Jefferson-Lewis-
431 PM EST WED JAN 30 2019
...A BAND OF LAKE EFFECT SNOW WILL AFFECT JEFFERSON AND LEWIS
COUNTIES...
At 421 PM EST, A band of lake effect snow producing snow fall rates
of 2 to 3 inches per hour continues from Cape Vincent east to
Harrisville. This band is expected to drift further south during
the remainder of the afternoon. Meanwhile, a weaker band to the
south near Adams is drifting north and merging with the stronger
band over the Black River Valley. Both bands will continue to edge
closer to each other with a single intense band from Watertown east
later this evening. This will produce blizzard conditions with
frequent whiteouts. This will create a dangerous situation for
anyone on both primary and secondary roadways.
Meanwhile, temperatures are only a few degrees above zero and will
drop below zero this evening. This together with increasing winds,
will create windchills that will drop to -25 below zero this
evening. As a result, spending time outside may lead to a life
threatening situation without proper winter gear.
Locations impacted include...
Watertown, Sandy Island Beach State Park, Fort Drum,
Stony Point, Carthage, Lowville, West Carthage, Clayton, Adams,
Dexter, Glen Park, Herrings, Adams Center, Redwood, Henderson
Harbor, and Barnes Corners.
This includes Interstate 81 between exits 38 and 51.
Visibilities will drop quickly to less than a quarter of a mile in
this band of lake effect snow.
