Invest 91L has been upgraded to TD7 in the far eastern Atlantic. This system is forecasted to become Tropical Storm Grace later today. TD7 will track towards the west and gradually intensify into a 60-70 mph tropical storm before weakening as it reaches the Caribbean Islands in about a week. We will have a much more detailed post on this new system later today. Receive our detailed discussions via email as soon as they are published, please tap here.
