UPDATE 11/20/2019 5 AM:

Tropical Storm Sebastien has sustained winds of 50mph Wednesday morning and continues to move NW at 8mph away from the Leeward Islands and Bermuda. This storm will safely move over the open Atlantic before dissapating by the weekend.

UPDATE 11/19/2019 12 PM:

NHC is now issuing advisories on Tropical Storm Sebastien which is now just northeast of Puerto Rico. The storm will likely dissipate in a few days due to increasing wind shear with an approaching trough of low pressure and will merge with a cold front moving in from the west. Therefore there will be NO threat to the Caribbean or Bermuda and should stay out in the Atlantic.

UPDATE 11/19/2019 9 AM:

The National Hurricane Center has increased the chance of development to high for an area of low pressure 250 miles northeast of the northern Leeward Islands that continues to show signs of organization. It now has an 80% chance of development over the next couple of days and should become a tropical or sub-tropical depression soon. If it becomes a tropical storm it would be named Sebastien. Fortunately this system is moving northwest and will turn to the north not impacting the United States and moving away from any land in the Atlantic.

UPDATE 11/19/2019 5 AM:

The National Hurricane Center has increased the chance of development to high for an area of low pressure 200 miles east-northeast of the northern Leeward Islands that continues to show signs of organization. Although the surface circulation of the disturbance appears to be gradually consolidating, recent satellite-derived wind data indicate that it does not yet have a well-defined center. A tropical or subtropical depression is likely to form while the system moves northwestward and then northward over the open Atlantic during the next day or two. The low is forecast to interact with a front by midweek and further development is unlikely after that time

UPDATE 11/18/2019 12 PM:

We are getting close to the end of the 2019 Atlantic Hurricane Season and it appears that it is going for one last gasp before wrapping up. Invest 90L is just east of the Lesser Antilles. We will be watching this area for possible development in the next couple of days while conditions remain somewhat favorable for further development. The good news is it will not a be a threat to any land areas as a front will pick the system up and carry it out into the Atlantic. It may get close to Bermuda, but even this scenario is looking less likely.
