Subtropical Storm Sean Developing?

A disturbance between the United States and Bermuda continues to produce very strong winds as it moves slowly westward. The system will eventually turn more northwesterly and then northerly, but will have enough time in a somewhat favorable environment to develop into a subtropical storm. If it does so, it would be called Sean, and the spaghetti plot above shows the collective model tracks over the next 5 days (120 hours). There will not be a threat of wind or rain to the Mid-Atlantic Coast, but rough surf and associated beach erosion will continue until this system moves north later in the week. Hurricane season officially runs until the end of November, so it's not that unusual to still have activity in the Atlantic Basin. -ZD
