HYDROLOGIC STATEMENT
NATIONAL WEATHER SERVICE FAIRBANKS AK
440 AM AKDT FRI JUL 27 2012
...HEAVY RAIN AT TIMES OVER NORTHWEST ALASKA THROUGH THE WEEKEND...
A SERIES OF LOW PRESSURE SYSTEMS AND WEATHER FRONTS WILL COMBINE
WITH A MOIST SOUTHWEST FLOW ALOFT OVER THE EASTERN BERING SEA TO
BRING PERIODS OF HEAVY RAIN TO NORTHWEST ALASKA THROUGH THE
WEEKEND.
SINCE TUESDAY MORNING 2.47 INCHES OF RAIN HAS BEEN OBSERVED AT
NOME WITH WIDESPREAD RAINFALL AMOUNTS OF ONE HALF TO ONE AND ONE
HALF INCHES ACROSS NORTHWEST ALASKA. ADDITIONAL RAINFALL OF 1 TO 2
INCHES OF RAIN IS EXPECTED OVER A BROAD AREA FROM THE SEWARD
PENINSULA NORTH TO THE BROOKS RANGE THROUGH THE WEEKEND. THE
HEAVIEST RAIN WILL FALL ALONG SOUTH FACING SLOPES...AND SOME
ISOLATED LOCATIONS COULD RECEIVE 2 TO 4 INCHES OF RAIN THROUGH
SUNDAY EVENING.
THERE HAS BEEN A BREAK IN THE RAIN DURING THE PAST 12 TO 18 HOURS
AS THE MOST RECENT WEATHER FRONT TO AFFECT THE AREA HAS PUSHED
WELL INLAND AND WEAKENED. ANOTHER LOW MOVING ACROSS FAR EASTERN
RUSSIA TODAY WILL SEND ANOTHER WEATHER FRONT INTO THE REGION
TODAY. A MOIST SOUTHWEST FLOW WILL TRANSPORT SIGNIFICANT MOISTURE
ACROSS NORTHWEST ALASKA.  RAIN...HEAVY AT TIMES IS EXPECTED TO
DEVELOP TODAY. THE HEAVIEST RAINFALL TODAY WILL LIKELY OCCUR
ALONG THE SOUTHERN SEWARD PENINSULA. YET ANOTHER WAVE OF LOW
PRESSURE IS EXPECTED TO DEVELOP IN THE EASTERN BERING SEA
SATURDAY...WITH THE POTENTIAL OF ADDITIONAL HEAVY RAIN AT TIMES
THROUGH THE WEEKEND.
THE HEAVY RAINFALL WILL CAUSE SMALL STREAMS AND CREEKS ON THE
SEWARD PENINSULA AND THE SOUTH FACING SLOPES OF THE WESTERN BROOKS
RANGE TO RISE RAPIDLY TO BANKFULL...AND POSSIBLY OVER BANK. THE
LARGER RIVERS IN THE REGION WILL ALSO EXPERIENCE SIGNIFICANT RISES
AND MAY APPROACH BANKFULL LEVELS AS THE WATER MOVES DOWNRIVER.
THE SNAKE RIVER NEAR NOME HAS RISEN ABOUT 3 FEET SINCE THE RAIN
BEGAN TUESDAY MORNING...BUT IS STILL WELL BELOW FLOOD STAGE.
PEOPLE LIVING...WORKING...OR RECREATING IN NORTHWEST ALASKA SHOULD
BE ALERT FOR RAPIDLY RISING WATER LEVELS AND MOVE THINGS TO HIGHER
GROUND. FURTHER STATEMENTS WILL BE ISSUED IF THE LIKELIHOOD OF
FLOODING IS IMMINENT.
