels are high to near bank full as these runs of ice move downstream; however, flooding is not anticipated as downstream ice has been rapidly weakening over the past several days down to the mouth of the Johnson River. Per observation, area sloughs and Kuskokwim River tributaries are also taking some of the ice to relieve stress on the Kuskokwim. NWS and the River Watch team will continue to reach out to local community members

ESFAFG The Yukon River at Ft. Yukon broke up Tuesday with minor flooding from an ice jam that released overnight into Wednesday morning. The breakup front remained stalled at 6 Mile Island below Ft. Yukon as of early Wednesday afternoon while water levels have continued to drop at Ft. Yukon. The water that has been carrying the breakup front has continued downstream and is helping to lift and shift the ice between Ft. Yukon and Beaver; however without a pulse of water from upstream breakup may be slowed for a few days. The timing of the breakup front reaching Stevens
