Residents across Antigua and Barbuda are being advised to take precautions as another surge of Saharan dust has reduced air quality to moderate levels, according to the Antigua and Barbuda Meteorological Service.

The bulletin, issued at 12:30 p.m. on Wednesday, says the decline in air quality is being caused by elevated concentrations of fine particulate matter (PM2.5 and PM10) associated with the 14th notable Saharan dust event to affect the country this year.

The Air Quality Index (AQI) is forecast to remain between 51 and 80, placing conditions in the Moderate category and triggering a Level II Air Pollution Alert through Friday.

While air quality remains acceptable for most people, the Meteorological Service warns that those who are unusually sensitive to air pollution could experience health effects. People with asthma and other respiratory illnesses, heart disease, older adults and young children are considered the most vulnerable.

The advisory recommends that active children and adults, as well as anyone with respiratory conditions, limit prolonged outdoor exertion while the dust lingers over the islands.

Although the overall health risk is considered low for the general population, the Met Office cautioned that some pollutants may pose moderate health concerns for a very small number of people who are especially sensitive to poor air quality.

Residents are encouraged to stay informed by following updates from the Antigua and Barbuda Meteorological Service through its website, social media platforms, and local radio and television stations.

Forecasters expect the Saharan dust plume to continue affecting Antigua and Barbuda until Friday before conditions begin to improve.
