UPDATES FROM THE PREVIOUS SPRING BREAKUP OUTLOOK

We are at the midpoint of the spring breakup season. Mild
temperatures and greater overall cloud cover have worked to delay
breakup and reduce flood impacts so far by slowing ice and snow
melt. The overall breakup flood threat is trending near normal. As
we look into the next few weeks, temperatures are expected to remain
mild. The the things to watch:

Middle and Lower Yukon River: Breakup has progressed to Ft Yukon.
temperatures so far have been below-to-near normal, but this week
they are expected to have lows above freezing for the first time
this spring. Hydrologists will be watching to see how the breakup
front from the Upper Yukon impacts the in-place ice on the middle
and lower river.

Lower Kuskokwim River: The breakup front is at Aniak, and
hydrologists will monitor how the breakup front from the upper river
will impact the yet untested ice on the Lower Kusko.

North Slope: Breakup and snowmelt have not yet begun. Snowpack
remains normal-to-above normal.

Flooding and ice jams so far this spring have occurred on the Black
River at Chalkyitsik, the lower Chatanika near Minto, Fish Creek
near Anderson, and the Kuskokwim River at Aniak.

STATEWIDE FLOOD POTENTIAL OVERVIEW

The breakup flooding potential is normal across most of mainland
Alaska. With the Upper Yukon and Kuskokwim Rivers broken up, the
remaining areas of concern are the Lower Yukon, Lower Kuskokwim, and
the North Slope.
