ID=11950925(WBIR) A tropical storm off the coast of Florida could affect holiday travel plans for millions heading to the beach.

The National Hurricane Center expects Tropical Storm Arthur to hit the Carolinas Thursday night, and become a hurricane by July 4. It is expected to near the Outer Banks area around 2 a.m. Friday.

Officials said they would close Cape Lookout National Seashore at 5 p.m. Wednesday and reopen when it is safe.

Jill Sipos of Knoxville is getting married on the beach in Kill Devil Hills July 4, the day the storm is expected to hit the area.

10News spoke to her on the phone Tuesday night from the Outer Banks. Sipos said she vacations there the same time every year with her fiancé, Toby Keiser.

"We've never had a hurricane or... the possibility of a hurricane, I should say, until this year. It's just surprising," Sipos said.

According to Sipos, it will be a small wedding with only a few family members; they are waiting to find a backup location.

"Right now, I mean the weather is absolutely gorgeous. Gorgeous. It's crazy to think that a hurricane could be coming in three days," she said.

10News also reached out to viewers on WBIR's Facebook page.

Mary Cline of Knoxville changed her vacation plans saying, "We are putting it on hold until next weekend. Because of the storm. My family called and told me about the hurricane."

Christina Webster of Maryville wrote, "We are heading to Myrtle Beach for the weekend. We are leaving around 1 a.m. Friday morning. Hoping it will miss us!"

In an email, Chris Brown of Sevierville told 10News, "We have a house rented in Kill Devil Hills for the week and sure hope Arthur stays away."

The system is forecast to make its way up the East Coast, bringing heavy showers to New York City and Boston.

Arthur is the first named tropical storm of this year's Atlantic hurricane season.
