Thunderstorms and rain across Lesser Antilles
1030 GMT Monday 5th August 2019
Disturbance Twenty One is crossing the Lesser Antilles now, moving west at 13 knots. This has some thunderstorm activity and limited rotation associated with it and will bring some heavy rainfall to the islands over the next 24-36 hours. Thereafter, the system is expected to dissipate in the central Caribbean by the middle of the week.
Disturbance Twenty Three has piped up around 750 miles north of the mouth of the Amazon heading more or less north-easterly which will probably clear the Caribbean altogether. This system currently has a little thunderstorm activity associated with it, but not much in the way of rotation. A track towards the west-nor'west is expected over the next few days and thereafter the system is likely to dissipate to the north of Puerto Rico by the middle part of this week.
Disturbance Twenty Two is now 350 miles north east of the mouth of the Amazon moving west-nor'west at 18 knots. This is not showing any desire to get organised and is not well-prepared to survive the ravages of upper level wind shear which awaits ahead.
