Snowfall accumulation

Snowfall accumulation

Spring officially started this week, but winter held one last punch for the Northeast, sending the fourth nor’easter in three weeks up the Interstate 95 corridor on Wednesday.

This winter was one for the record books.

Erie, Pa. — no stranger to snow — shattered records in late December when the city got more than four feet of snow in just 30 hours. Mount Baker in Washington received nearly 850 inches (more than 70 feet). Northern suburbs of Atlanta had about 10 inches (the average is three), an inch or so more than Washington, D.C.

March’s four nor’easters dumped more than 15 inches of snow on Philadelphia, missing the record for snowiest March by only 2 ½ inches. For the District, this week’s storm was the most so late in the year since 1964.

Although the D.C. region finished the winter strong, it only saw about eight inches of total accumulation all season, partly because of the “snowhole” effect. The area normally gets about 15.
