Sand continuing to suppress storm development
Saturday 11th August 2018
Disturbance Twenty Two is passing to the south of Puerto Rico, westbound at 12 knots. This has picked up a significant quantity of water en route and is producing a wide spread of squalls, mainly to the north and east of the nominal centre. Conditions aloft are still hostile towards vertical circulation which will prevent storm development.
Disturbance Twenty Four is centred around three days west of the Cape Verde islands westbound at 16 knots. Sand has killed of this system's early enthusiasm but it is still gathering moisture which will probably mean enhanced rainfall for the Lesser Antilles during next week, but little chance of tropical development.
