Saharan Dust Expected in Coastal Bend this Week

CORPUS CHRISTI, TX – The Texas Commission on Environmental Quality (TCEQ) forecasts that air quality in Corpus Christi will be impacted this weekend due to the arrival of Saharan dust.

On Saturday, June 28, the leading edge of the Saharan dust plume is expected to reach Corpus Christi by midday, bringing a noticeable increase in fine particulate matter (PM2.5). Air quality is forecast to reach the middle of the “Moderate” range, meaning that individuals in sensitive groups, such as those with respiratory conditions, may experience health effects.

By Sunday, June 29, higher concentrations of dust and elevated humidity levels may lead to continued moderate air quality, with PM2.5 and PM10 levels remaining in the middle to upper “Moderate” range. Hazy skies and reduced visibility are also possible.

Impact on Public Health

The presence of the Saharan dust can pose various health risks, especially for vulnerable individuals such as children, the elderly, and those with pre-existing respiratory conditions like asthma, chronic bronchitis, or allergies. The dust particles are very fine and can penetrate the respiratory system, potentially causing or exacerbating respiratory problems. The dust may carry allergens and irritants, triggering allergic reactions and respiratory discomfort in sensitive individuals.

During a Saharan Air Layer event:

•Stay informed. Watch for alerts from the National Oceanic and Atmospheric Administration (NOAA) and local media outlets.

•Limit outdoor activity. If outdoor activities cannot be avoided, wearing an N95 mask is recommended. The mask protects against inhaling dust particles and other particulate matter.

•Drink plenty of water to stay hydrated. The dry and dusty conditions may lead to increased water loss through respiration.

•Monitor Indoor Air Quality. Staying indoors with windows and doors closed will reduce dust particle infiltration. Using an air purifier with a HEPA filter may also help improve indoor air quality.
