ESFAFG ...Locations Impacted... Central Brooks Range-Central Arctic Plains-Romanzof Mountains-Central Beaufort Sea Coast-Howard Pass and the Delong Mountains-Western Arctic Plains-Eastern Beaufort Sea Coast Summer has arrived in the Brooks Range and on the North Slope. Warmer temperatures including above freezing temperatures overnight are expected through early next week. Additionally, rainfall amounts ranging from 0.5 to 1.0 inches are now expected between Sunday night and Wednesday morning. Most of the remaining snowpack is in the foothills and mountains where temperatures and rainfall will be highest. The combination of snow melt and rainfall is increasingly likely to result in river rises. Most of the ice on the larger rivers has already moved out which leaves more room to accommodate the snowmelt and rainfall. This contrasts with last year's late breakup when the snowmelt all entered the river systems while ice was mainly still in place. Rising water levels in rivers can be expected as this melt is initiated and moves through the river systems this weekend and early next week.
