2008 Riverwatch Program
DHS&EM deployed Riverwatch Field Team continues river watch of the upper Yukon.  This morning they were at the Village of Circle and reported a minor flooding that had occurred.  They are now covering the vicinity of the Yukon-Charley National Park on their way down river to Fort Yukon.

Our second team is deploying tomorrow traveling to Aniak.  This team will be making their aerial reconnaissance along the Kuskokwim River. Initial surveillance will concentrate on the area between Aniak upstream to Stony River.

This program monitors the breakup of major rivers in Alaska and warns residents along those rivers of potential flooding from ice jams. The 2008 Spring Flood Breakup Guide is posted on our website at http://www.ak-prepared.com/

Flood warning/watches:
The National Weather Service in Fairbanks has issued a flood advisory for ice jam flooding for the Yukon River at Circle until 12:00 pm Thursday.  An ice run arrived at Circle Tuesday night and jammed up enough to cause flooding in low lying areas in Circle. Water has backed up into the most floodprone areas of Circle. This includes a low portion of the road between the airport and the town. Water levels have declined a foot from the peak early today, Wednesday morning. The ice below Circle did not appear to be very strong prior to the jam and thus the jam is not expected to hold very long.

The National Weather Service in Fairbanks has issued a flood statement for the Middle Tanana Valley, Deltana and Tanana Flats:
The flood warning remains in effect until 2:00 pm Thursday for ice jam flooding on the Tanana River in the Salcha area from the mouth of the Salcha River to Old Valdez Trail. Several ice jams have formed on the Tanana River between the mouth of the Salcha River and the Boondox area. An ice jam approximately one mile downstream of the mouth of Salcha River has shifted and water levels on the Tanana River are dropping in and around the Starkeyville Subdivision. Water has dropped several feet since Wednesday morning. A second ice jam one half mile downstream of the Boondox area has shifted and water from the Tanana River has backed out of the Piledriver slough. Piledriver slough is back in its banks and the Old Richardson Highway is no longer flooding. However, small ice jams still exist and water levels may fluctuate until all jams have released and ice in the Tanana River has flushed downstream.

The National Weather Service in Anchorage has correction to a flood advisory.  Flood advisory for ice jam flooding on the Gakona River at the Tok cutoff in Copper River basin until 2:45 pm Wednesday.  At 2:45 pm a significant ice jam has formed from just below the highway bridge all the way down to the Copper River confluence. Expected impacts:  Water has backed up behind the ice jam and has risen to a level that is causing flooding of the school road and some private property. Access to the school is extremely limited.  Water levels are fluctuating as the water finds its way around the jam.

Alaska Spring Breakup Summary
The NWS Alaska-Pacific River Forecast Center in Anchorage has issued the current flood potential from snowmelt and ice jams this spring breakup season is currently rated as above average for southeast Alaska and the Seward Peninsula.  It is rated as average for the Copper, western Susitna, Kenai, Kuskokwim and Koyukuk River basins.  The flood potential is below average for the remainder of mainland Alaska.  This forecast is based on observed snowpack, ice thickness reports and long range temperature forecasts.

Red Flag Warning
The National Weather Service in Anchorage has issued a red flag warning for Matanuska Valley which is in effect from 2 pm this afternoon to 10 pm this evening for strong wind. A ridge along the north gulf coast combined with a thermal trough in the Susitna Valley will cause southeast wind gusts to 30 mph to develop this afternoon and remain through much of the evening. In addition, relative humidities are expected to drop to 25 to 30 percent this afternoon and not recover until later this evening.
