The Meteorological Office in Dominica is warning residents to take action to prevent illnesses that are associated with Sahara dust which is now affecting the island.

“A thick plume of Saharan dust haze is expected to continue to blanket the island chain over the next few days resulting in dry conditions and a significant reduction in visibility,” Marshall Alexander. “People with respiratory illnesses, allergies etc, should take the necessary precautions to minimize complications – precautions such as staying indoors and taking measures to keep the dust outside of your homes and avoiding outdoor activities.”

The Met Office is also recommending the wearing of masks, keeping medication close at hand and using air purifiers where they are available. Small craft operators are also being advised to stay in port particularly in cases of vessels on which GPS is not being used.

According to Alexander, while the Sahara dust will help suppress the development of Tropical systems in its vicinity during the period for which it is present, the prediction for an above-normal hurricane season still stands. He said that a gradual reduction in dust haze can be expected by late Tuesday into Wednesday.

Meanwhile, the Met Office is reporting that by late Wednesday into Thursday, a tropical wave is projected to generate an increase in showers and possible thunderstorm activity, across the Lesser Antilles.

The Met Office also says that a high-pressure system is expected to result in occasional cloudiness with a few showers, across the area, during the next 24 hours. Windy conditions are expected to persist today.

Moderate to rough seas are also expected during today, with waves peaking near 10.0ft. Small craft operators and sea bathers, particularly on the east coast, are advised to exercise extreme caution, as a small craft warning and a high surf advisory are in effect.

    i suspected that you know. This dust might cause weather systems this hurricane season to rise up quicker as it is kind of like a greenhouse effect keeping the atlantic warmer ass opposed to if it havd no clouds of dust over it. im no scientist, but it might be possible. Wind levels have risen with the passing sand over the weekend. look out for plenty action in the next few weeks.

      @72nations, I don’t know what part of the world you are but I will tell you this is nothing to do with greenhouse effect all rubbish where I am in southern Spain we get Sahara dust every once in a while coming from the African continent into Europe mostly Spain nearby at nights if it rains in the morning our cars would be dirty with sand dust no problem just washed it off.

        Im not saying that it is caused by greenhouse effects. Spain is right next to Africa so off cource you will get it yearly. What i am saying is the immense amount of clouds of sand can have similar effects to greenhouse over the atlantic as the water continues to be heated. On my side of the world it has gotten more humid since we started to expecience this in the last few days. the heat is there but its not intense on your skin. Like i said im not a scientist, and i might be talking rubbish as you pointed out, but lets wait and see if we do get any serious systems this hurricane season. Already we expect to have storms this weekend, and im not surprised either.
