Satellite imagery and weather data indicates that a strong non-tropical low pressure system is currently located offshore of the Mid-Atlantic coast near 36.7 North Latitude, 69.3 West Longitude at the time of this post. This storm system is designated Invest 93-L by the National Hurricane Center, but has yet to start transforming into a sub-tropical or tropical storm. That being said, careful analysis of the data indicates that this low pressure system may be starting to shed its fronts & thus may be starting its transformation into a sub-tropical storm.
It is expected that Invest 93-L will remain nearly stationary offshore of the Mid-Atlantic coast the rest of today right into Thursday. After this, it is expected that this low pressure system, which may be a sub-tropical storm by this point, will head northeastward and move out into the open North Atlantic and away from the East Coast of the United States.
Until then, persistent onshore winds will produce additional coastal flooding and beach erosion from southern New Jersey through the North Carolina Outer Banks the rest of today into Thursday. Additionally, winds are expected to gust up to 40 mph at times along the south coast of New England and across Long Island the rest of today into Thursday.
Elsewhere Across The Atlantic, Caribbean & Gulf: There are no other areas of concern across the rest of the Atlantic Basin & it appears that the chances for additional tropical development are extremely low through this weekend & probably through next week.
That said, it should be noted that model guidance are showing the possibility of another low pressure system forming near the Bahamas and then heading northeastward out into the open North Atlantic during the first half of next week. All-in-all though it appears that any low pressure system should stay non-tropical & not be a serious threat to any land areas. One thing that this low pressure system might do is produce widespread shower activity across the Bahamas and across eastern and southern parts of the Florida Peninsula during this weekend into the first half of next week.
