At least 30 people have died after a record-breaking snowstorm pummeled the Eastern Seaboard over the weekend. In Washington, D.C., federal offices remain closed today. The House of Representatives has postponed all votes this week. At least 12,000 flights have been canceled. Snowstorm Jonas was the single biggest snowstorm on record for at least six locations across the East Coast, including Baltimore, Maryland and Harrisburg, Pennsylvania. The highest total snowfall recorded was 42 inches—or three-and-a-half feet—in Glengary, West Virginia. The Weather Channel’s lead meteorologist Michael Palmer said, “It’s likely to go down as one of the most impressive blizzards we’ve seen on the Eastern Seaboard in recorded history.”
