TT can expect more showers from Tuesday to Friday.
A five-day weather forecast for the period June 11-15 issued by Met Service via its Facebook page said low level convergence, equatorial moisture advection (the usually horizontal movement of a mass of fluid such as air or an ocean current) and build-up, and a low level perturbation (changes in the atmosphere) on Thursday evening to Friday morning, were expected to influence the weather across the country from Wednesday and for the remainder of the week.The rainy season was officially declared on May 25. Rains this past weekend resulted in flash flooding in parts of north Trinidad.
The release said the current analysis of a modulated Inter-Tropical Convergence Zone (ITCZ) due to the recent passage of a tropical wave and then another tropical wave expected to pass until Tuesday evening showed that there might be partly cloudy to cloudy periods with some light or moderate showers over varying areas, from early Tuesday morning.
There was also a medium chance for isolated heavy showers or a thunderstorm in a few areas, it added.
The release said, 'By Wednesday a weak ridge begins to form, and while this will influence generally fair weather across the Windward Islands, it is also expected to cause an increase in low level convergence just to the east-southeast and southeast of Trinidad.'
It added that the nearest tropical wave was expected to reach TT and the Windward Islands (Dominica, Grenada, Carriacou and Petite Martinique, Martinique (France), Saint Lucia, Saint Vincent and the Grenadines) by tomorrow.
From Thursday, there was likely to be some partly cloudy to cloudy periods with a few light to moderate showers and a medium chance of the development of an isolated heavy shower or thunderstorm in some areas due to a weak system.
Another tropical wave - a week away from the Lesser Antilles - was also being monitored by the service.
It added that a mild concentration of Sahara dust was expected but could increase to moderate between Tuesday and Thursday.
