NEW YORK (AP) — Businesses and homeowners across the northeastern U.S. are digging out after an overnight snowstorm that closed schools and slowed the morning commute.

Parts of New England were covered in more than a foot of fresh snow. The storm dropped as much as 11 inches (28 centimeters) in the New York metro region, with Central Park receiving about 5 inches (13 centimeters).

Pennsylvania’s department of transportation issued speed and commercial vehicle restrictions Sunday into early Monday morning. In New Jersey, Gov. Phil Murphy declared a state of emergency for all 21 counties.

The storm may have contributed to the death of two teens in a single-car accident about 30 miles (48 kilometers) north of Philadelphia Sunday evening. The driver, a 17-year-old, was hospitalized.
