New departure from African coast may break deadlock
Monday 29th July 2019
Disturbance Twenty is located around 250 miles south-east of Puerto Rico moving to the west-nor'west at 12 knots. This formation is producing scattered thunderstorm activity across the Eastern Caribbean with signs of surface rotation on satellite imagery, prematurely exciting the Canadian guy. This is not expected to develop as it moves to the west-nor'west across the Caribbean today and across Hispaniola and eastern Cuba on Tuesday and Wednesday then across the Bahamas on Thursday and into Friday. Thereafter, development of a tropical depression or weak tropical storm to the north of the northern Bahamas is a possibility, but with a track clear of the eastern seaboard.
Disturbance Nineteen is now 800 miles north east of the mouth of the Amazon moving west at around 20 knots. Thunderstorm activity has diminished and rotation has decreased as it has moved into an unfavourable environment. No development is expected.
Disturbance Twenty One is now passing the Cape Verde Islands moving west-nor'west at 12 knots. This is producing numerous showers and thunderstorms and is showing some mid-level rotation but conditions will become less favourable as the week goes by. If this makes it to the Caribbean, a development window may be possible. Early days yet.
