Showers and thunderstorms have increased and grown more organized in association with an area of low pressure that has formed between the Bahamas and Bermuda (Invest 91L). This low appears increasingly likely to develop into a tropical or subtropical depression as it moves west-northwest or northwest towards the Southeast U.S. coast over the next few days. Should it become a named storm, it would be called Bonnie...

Sea surface temperatures (SSTs) near 91L's center were about 26 - 27°C (79 - 81°F), which is 1 - 2°C (1.8 - 3.6°F) above average. These waters are only marginally warm enough to support formation of a tropical storm, and 91L is likely to take on the characteristics of subtropical system instead of a tropical system
