Hydrologic Outlook issued May 10 at 3:51PM 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 2-4 inches of liquid equivalent. With warming temperatures expected over the next 48 hours, these regions are vulnerable to flooding from rapid snowmelt. ...Temperatures... There is a greater than 50% chance of temperatures greater than 68-70 degrees over the snowpack. These temperatures along with the relatively high sun angle observed in mid may

ESFGJT Risk of areal flooding and elevated stream flows from rapid snowmelt ...OVERVIEW... Mid to high elevations (8500' to 10000') along the San Juan Mountains and along the Divide through central Colorado are susceptible to enhanced runoff and elevated stream flows from rapid snowmelt. ...TEMPERATURE... High temperatures will continue to run 5 to 10 degrees above normal through the weekend, with overnight lows remaining above freezing for mid to high elevations. This warming trend carries into Monday, resulting in highs climbing 10 to 15 degrees above normal. Said departure from normal increases from south to north. ...PRECIPITATION... Isolated to scattered

Hydrologic Outlook issued May 9 at 3:07PM AKDT by NWS Fairbanks AK

ESFAFG As of Friday afternoon, ice and water continues to flow past Galena, even though there is still some in-place ice slowing it down above Pilot Mountain Slough. There are a few more short in-place sections of ice between Galena and Nulato that should not cause any significant jamming concerns. Below Nulato, the river ice remains in-place with signs of lifting and thermal degradation. The Yukon is open from Galena upstream to the Nowitna River with the exception of a small (
