Jersey, northern Delaware, and the northern portions of the
Eastern Shore of Maryland.
* HAZARD TYPES...Heavy snow and strong winds.
* ACCUMULATIONS...Potential for storm total snowfall greater than

a sharp gradient will exist between the heaviest snowfall and
locations where very little snow may occur. Changes to the

the total accumulations.

across the watch area. Snow will continue on Tuesday with
potential for transition to a wintry mix or rain southeast of
I-95. Any wintry mix or rain may transition back to snow
Tuesday evening before diminishing Tuesday night.
* IMPACTS...Heavy snow may cause significant travel disruptions.
* WINDS...Northeast 10 to 20 mph with gusts up to 40 mph. The
highest winds should occur southeast of the I-295 corridor.
A Winter Storm Watch means there is a potential for significant
snow...sleet...or ice accumulations that may impact travel.
