Even as Hurricane Harvey brings catastrophic flooding to Texas, another tropical system is set to disrupt air travel along the U.S. east coast.
According to the latest forecast from Accuweather, Potential Tropical Cyclone 10 may evolve into Tropical Storm Irma through midweek, bringing locally dangerous surf, drenching showers and gusty coastal winds to an area including Myrtle Beach, South Carolina; Wilmington, North Carolina; Norfolk, Virginia; Ocean City, Maryland; Philadelphia; Atlantic City, New Jersey; New York City; and Martha's Vineyard, Massachusetts. Rain could spread from South Carolina to southeastern Virginia Tuesday and to Massachusetts on Tuesday night. Later in the week, the storm will most likely head out to sea over the North Atlantic.
Airlines have issued a number of travel waivers ahead of the storm.
American Airlines has issued a waiver for customers booked through affected airports through August 29. Customers can rebook for travel through September 1 between the same city pair in the same cabin (or pay the difference).
United Airlines has issued a waiver for travel through August 29 on new flights departing on or before September 1 between the same city pair in the originally ticketed cabin.
Delta has also issued a waiver for travel August 29. The new ticket must be reissued on or before September 1 with rebooked travel to begin no later than that date.
