Two new disturbances across the tropical Atlantic
Wednesday 19th June 2019
A tropical wave - designated Disturbance Five - has developed some 300 miles east of the Windward Islands moving west at 15 knots. This will cause increased shower and thunderstorm activity across the Windward Islands, Leeward Islands, and northern Venezuela tonight but is not expected to develop further as it crosses the Caribbean due to strong upper-level winds shear ahead.
At the same time, Disturbance Six popped up 500 miles west of the Cape Verde Islands, westbound at 12 knots. Dry Saharan air awaits which should keep development in check. This might find more environmental sympathy as it approaches the Caribbean this coming weekend, but wind shear remains a safety factor for now.
