...SIGNIFICANT RAINFALL THROUGH MONDAY NIGHT WILL BRING RIVER RISES
AND LOCALIZED FLOOD POTENTIAL TO THE WESTERN SUSITNA VALLEY...

 * Yentna and Skwentna River basins

 * Saturday Night through Monday Night

Rainfall:

* Widespread rainfall of 1.5 to 2.5 inches of rain is expected in

* Many lower locations along rivers such as gravel bars and other
  spots popular for camping and recreating may become inundated with
  water with rivers reaching bankfull conditions.

  locations with poor drainage.

Next Steps:

  should anticipate higher than normal water levels and are advised
  to monitor weather and river forecasts.

* Send weather or flooding reports to inws.ncep.noaa.gov/report/ or

  center by calling 1-907-266-5160.
