Five disturbances at large, but no development expected
General overview Saturday 15th August 2015
Disturbance twenty four ended a totally uninspiring crossing from west Africa to Central America, disappearing ashore into Nicaragua overnight. Finished with engines.
Disturbance twenty seven is now centred around 150 miles south west of the mouth of the Mississippi and westbound at 8 knots. This system will continue spreading enhanced showers and thunderstorms as it moves westward and by tomorrow will produce showers and thunderstorms across the north-western and west-central Gulf of Mexico, increasing rainfall across east Texas and southern Louisiana from Sunday through Monday. Despite many of the ducks being in a row, this is still unlikely to develop.
Disturbance twenty six is a day into the south eastern Caribbean and moving west-nor'west at 12 knots. This will enhance showers and storms over Puerto Rico and Hispaniola today and tomorrow but tropical development is not expected.
Disturbance twenty five has slipped even further north, now almost clear of the intertropical convergence zone altogether but still aimlessly drifting in a generally westerly direction at about 12 knots. This is weakening and likely to only have a day or two left in it.
Disturbance twenty eight has slipped the surly bonds of earth and galloped clear of the African coast, passing the Cape Verde Islands now, westbound at about 14 knots. Early days, but no more promising at the moment than any other disturbance we have seen since disturbance thirteen became CLAUDETTE over a month ago.
