Oh say can you see, by the dawn's early light...

...satellite imagery overnight shows that Disturbance Thirteen has become better organised albeit still stationary as it was yesterday, at twilight's last gleaming. Centred around 700 miles east-nor'east of the Amazon delta, conditions gave proof through the night that this system may deepen into a tropical storm. This has started producing enhanced rainfall and thunderstorms. This should start to head a west-nor'west soon which will take this clear of the northernmost Leeward Islands but until this gets under way, any discussion on track is fairly speculative. This track reduces the chances of this entering the Caribbean and we can't rule out a track towards the eastern seaboard of the land of the free and the home of the brave. With huge apologies to Francis Scott Key and any baffled non-US readers.
