THE NATIONAL WEATHER SERVICE IN FAIRBANKS HAS EXTENDED THE

* FLOOD ADVISORY FOR...

* UNTIL 415 PM AKDT MONDAY

* SEVERAL INCHES OF RAIN OVER THE PAST FEW DAYS HAS CAUSED THE
  TANANA RIVER TO RISE TO BANKFULL STAGE. AS A RESULT THE GROUND
  WATER TABLE HAS RISEN...CAUSING PONDING OF WATER IN LOW LYING
  AREAS. THIS HAS PARTICULARLY IMPACTED THE AREA DOWNSTREAM OF THE
  CONFLUENCE OF THE CHENA AND TANANA RIVERS.

* WATER LEVELS ON THE TANANA ARE EXPECTED TO RISE THROUGH MONDAY AND
  REMAIN HIGH INTO NEXT WEEK.

* THE RISING GROUNDWATER MAY MAKE SOME ROADS AND DRIVEWAYS IN THE
  ROSIE CREEK SUBDIVISION IMPASSABLE.  SOME AREAS IMPACTED INCLUDE:
  ROSIE CREEK...MELANIE LANE...BAURICK COURT...PERKINS DRIVE AND
  FRUSTRATION TRAIL.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

SAFELY.
