Winter Storm Warning
Statement as of 3:12 PM EST on February 9, 2010

... Winter Storm Warning now in effect from 7 PM this evening to
midnight EST Wednesday night...

The Winter Storm Warning is now in effect from 7 PM this evening
to midnight EST Wednesday night.

Low pressure forming over the South Carolina coastal waters will
become the main low pressure system tonight as it starts to
intensify rapidly. By Wednesday morning... this nor/Easter is
forecast to be just east of our area... and will bring heavy snow
to a good part of our area into Wednesday evening.

From the Interstate 95 corridor southeastward the snow may mix
with sleet at times late tonight... and with sleet and rain at
times during the first half of the day Wednesday. However... this
is more likely closer to the coast. As colder air wraps around
the storm even these areas are expected to change back to all
snow.

Total snow accumulations are expected to range from 10 to
20 inches with the highest amounts northwest of the Interstate 95
corridor. The heaviest accumulations as of now are expected to
occur in the Philadelphia northwestern suburbs. Heavy snow is
expected to occur in two bursts across the region. The first is
expected to occur tonight with three to eight inches likely to
accumulate by the morning commute Wednesday. The second shot will
be an even more intense burst of heavy snow with the upper air
disturbance itself that should occur in most of eastern
Pennsylvania... Maryland... and Delaware during Wednesday morning
and New Jersey and northeastern Pennsylvania during Wednesday
afternoon. The snow will end by midnight Wednesday night.

Winds will increase as Wednesday continues and will cause
considerable blowing and drifting of snow... even more than what
occurred with the weekend snow storm. At and near the Atlantic
shore blizzard conditions are possible Wednesday afternoon and
evening as winds increase.

Driving will be hazardous at best during this winter storm. It is
highly recommended that where possible to take mass transportation
Wednesday and only drive if its truly an emergency situation.

A Winter Storm Warning means significant amounts of snow and
sleet are expected or occurring. Strong winds are also possible.
This will make travel very hazardous or impossible.
