due to much warmer and drier conditions. Winds will be gusty on
Saturday especially over higher terrain. East winds around 15 to

.HYDROLOGY...
Recently received snowfall present in the Brooks Range / North Slope
area along with warming temperatures will promote snowmelt,
giving the potential for high water for the Colville, Sag, and
Kuparuk rivers and their tributaries. There are some ice jams
present on the Colville, which will enhance any flooding threat.
Water levels are expected to crest by the end of this week into
the weekend. The water level in Fort Yukon will continue receding
very slowly. Satellites and ground observations continue to
indicate plenty of snow in the Porcupine Mountains. As
temperatures continue to warm over the next few days, snowmelt
could lead to continued high water for streams in that area.
