...A SNOW SQUALL WILL AFFECT SOUTHWESTERN DELAWARE AND NORTHWESTERN
SULLIVAN COUNTIES...

At 702 PM EST, a snow squall was located along a line extending from
near Harvard to near Downsville to near Willowemoc. Movement was
southeast at 35 mph.

Winds in excess of 30 mph are possible with this squall.

Locations impacted include...
Rockland, Walton, Colchester, Deposit, Hamden, Masonville, Hazel,
Harvard, Peabrook and Fishs Eddy.

A burst of heavy snow and winds in excess of 30 mph will cause 
visibilities to drop quickly to less than a quarter of a mile in 
this squall.

Use extra caution if you must travel into or through this dangerous 
snow squall. Rapid changes in visibility and potentially slick roads 
as snow melts and then quickly refreezes will lead to accidents.
