Winter storm Jonas has swept northwards along eastern USA, affecting over 80 million people.

The Nor’easter brought high levels of snowfall and winds up to 80 mph (130 kmh). At least 18 deaths, mostly from road accidents, have been blamed on the weather since Friday 22 January 2016.

According to NOAA figures of 24 January, 28.1 inches of snow was recorded at Newark Airport between 21 January to 24 January. JFK Airport saw 30.5 inches, La Guardia 27.9 inches and Central Park, NYC saw 26.8 inches.

States of emergency were declared in New York, Tennessee, Georgia, Kentucky, North Carolina, New Jersey, Virginia, West Virginia, Maryland, Pennsylvania and the District of Columbia.

Coastal Flooding in New Jersey and Delaware

Although snow and strong winds have been the cause of most of the problems, the storm also brought some flooding to areas of New Jersey and Delaware. Very high tides had been predicted for the weekend, but water levels were increased by up to 3.5 feet (1 metre) or more by the strong winds of storm Jonas.

On 23 January, a NOAA statement said:

“Water levels are increasing or elevated from North Carolina to Massachusetts. Water levels from North Carolina to New York range from 2.0 to 3.5 feet above tidal predictions. Stations across southern New England generally are showing values of 1.5 to 2.0 feet above normal tide levels, with water levels over 2.6 feet above tidal predictions at Nantucket Island, MA. Winds are increasing from Connecticut northward and generally decreasing from New York southward. Barometric pressure is falling along the mid-Atlantic coast from Montauk, NY northward and rising at stations southward”.
