Sahara sand enters tropical Atlantic
Thursday 11th August 2016
Disturbance twenty two remains is a broad area of low pressure centred over southern Mississippi. It continues to produce showers and thunderstorms from southeast Louisiana into the Florida Panhandle and across the north-central Gulf. This low will drift west-nor'west across southwest Mississippi and north Louisiana through Saturday. Since the system will remain inland, this has now no chance of developing. As this creeps away from having a marine impact it drifts off my radar and out of my heart. Suffice to say, it's raining.
Disturbance twenty three is located over the Lesser Antilles and moving to the west-nor'west at 15 knots. The disturbance will produce a few squalls across the Lesser Antilles but no short term development is expected however the ducks could be in a row when it moves into the Bay of Campeche by Tuesday of next week. At that time, it will increase shower and thunderstorm activity across the Gulf and Bay of Campeche before moving into Mexico. Whether it steps up to the plate and develops tropical characteristics remains to be seen.
Disturbance twenty four is now about 400 miles southeast of the Cape Verde Islands and is moving west at 7 knots. Saharan dust has spread across the intertropical convergence zone and is likely to continue for the next ten days, which is a sure cyclone killer.
