Amid an approaching Tropical Wave, the public is also urged to watch out for another bout of Saharan Dust.

The Trinidad and Tobago Meteorological Service said in an update Thursday that there is a moderate concentration of dust in the atmosphere, with decreased visibility across the Northern Range.

The Met Office said the dust should "increase significantly" from Friday June 19 and that this would last for the next four to five days. 

"Dust Update (18th June) The Saharan dust is back! It is a mostly sunny morning in Piarco but there is a moderate concentration of Saharan dust in the atmosphere decreasing the visibility over the Northern Range as seen in image 1."

"It is expected that the concentration of Saharan dust will increase significantly from tomorrow Friday 19th June. This should last for at least the next four to five days."

"As shown in images 2 & 3 the concentration of Saharan dust varies from one location to another."

"Currently the Environmental Management Authority records an Air Quality Index (AQI) of 95 (Moderate) for Point Lisas Trinidad. Signal Hill Tobago has an AQI of 121 (Sensitive Groups). As such, persons who are sensitive to these changes in air quality are advised to take the necessary precautions."
