The National Weather Service on Wednesday issued its first watches for a winter storm that could wreak havoc on the northeastern United States this weekend.
The blizzard watch includes the cities of Baltimore and Washington and surrounding areas in Maryland and Virginia. It will formally go into effect on Friday afternoon and remain valid through Saturday night, the service said.
The National Weather Service said it’s “monitoring the possibility” that a storm could drop 1 to 2 feet of snow along the I-95 corridor this Friday and Saturday.
The stretch includes other major cities like Philadelphia, Boston and New York, though no watches for those areas had been issued as of mid-day Wednesday.
The service’s Weather Prediction Center warned of a “potentially paralyzing winter storm for portions of the Mid-Atlantic,” including possible blizzard conditions in Baltimore and Washington, and said more than a half-inch of ice was possible in Kentucky and North Carolina. Coastal flooding was also possible.
The blizzard watch cautions that the area could receive more than a foot of snow, with a wintry mix possible on Friday night. The storm is also expected to bring 40 mph wind gusts, which could lead to whiteouts and power outages.
“Heavy snow and blowing snow will cause dangerous conditions and will be a threat to life and property,” the watch states. “Travel is expected to be severely limited if not impossible during the height of the storm Friday night and Saturday.”
The blizzard watch encourages people to stock up on necessary items.
The service also issued less-severe winter storm watches for portions of Pennsylvania, West Virginia and Virginia, though still warned that a foot of snow was possible in some areas and said blowing snow could pose travel hazards.
The Weather Channel is calling the potential storm Winter Storm Jonas.
The threat came as another winter storm was moving across the country.
National Weather Service radar showed precipitation falling throughout the south, and winter weather advisories or winter storm warnings were in effect for portions of Ohio, Kentucky, Tennessee, Virginia, Georgia and the Carolinas.
On Tuesday, Georgia Governor Nathan Deal declared a state of emergency for 15 counties affected by winter weather.
