US National Hurricane Center update: 11:05 (EDT) Tuesday 21st July 2020.

"Updated: Satellite imagery and recent satellite wind data indicate that the low pressure system located about midway between the west coast of Africa and the Lesser Antilles continues to get better organized. If current trends continue, advisories could be initiated on this system as a tropical depression later today.

Regardless of development during the next couple of days, less favorable conditions should limit additional development by the weekend."
