Overview
- Interior New York and New England logged widespread 5 to 10 inches of snow with localized foot‑plus totals on higher terrain and near Lakes Erie and Ontario, while many coastal corridors saw cold rain.
- Winter storm warnings and advisories remain in effect into early Wednesday as snowfall rates near or above 1 inch per hour produced hazardous commutes and hundreds of school closures.
- Travel snarled across the region, with about 3,184 U.S. flights delayed and Pennsylvania State Police reporting 289 crashes and 300 stranded motorists during the morning hours.
- New Jersey declared a state of emergency for Hunterdon, Morris, Passaic, Sussex and Warren counties as authorities urged limited travel and preparedness for rapidly changing conditions.
- The storm is forecast to intensify and race toward Atlantic Canada, with an Arctic air surge to follow and a second, quick‑hitting system later this week expected to bring lighter snow, generally 3 inches or less.
