According to the Weather Channel, Irene is currently a powerful category three storm, and the service has added an "extreme" threat level category to describe the impending situation from eastern North Carolina to southern New England. Irene is expected to hit the Carolinas late Friday night, moving through the northeast this weekend into early Monday.

As of 8:00 p.m. eastern time Wednesday, a map showed Irene over the Caribbean islands with winds of 120 mph, moving northwest at 12 mph.

Major airlines are still operating as normal, but are already offering compensation to those whose travel plans have been affected. Right now, that applies to those with flights into or out of Caribbean airports.

American Airlines and US Airways will waive fees for one ticket change.

United travelers may make one change to their trip without penalty, and those with already canceled flights are entitled to a refund.

Continental is offering refunds to those whose Caribbean flights have been cancelled or delayed more than two hours. Penalty-free rescheduling is also being offered.
