Parts of four key states are in the storm's path: Virginia, North Carolina, Ohio and New Hampshire.
Mr Obama scrapped plans to hold three events in three states with former president Bill Clinton.
Instead he was to attend only a morning rally in Florida, then head back to Washington to oversee the government's emergency response.
Mr Romney cancelled a trio of Virginia events, but was scheduled to visit Ohio, Iowa and Wisconsin. However his aides predicted more scheduling changes were on the way.
