A tropical wave 450 miles southwest of the Cabo Verde Islands has been identified as having a "medium chance" of becoming a tropical cyclone in the next five days. If it were to strengthen into a tropical storm, it would be the fourth named storm of the season and called Don.
Long range forecast data suggests the system will move west-northwest at around 10 mph through the week and potentially be located a few hundred miles northeast of the Leeward Islands by Friday. There are no tropical weather threats to the United States or Florida in the next five days.
