Dust in your face! Al­so your nose, mouth and lungs. But that’s the pe­ri­od which T&T is in, un­der siege from Sa­hara dust plus smoke from bush fires caused by the long dry sea­son.

“The Sa­hara dust will be with us un­til about Wednes­day, but it’s nor­mal for this time of year,” me­te­o­ro­log­i­cal of­fi­cer Bag­wan­deen Ram­datt said yes­ter­day.

The Met of­fice yes­ter­day chart­ed a dust haze in­dex of 32 de­grees C for Trinidad and 31 de­grees C for To­ba­go.

Ram­datt ex­plained that the dust from the Sa­hara desert “ trav­els on low-lev­el trade winds across the ocean reach­ing the Caribbean and some­times even Cen­tral Amer­i­ca. The dust wall can be thick­er or thin­ner de­pend­ing on wind speed. If the speed is strong, the haze will be thin­ner.

“Al­so, if winds are strong, it moves out of an area faster but if winds are mod­er­ate, it re­mains in the area—as with Trinidad and To­ba­go—a lit­tle longer. We had the ex­pe­ri­ence last year and it’s oc­cur­ring again, sim­i­lar­ly thick like last year when wind speed was al­so very low and the haze was thick then al­so”

Ram­datt said the dust has be­come an an­nu­al re­cur­ring fea­ture. How­ev­er, apart from dust clog­ging the at­mos­phere and re­duc­ing vis­i­bil­i­ty, he said the over­all sit­u­a­tion has been com­pound­ed by smoke from bush fires around the coun­try. San Fer­nan­do Hill was al­most whol­ly ob­scured by haze and smoke on Sat­ur­day.

In view of the sit­u­a­tion, the Met Of­fice is­sued an ad­vi­so­ry to peo­ple suf­fer­ing from res­pi­ra­to­ry dis­eases.
