The National Weather Service has issued a winter weather advisory in effect until 10 p.m. Tuesday for Jefferson and Lewis counties.

The NWS says an area of freezing rain will impact the eastern Lake Ontario region Tuesday afternoon as temperatures across this region remain near or just below the freezing mark in many locations across Jefferson and Lewis counties.

Ice accumulations are expected at a tenth of an inch.

This will keep untreated roads, sidewalks and parking lots very slippery and treacherous.

Motorists should use caution and be alert for very slippery travel.

Roads that appear just wet may in fact be ice covered.

The NWS also issued a freezing rain advisory for northern portions of the Saint Lawrence Valley from 7 p.m. Tuesday to 7 a.m. Wednesday.

Accumulations will range from a trace to a tenth of an inch of ice.

Freezing rain will develop across the northern part of the county around early evening and continue through sunrise before surface temperatures warm above freezing, changing precipitation to plain rain.

A hazardous weather outlook is in effect for the rest of St. Lawrence County.

Spotty freezing rain and/or drizzle is possible Tuesday evening through midnight as a warm front moves over the region.
