The EMA’s Air Quality Index has registered Red or “Unhealthy” in Port of Spain and Toco, and Orange or “Sensitive Groups” in Scarborough, Point Lisas, Mayaro, San Fernando and Arima.
The readings at 11am come as communities across the country continue to grapple with an increase in Saharan Dust concentrations.
The Met Service says a moderate to high concentration of Saharan dust is present and is urging persons to exercise the necessary precautions.
It also warns that significant concentrations of Saharan dust are expected to persist throughout the week.
According to the TTMS, the proportion of dust haze days is highest in June, followed by May and July.
This period is also deemed the peak of the local Saharan Dust Haze Season.
