Special Tropical Weather Outlook to add discussion of a new system over the central Atlantic.
The National Hurricane Center is issuing advisories on Post-Tropical Cyclone Jose, located a little over a hundred miles south-southeast of Nantucket, Massachusetts, and on Hurricane Maria, located just to the north of Grand Turk Island.
Updated: A small area of low pressure has developed over the central Atlantic Ocean almost a thousand miles east-southeast of Bermuda. The low is producing a concentrated area of showers and thunderstorms, although the circulation appears somewhat elongated. Some additional development of this system is possible during the
next few days while it moves slowly northward through early next week.
