The TT Meteorological Service has advised that saharan dust concentrations are expected to increase over the next few days.
In its 5-Day Weather Outlook, the TTMS says there is currently mild Saharan dust in the atmosphere.
However, from today (Saturday 04th May 2024) concentrations are expected to begin to increase to moderate, eventually becoming high by Monday.
Moderate to high concentrations are then expected to persist for the rest of the outlook period.
The TTMS also warns that bush or brush fires, landfill or forest fires, together with the Saharan dust, may lead to a further reduction in the air quality.
Sensitive persons are advised to take the necessary precautions.
Meanwhile, with regard to the weather, some rain is in the forecast for the weekend.
The following is part of the TTMS’ 5-Day Weather Outlook:
Tomorrow (Saturday 04th May) a weak perturbation together with low level convergence is likely to cause some fair conditions to be interrupted by partly cloudy periods with a light or moderate shower in a few areas. A 40% chance for a heavy shower mainly over south east Trinidad and hilly areas, and a 10% chance for a thunderstorm favouring southwest Trinidad.
On Sunday 05th, a shift in the wind direction, backing from southeast to east and east-northeast, is expected to keep some of the equatorial moisture to the south of Trinidad, but low level convergence, moisture advection, and some heating, is likely to produce partly cloudy periods in some areas with a few light or moderate showers and a 20% to 30% chance for a heavy shower. There is a 10% to 20% chance for thunderstorm activity over south and southwestern offshore areas of Trinidad.
Although the surface wind is expected to continue from the east-northeast and east on Monday 06th, a steady mid-level wind flow from the southeast is likely to produce a resurgence of the equatorial moisture over Trinidad and Tobago during the morning. There is a 40% chance for a few heavy showers over southern, southwestern and eastern offshore areas of Trinidad and on land over the southwestern peninsular, with a 10% chance for a thunderstorm to develop. During the late morning to afternoon there is the chance for a few light or moderate showers in some areas to interrupt fair conditions. A 20% to 30% chance exists for the development of a heavy shower over western Trinidad or hilly areas.
Tuesday is expected to be mainly fair and sunny with brief showers in a few areas.
Wednesday generally fair with some partly cloudy periods producing a few brief, light or moderate showers.
