A system of low pressure could develop near Florida or off the southeastern coast of the U.S. over the Fourth of July weekend, or early next week.

Florida is in for a wet weekend as the chances that a tropical system will develop continue to climb. The National Hurricane Center raised the likelihood of development for a potential system near the northeast coast of Florida to 60% in the next seven days - up from 40% the day before - and for the first time gave the system a 20% chance of strengthening in the next day or two.
