Saharan air in convergence zone preventing cyclone development
Friday 26th June 2020
Disturbance Fifteen is now passing around 100 miles north of the Netherlands Antilles, westbound at a brisk, cyclone-preventing 25 knots. This has picked up some moisture and is spreading rain across the coast of Venezuela, but has no development prospects.
Newbie Disturbance Sixteen has piped up three days west of the Cape Verde Islands and is moving slightly north of west at 12 knots. This looks to be making an early curve to the north-west which will take it clear of land should it survive the crossing. In any event, sand-laden Saharan air to the north and upper level shear to the west should prevent development.
