Icy Waters off the U.S. East Coast
acquired January 7, 2018

After a powerful nor’easter dumped snow across a thousand miles of the U.S. East Coast, yet another blast of bitterly cold air spilled into the region and drove already low temperatures even lower.

Statisticians and meteorologists had plenty to tally as city after city broke daily low temperature records, but perhaps the most dramatic sign of the extreme cold emerged offshore. Many rivers, bays, and estuaries along the coast froze over, including some that only rarely have ice.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on Terra captured this trio of images on January 7, 2018. The first shows ice in Delaware Bay—between New Jersey, Pennsylvania, and Delaware—and the northern part of the Chesapeake Bay in Maryland. The second shows ice in the Albemarle Sound in North Carolina. The third shows Rhode Island and southeastern Massachusetts, with ice in Buzzards Bay and Nantucket Sound.

The U.S. Coast Guard warned mariners of icy conditions and started operations to break up ice in some areas. Basins and waterways that are shallow and less salty, such as coastal rivers and estuaries, tend to freeze before deeper, saltier water. (While fresh water freezes at 32°F (0°C), seawater freezes at 28 °F.)

On January 7, 2018, several cities experienced record low temperatures, according to the National Weather Service. Temperatures dropped to -20 degrees Fahrenheit (-29 Celsius) in Burlington, Vermont; -11°F in Portland, Maine; -2°F in Boston, Massachusetts; -9°F in Hartford, Connecticut; 2°F in Wilmington, Delaware; 1°F in Baltimore, Maryland; and 4°F in Raleigh, North Carolina.
