Two enthusiastic but unimpressive westbound runners

Saturday 20th June 2020

Disturbance Nine dashed across the Windward Islands overnight on its 25 knot westerly track. Upper level wind shear and a sprightly ground speed are keeping this disorganised and it is unlikely to develop. Nonetheless, this has a wide radius of heavy showers and thunderstorms which will be felt across the Lesser Antilles and towards the Netherlands Antilles over the next 24 hours.

Disturbance Twelve is now around 1450 miles west of the Windward Islands, also making good 25 knots as it heads due west. This still has some Saharan air in its outer reaches and upper level shear ahead which will keep development in check.

Stand easy.
