An analysis of various forecasting models indicated that the effect of this cloud of Saharan dust mixed with SO2 will reach the easternmost region of the island this Tuesday and will extend to the entire Cuban territory, according to the state site Cubadebate. .

According to the forecasts of the Atmospheric Monitoring Service of the Copernicus Program (CAMS) of the European Union, the highest concentrations of SO2 over Cuba will be recorded from the level of 850 hPa (1500 masl).

Given the annual arrival of dust on the island of the Sahara, the Cuban Society of Allergy and Asthma has recommended that people with these problems stay as long as possible in their homes to reduce their exposure to these particles.

The presence of dust from the Sahara is common on the island between the months of June and August. Its influence hinders the formation of tropical cyclones but increases the sensation of heat and intensifies the drought, one of the main climatic problems that the island has had to deal with in recent years.

Minerals, mites, viruses, bacteria and other pathogens carried by the cloud increase the risk of diseases, especially in asthmatic and allergic patients.

Particles in clouds also affect terrestrial and marine ecosystems, especially coral reefs, as well as fruit, rice, sugar cane and legume crops.

Today it is recalled that at the end of June 2020 the dry air of the Sahara desert reached the Cuban archipelago with a dense dust cloud that significantly deteriorated air quality in much of its geography.

In addition, it significantly raised temperatures, breaking maximum records in the western province of Artemisa and eastern areas such as Gran Piedra and Pinares de Mayarí.
