The Trinidad and Tobago Meteorological Service is advising that while Saharan dust levels in T&T have slightly decreased, sensitive and affected groups should not take it for granted. 

The Met Office says a fresh surge of dust is expected to enter our area from tonight.  

In a short update, the Office says that the current decrease is due to the higher moisture content associated with the Tropical Wave expected to pass the islands later tonight. Even so, visibility is currently down to 8 km over the Northern Range and the Environmental Management Authority (EMA) indicated an Air Quality Index (AQI) of 86 (Rated - Moderate) at Point Lisas, Trinidad and 96 (Rated – Moderate) at Signal Hill, Tobago. 

The new, incoming surge will return air quality levels to unhealthy.  

This means that those with respiratory conditions, sinus issues and dust allergies are advised to ensure that relevant medication is available during the surge.
