Watch out America, tropical storm Arthur is coming your way and could spoil Friday's Fourth of July celebrations.

US weather forecasters expect the first named tropical storm of the season to turn into a Category 1 hurricane on Thursday, hitting the East Coast with winds speeds of 75 mph.

Earlier today, Arthur was located about 100 miles (160 kilometers) east-northeast of Cape Canaveral, Florida, and is expected to move north towards the Carolinas.

The hurricane watch in North Carolina covers the area from Bogue Inlet to Oregon Inlet, including Pamlico Sound. A tropical storm watch was also issued for parts of Florida and South Carolina, including Myrtle Beach.

With the July 4th weekend on the horizon, Arthur threatens to spoil America's most patriotic holiday and firework displays could be called-off along the east coast depending on the intensity of the storm.

The July 4th weekend celebrates America's Declaration of Independence from Great Britain in 1776 and sees huge firework displays, concerts and parades across the country.
