Weather Discussion

As the tropical wave near 63W continued westwards instability trailing over Barbados and the central section of the region generated cloudy skies and light to moderate scattered showers. Favourable upper-level conditions also allowed for isolated thunderstorm activity across the area. The 12-hour rainfall accumulations from 6pm til 6am here in Barbados ranged from 11.8mm here at Charnocks in Christ Church to a maximum of just over an inch (26.8mm) near Hope land, St. Philip. Other rainfall totals such as 22.6mm, 20.8 and 18.2 were also recorded in Mile and a Quater, St. Peter, Groves, St. Philip and Alleynedale Hall, St. Peter respectively. After midnight Barbados reported a gradual improvement while the islands of the Leewards and northern Windwards remained under similar weather conditions.

Eastern Caribbean Outlook:

Instability generated by moisture and instability trailing the wave at 63W will maintain light to moderate convection across the Leewards and northern Windwards where upper-level conditions will remain conducive for convective enhancement. During the night a shear line is expected to shift southwestwards while a low-level trough approaches the southern Leewards and northern Windwards. Elsewhere, a weak ridge pattern will be the dominant feature with occasionally cloudy skies anticipated.
