Saharan Dust Expected in Coastal Bend This Weekend

City of Corpus Christi

CORPUS CHRISTI, TEXAS — (News Release) The Texas Commission on Environmental Quality (TCEQ) reports that a moderate plume of Saharan dust may arrive as early as June 28th afternoon over portions of the lower Coastal Bend, enhancing the concentration of inhalable particles. The effect is expected to last through this weekend.  

The Saharan Air Layer is a mass of dry, dusty air that forms over the Sahara Desert. During the peak period of late June to mid-August, dust is blown out of Africa and into the North Atlantic Ocean every three to five days.  

Impact on Public Health  

The presence of the Saharan Air Layer 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.
