748 AM AKDT Thu Apr 18 2024

...BLIZZARD WARNING IN EFFECT UNTIL 4 PM AKDT THIS AFTERNOON...

* WHAT...Blizzard conditions expected. Total snow accumulations 
  of up to two inches.

* WHERE...Kuskokwim Coast, Toksook Bay area.

* WHEN...Until 4 PM AKDT this afternoon.

* IMPACTS...Travel could be very difficult.

* ADDITIONAL DETAILS...Snow and strong winds gusting 40 to 50 mph
  from the northwest overnight has led to reduced visibility of
  one half mile or less for several hours overnight. Latest
  observations have reduced visibility further to one quarter mile
  with heavy snow and sustained northwest winds of 35 to 40 mph
  with gusts up to 50 mph. The worst conditions are expected to
  continue through this morning and into the early afternoon
  before snow and winds ease a bit. Farther inland from the coast,
  rain is observed in Bethel and remains out of the threat.
  Farther west toward Nunivak Island, light snow showers at times
  with no reductions in visibility expected during the day today.
  Heavier snow is expected to return late tonight with the 
  strongest winds shifting toward Nunivak Island.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Blizzard Warning means severe winter weather conditions are
expected or occurring. Falling and blowing snow with strong winds
and poor visibilities are likely. This will lead to whiteout
conditions, making travel very hazardous. If you must travel,
have a winter survival kit with you. If you get stranded, stay
with your vehicle.
