...HYDROLOGIC OUTLOOK FOR THE BROOKS RANGE AND NORTH SLOPE...

...Locations Impacted...
Western Arctic Plains-Romanzof Mountains-Central Arctic
Plains-Central Beaufort Sea Coast-Howard Pass and the Delong
Mountains-Eastern Beaufort Sea Coast-Central Brooks Range

Summer is expected to finally arrive in the Brooks Range and on the
North Slope.  Near normal temperatures, which include above freezing
overnight temperatures, are predicted as we enter next week.

Most of the remaining snowpack is in the foothills and mountains
where temperatures will be highest. This could lead to rapid melt
and river rises.

Most of the ice on the larger rivers has already moved out which
leaves more room to accommodate the increasing snowmelt.  This
contrasts with last year`s late breakup when the snowmelt all
entered the river systems while ice was mainly still in place.

Rising and water levels in rivers can be expected as this melt is
initiated and moves through the river systems this weekend and into
next week.
