...WINTER STORM WARNING IN EFFECT FROM 4 AM FRIDAY TO 4 AM EST
SATURDAY...

* WHAT...Heavy wet snow expected. Total snow accumulations of 5 to
  10 inches at higher elevations above 1000 feet and 2 to 4 
  inches in the valleys are expected.

* WHERE...In New Jersey, Sussex county. In Pennsylvania, Carbon 
  and Monroe counties.

* WHEN...Rain will transition to snow initially along the high-
  elevation ridges in the southern Poconos and far northwestern
  New Jersey between 4 and 8 AM Friday morning and then closer to
  midday in the valleys. The snow will be heavy at times during
  the day on Friday with snowfall rates of 1 to 2 inches per hour
  possible. The snow is expected to decrease in intensity later in 
  the evening before eventually ending from west to east 
  overnight.

* ADDITIONAL DETAILS...Plan on very difficult travel conditions,
  including during both the morning and evening commutes on
  Friday. The combination of strong northwest winds gusting to 50
  mph and heavy snow could create near-blizzard conditions with 
  visibilities below one-half mile at times. The heavy, wet nature
  of the snow and strong winds will likely cause damage to trees 
  and power lines that will lead to power outages.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Winter Storm Warning for snow means severe winter weather
conditions will make travel very hazardous or impossible. If you
must travel, keep an extra flashlight, food and water in your
vehicle in case of an emergency. The latest road conditions for

  from west to east late this evening and overnight though it may
  linger until early Saturday morning along the New Jersey coast.

* ADDITIONAL DETAILS...Although the snow has initially struggled
  to accumulate on paved surfaces due to a warm ground,
  temperatures have lowered to near freezing, allowing snow to
  accumulate on untreated secondary roads, bridges and overpasses
  especially after sunset and during bursts of heavier snow. Plan
  on slippery travel conditions, including for the evening
  commute. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Winter Weather Advisory for wet snow means periods of wet snow
will cause primarily travel difficulties. Be prepared for snow
covered roads and limited visibilities, and use caution while
driving. The latest road conditions for the state you are calling
from can be obtained by calling 5 1 1.
