Rainfall Expected Description:
An area of Low Pressure over the Gulf of Alaska will move into Interior
Alaska tonight and remain nearly stationary through Thursday. Bands of
moisture rotating around the Low Pressure area will spread into the Central
Interior and result in significant rainfall beginning tonight and continuing
into Thursday. The heaviest rain is expected from the uplands North and East
of Fairbanks to the Alaska Range. Rainfall amounts of 1 and 2 inches is
likely over much of this area, with higher amounts exceeding 3 inches
possible in the mountainous terrain. There is still some uncertainty where
the heaviest rain will fall, but significant rises on streams and rivers
across this region are expected Wednesday through Friday. Some streams and
rivers may reach bankfull and it is possible that water may glow overbank in
some locations. People along rivers draining the uplands North and East of
Fairbanks such as the Chena, Chatanika, and Salcha Rivers should prepare for
rising river levels and increased debris moving downstream. In addition,
streams and rivers in the Alaska Range from Denali National Park East to the
Richardson Highway will likely see significant rises as well. Additional
statements regarding this event will be issued as the confidence in the
rainfall amounts and location of the heaviest rainfall improves.
