Arthur Forms In The AtlanticThe first tropical storm of the 2014 Atlantic hurricane season has formed off the east coast of Florida, and will pester much of the U.S. East Coast between now and the July 4 holiday weekend. Named Arthur, it is the latest first tropical storm (in any given season) to form in the Atlantic since 2004.

Arthur is forecast to crawl up the Southeast coast over the next two days, slowly strengthening. The National Hurricane Center predicts Arthur will then reach category 1 hurricane early Friday, July 4, when it lifts north from the North Carolina Outer Banks to offshore the Delmarva Peninsula.

At present, the storm is stalled just 70 miles east of Vero Beach, Fla. and about 70 miles north of Freeport, Bahamas.  Thus far, its development has been slow. But conditions are favorable for slow strengthening and multiple aircraft flying into the storm today will monitor changes in intensity.
