African dust arrives in RGV; might aggravate allergy problems

A touch of the Sahara will fill Brownsville’s skies starting today.

Matthew Brady, a meteorologist with the National Weather Service at Brownsville, said a dust layer called the Saharan Air Layer, which originates from the Saharan Desert in western Africa, has been making its way across the Atlantic Ocean and through the Caribbean toward the Rio Grande Valley.

The large brown haze that can be seen from satellite images released by the National Oceanic and Atmospheric Administration stretches thousands of miles.

However, one unpleasant effect of the dust is a possibly increased chance for allergy problems.

The Texas Commission on Environmental Quality has upgraded air quality to moderate for the Brownsville-McAllen area through Saturday.
