Two active systems westbound

Friday 29th July 2016

Disturbance eighteen is now 1180 miles east of the islands of the eastern Caribbean and still galloping west at over 20 knots. At this course and speed, the disturbance is likely to enter the Caribbean by late Sunday. Squalls have increased albeit still poorly organised. In a week from now the disturbance may enter the south-western Gulf of Mexico. There is less chatter about significant development now but it's still early days.

Disturbance twenty is about 250 miles south-sou'west of the Cape Verde Islands, moving west at 12 knots. The disturbance has become well organised overnight and squalls have increased. Only a slight improvement in organisation would result in the formation of a tropical depression. However, environmental conditions are likely to become less favourable after today and no further development is expected until or unless this survives the Atlantic crossing.

Stand easy.
