Atlantic production line in full flow

0930 GMT Saturday 27th July 2019

Disturbance Twenty has piped up just short of a day's steaming east of Trinidad, westbound at 12 knots. This has some surface circulation and will enhance shower and thunderstorm activity, with squalls in places, across the Lesser Antilles tomorrow. Environmental conditions are not favourable for tropical development as the system tracks west into the southern Caribbean.

Disturbance Eighteen is centred around 650 miles north-nor'east of the mouth of the Amazon and is moving west at around 14 knots. Thunderstorm activity has decreased as the system has moved into an area of drier air. No development is expected.

Disturbance Nineteen is now around a day's steaming west of the Cape Verde Islands, westbound at 14 knots. This system has some rotation and lusty thunderstorm activity associated with it but will be moving into a less favourable environment over the next few days. No development is expected.

A new development is gathering a head of steam over west Africa and is set to join the convergence zone production line over the next 24 - 48 hours. It is only a matter of time before one of these breaks the grip of dry, Saharan air over the region and forms vertical convection.

Until then, stand easy.
