Airlines canceled thousands of flights, disrupting the plans of travelers all over the world, and storm damage was projected at $10 billion to $20 billion, meaning it could be one of the costliest natural disasters in U.S. history.
As the storm raged, disaster relief agencies scrambled to send workers and supplies to affected areas. Ken Garcia, spokesperson for the American Red Cross' Central and Western Oklahoma Region, said Oklahoma sent two volunteers to New Jersey and a third to New York to provide relief.
The organization had planned to send more volunteers, Garcia said, but airports in the area are closed, meaning volunteers couldn't reach the area.
The Salvation Army's Arkansas and Oklahoma Division is collecting monetary donations for disaster relief, said Cindy Fuller, a spokeswoman for the division.
Staffers from across the East and South are already working in affected areas all along the eastern seaboard, she said.
In Manhattan's Chelsea district, Lane Savage, an Oklahoman who moved to New York five years ago, said the wind was blowing at about 30 mph Monday afternoon, with heavy gusts.
Savage, a media production specialist at Comedy Central, said he'd been to several stores looking for basic supplies like flashlights and batteries.
On Monday morning, he went to a grocery store to pick up a few more things before the storm hit.
The storm disrupted an Oklahoma State University student group's travel plans. A team from OSU took third place at the American Institute of Chemical Engineers' Chem-E-Car competition, an alternative fuel technology contest in Pittsburgh.
But once the competition ended, students found out their flights were canceled. After a series of phone calls, the team arranged to take a bus to Cleveland. They will fly to Oklahoma City on Tuesday.
Flying out of Boston's Logan International Airport, Dr. Robert Bogardus, a radiation oncology professor at the University of Oklahoma Health Sciences Center, had a unique view of the storm.
About 5 a.m. Monday, Bogardus was watching from a window seat on an American Airlines flight as a full moon lit up swirling clouds above Boston.
Bogardus arrived in Boston on Saturday to attend the American Society for Radiation Oncology annual meeting.
However, after watching horizontal rain from his hotel window, he decided it was best to head home early.
