Letís hear it for upper level wind shear

Tuesday 6th August 2019

Disturbance Twenty One passed the Leeward Islands overnight and is moving west at 18 knots. Despite continued surface circulation and some thunderstorm activity, southwesterly wind shear will prevent development.

Disturbance Twenty Three is around 300 miles east of Anguilla moving west-nor'west at 14 knots. This also has some disorganized thunderstorm activity and limited rotation associated with it but buffering south-westerly wind shear and expected to dissipate north of Puerto Rico by Thursday without tropical development.

Disturbance Twenty Two is centred 400 miles north of the mouth of the Amazon moving west at 18 knots. This is already weakening and unlikely to survive the ravages of upper level wind shear.

Stand easy.
