Weather: A few moderate to heavy showers affected the southern islands today, especially in Trinidad, where there was localized flooding. This should continue into Thursday and the first part of Friday. The rest of the islands are mostly isolated showers, with few moderate, mainly Windwards. This continues Thursday to at least the first part of Friday so expect continued chances for localized flooding in Trinidad.

The islands should have fewer showers on Saturday to Sunday(might actually have some more in a few islands late Sun).

Models indicating an upper low will deepen east of the islands by Saturday and move W-SW over the islands by early to middle next week. An increase in rainfall is shown from Monday onwards. The large-scale pattern(+ve Kelvin Wave) supports enhanced rainfall next week as well so we can have some degree of confidence in a wet pattern.

Whatever cleaning of drains, bridges and general cleanup need to be done after recent floods/landslides should be finished before next week.

During the period after midnight to sunrise, some periods of heavy showers and rain affected the Windwards and parts of the Virgin Islands. This morning there was an area of heavy rain that moved through parts of north Saint Lucia and St. Vincent. Amounts were less than last night, between 10mm and 25mm, with a few spots higher.

Current radar shows some showers around the Windwards and Leewards. The upper trough will continue to cause occasional light to heavy showers, periods of rain and a chance of thunderstorms rest of Tuesday to Wednesday. Gusty winds can accompany showers. There maybe a reduction in chances for heavy showers late Tuesday.

Infrared satellite loop with lightning strikes (white dots) over St. Lucia 6:55pm to 11:45pm. The colors represent cloud top temperatures; the colder they are (usually near thunderclouds) the more likely there is also heavy rain… In this loop you see various thunderclouds form, merge and then finally the tops gets pushed southeast by the upper level winds. During the time it maintains itself the balance of the steering winds can cause the tall thunderclouds to move slower.
