Floridians faced sweeping changes on July 1 as new legislation making "dangerous excessive speeding" a criminal offense in the state went into effect.

Nearly 150 laws went into effect in Florida on July 1, including a wide variety of new crimes, harsher penalties, and changes to law enforcement.

A new Florida law targeting so-called "super speeders" is now in effect, imposing tougher penalties on drivers caught going 50 miles per hour or more over the speed limit or driving recklessly at 100 mph or faster.

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.
