1008 AM AKDT TUE MAY 21 2013
...THE FLOOD WARNING REMAINS IN EFFECT UNTIL 1000 PM AKDT TUESDAY FOR
THE YUKON RIVER AT FORT YUKON...
THE ICE JAM 12 MILES UPSTREAM OF FORT YUKON IS CONTINUING TO BLOCK
MUCH OF THE RIVER CHANNEL CAUSING WIDESPREAD FLOODING OF LOWLANDS
UPSTREAM OF FORT YUKON. IN ADDITION THE ICE DOWNSTREAM OF FORT YUKON
IS STILL HOLDING. THIS INCREASES THE POSSIBILITY OF A RELEASE OF
WATER FROM THE UPSTREAM ICE JAM RESULTING IN A NEW JAM DOWNSTREAM OF
TOWN.
FORT YUKON IS CURRENTLY FLOODED IN LOW LYING AREAS ON THE WEST SIDE
OF TOWN INCLUDING THE BALL FIELD... THE OLD TANK FARM... THE AREA
AROUND THE TRIBAL HALL AND ONE ACCESS RAMP AT THE AIRPORT. SEVERAL
HOMES ON THE DOWNSTREAM SIDE OF TOWN HAVE BEEN IMPACTED. WHILE SOME
FLUCTUATIONS TO RIVER LEVELS HAVE BEEN REPORTED THESE DO NOT MEAN
THAT THE RISK OF MAJOR FLOODING FROM THE UPSTREAM ICE JAM HAS
PASSED. IF THE ICE JAM RELEASES SUDDENLY IT COULD RESULT IN MAJOR
FLOODING THROUGHOUT THE TOWN OF FORT YUKON. IF THE JAM HOLDS IN
PLACE LONG ENOUGH IT MAY ERODE AND ALLOW A SLOW RELEASE OF THE
UPSTREAM WATER. THIS OR THE EROSION OF ICE DOWNSTREAM OF FORT YUKON
COULD LOWER THE RISK OF MAJOR FLOODING WHEN THE ICE JAM RELEASES.
RESIDENTS SHOULD EXPECT A SIGNIFICANT RISE IN THE RIVER WHEN THE ICE
JAM RELEASES. THE FLOODING COULD BE MADE EVEN WORSE IF A NEW ICE JAM
FORMS IN THE ICE DOWN RIVER FROM FORT YUKON. THEY SHOULD ACT NOW TO
PROTECT LIVES AND PROPERTY. THEY SHOULD MONITOR THE SITUATION AND
CONTINUE TO BE ALERT FOR CHANGES IN RIVER CONDITIONS.
A FLOOD WARNING MEANS THAT FLOODING IS IMMINENT OR OCCURRING. WATER
LEVELS CAN RISE RAPIDLY AND PEOPLE ALONG THE RIVER ARE ENCOURAGED TO
MOVE PROPERTY TO HIGHER GROUND AWAY FROM THE RIVER BANK.

...FLOOD WATCH REMAINS IN EFFECT THROUGH WEDNESDAY AFTERNOON
FOR THE YUKON RIVER FROM BEAVER TO RAMPART...
THE FLOOD WATCH CONTINUES FOR
* THE YUKON RIVER FROM BEAVER TO RAMPART.
* THROUGH WEDNESDAY AFTERNOON
* THE BREAKUP FRONT ON THE UPPER YUKON RIVER WAS LOCATED JUST
UPSTREAM FROM FORT YUKON MONDAY MID AFTERNOON. THE SURGE OF
WATER AND ICE ASSOCIATED WITH THIS BREAKUP FRONT CAUSED MAJOR
FLOODING IN CIRCLE SUNDAY AND SIMILAR FLOODING IS EXPECTED IN
FORT YUKON. THE FRONT WILL MOVE THROUGH FORT YUKON MONDAY
AFTERNOON OR EVENING AND THEN CONTINUE DOWNRIVER TO
BEAVER...STEVENS VILLAGE...AND RAMPART.
* THE RIVER WATCH TEAM HAS DETERMINED THAT THE ICE FROM FORT
YUKON TO STEVENS VILLAGE APPEARS TO BE DETERIORATING... ARCHED
AND LIFTING. THE SURGE OF WATER AND ICE ASSOCIATED WITH THE
BREAKUP FRONT IS EXPECTED TO CONTINUE TO TRAVEL DOWNRIVER
STEADILY AND BECOME MORE SPREAD OUT REDUCING THE AMOUNT THE
RIVER WILL RISE. HOWEVER ANY RESISTANCE TO THE ONCOMING
BREAKUP FRONT COULD ALLOW THE WATER TO AGAIN COLLECT BEHIND AN
ICE JAM AND INCREASE THE FLOOD RISK TO DOWNSTREAM COMMUNITIES.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
A FLOOD WATCH MEANS THERE IS A POTENTIAL FOR FLOODING BASED ON
CURRENT FORECASTS.
RESIDENTS LIVING DOWNSTREAM OF FORT YUKON SHOULD MONITOR
CONDITIONS AND TAKE PRECAUTIONS EARLY TO PROTECT LIFE AND
PROPERTY. WATER LEVELS CAN RISE VERY QUICKLY WHEN AN ICE JAM
OCCURS DOWNSTREAM OF A COMMUNITY.
YOU SHOULD MONITOR LATER FORECASTS AND BE ALERT FOR POSSIBLE
FLOOD WARNINGS. THOSE LIVING IN AREAS PRONE TO FLOODING SHOULD BE
PREPARED TO TAKE ACTION SHOULD FLOODING DEVELOP.
