Tropical Storm Sebastien has formed in the Atlantic with 45 mph winds. It is our first November named storm since 2017. It currently sits in the open waters of the Atlantic, and is not expected to impact any land areas during its life cycle. The storm could strengthen a bit over the next day or so. It is currently battling dry air to its west and some upper level wind shear. But thanks to a trough to its west, we may see some slight intensification. Within the next 48 hours, Sebastien should become absorbed into a cold front and accelerate north and then northeast in the Atlantic.

The area of low pressure in the Atlantic we have been watching is getting better organized. Shower and thunderstorm activity has been developing closer to the center. It sits 250 miles northeast of the northern Leeward islands. It could become a tropical or subtropical depression over the next day or so. Regardless of development, the system will remain over the open waters of the Atlantic. By mid to late week, it will get absorbed into a front which will help inhibit further development.
