While he's sticking to his previously-scheduled events, GOP presidential candidate Mitt Romney is also continuing to monitor the storm and has been in touch with New Jersey Gov. Chris Christie (R) and Virginia Gov. Bob McDonnell (R), according to campaign spokeswoman Andrea Saul.

Romney TV ads are still airing, but the campaign is suspending fundraising e-mails to the District of Columbia, Virginia, Pennsylvania, North Carolina, New Jersey, Maryland and New York. The Obama campaign is similarly suspending fundraising e-mails in states affected by the storm.

In North Carolina, New Hampshire, Pennsylvania and Virginia, the Romney camp will be collecting supplies at campaign offices to deliver local storm relief, and in Virginia, staffers will be collecting storm relief supplies on the Romney campaign bus, Saul said.

On Romney's Twitter and Facebook feeds and Web site, the campaign has posted an appeal to supporters to make donations to the Red Cross, and Romney on Monday issued a message to those in the path of the storm.

Professional emergency managers have long agreed that monetary donations, not supplies, are most effective in the hours after a major disaster.

"For safety's sake, as you and your family prepare for the storm, please be sure to bring any yard signs inside. In high winds they can be dangerous, and cause damage to homes and property," the message reads. "I'm never prouder of America than when I see how we pull together in a crisis. There's nothing that we can't handle when we stand together."
