...AN AREA OF HEAVY SNOW SHOWERS WILL AFFECT EAST CENTRAL JEFFERSON 
AND NORTHEASTERN LEWIS COUNTIES...

At 749 PM EST, an area of heavy snow showers was located along a 
line extending from near Fort Drum to near Harrisville. Movement was 
east at 45 mph.

Winds in excess of 40 mph are possible with this area of heavy snow 
showers, which will combine with brief heavy snow to reduce 
visibility to a quarter mile for a short period of time. 
Accumulations will be minor, but travel conditions will rapidly 
deteriorate. 

Conditions can deteriorate rapidly in winter weather situations. Be 
prepared for very poor visibility and snow covered roads. Slow down 
and allow extra time when traveling.
