Trump tweeted the comment at about 12:30 p.m., with the storm already hitting New York City.

Trump's business empire is based in New York City -- Trump Tower is located in Midtown Manhattan -- but the real estate mogul seemed more concerned that President Obama would miss the deadline Trump set last week on an offer to trade Obama's passport and college applications for $5 million to the charity of the president's choice.

Obama, who has canceled campaign events on Monday and Tuesday in order to oversee the emergency response to the storm, did respond to Trump last week on "The Tonight Show."

"We had constant run-ins on the soccer field," Obama joked. "He wasn't very good and resented it. When we finally moved to America, I thought it would be over."

Trump's offer expires at 5 p.m. on Tuesday.
