The revised schedule for the GOP convention runs from Tuesday to Thursday.
Romney campaign adviser Russ Schriefer said officials are monitoring the weather closely and left the door open to more schedule changes.
Schriefer said he didn't want to discuss "hypothetical" cancellations but “our concern has to be with the people in the path” of the storm.
Under the revised schedule, Mitt Romney will be nominated Tuesday night and give his acceptance speech Thursday night.
Former Arkansas Gov. Mike Huckabee, originally slated to speak Monday night, will speak Wednesday night under the new schedule.
Jeb Bush, the former Florida governor, will now deliver his remarks Thursday night before Romney’s speech.
The lineup of primetime speakers for 10 p.m. to 11 p.m. on Tuesday, Wednesday and Thursday, when the networks will provide coverage, is unchanged.
