SAN ANTONIO
A large cloud of Saharan dust is forecasted to affect air quality in South Texas this weekend, marking the most significant occurrence of the year. The edge of the dust cloud is anticipated to reach Texas around noon on Sunday and will continue to advance into the San Antonio, Hill Country, and Austin areas by Sunday evening.
According to the Texas Commission on Environmental Quality, the arrival of this dust cloud will lead to hazy skies and moderately polluted air quality in San Antonio. Residents, particularly those with sensitivities to dust and air pollutants, are being advised to limit outdoor activities during this period. The American Lung Association has noted that individuals suffering from chronic lung diseases, such as asthma or COPD, could face heightened risks of complications due to dust exposure.
Dust exposure symptoms can affect anyone, even those without pre-existing health conditions. In light of this, experts recommend protective measures to reduce exposure, including staying indoors, using high-quality masks, maintaining air filters in homes, and keeping an eye on any symptoms that may arise.
The KENS 5 Weather Team has declared Weather Impact Alert Days for both Sunday and Monday, indicating that the effects of the Saharan dust will be closely monitored. In addition, forecasts suggest further rounds of dust may be on the horizon, with residual effects expected to linger until July 4.
Origins and Path of the Dust
The current Saharan dust plume has spread over 2,000 miles across the Atlantic, reaching into the Caribbean. This dusty air is classified as the Saharan Air Layer, which carries heated, dry, and powdery air from the Sahara Desert. Measurements indicate a high aerosol optical depth of 0.55 in the Caribbean, signaling heavier impacts on air quality are likely as the plume moves westward.
By Thursday, the dust cloud is projected to reach the Texas Gulf Coast, potentially affecting other states such as Louisiana, Mississippi, Alabama, and Florida by Friday. While respiratory irritation is a common side effect of exposure to Saharan dust, it is worth noting that this phenomenon can also serve to suppress hurricane activity by creating unfavorable atmospheric conditions for storm development.
Frequency of Saharan Dust Events
Occurrences of Saharan dust typically take place multiple times each summer, with the current event being closely monitored for developments. Weather experts and health officials are committed to providing continuous updates regarding the situation as it evolves.
As the weekend approaches, it’s advisable for residents of South Texas to prepare for declining air quality and stay informed about any further weather announcements or health advisories relating to the Saharan dust clouds.
