Allergies giving you trouble this week? Mold isn't the one to blame!

A more subtle irritant has been plaguing South Texas

By Kaiti Blake - Meteorologist

SAN ANTONIO - Are you one of the many folks across South Texas battling itchy eyes and a case of the sniffles this week? The culprit actually hasn't been our typical problem allergen: mold.

In fact, mold has been in the low category since Monday: 

Monday 08/19 - LOW; 390

Tuesday 08/20 - LOW; 140 

Wednesday 08/21 - LOW; 170

Thursday 08/22 - LOW; 330

Rather, the reason for your sneezin' over the past several days is due to a plume of Saharan dust

This dust, made of very, very fine particulates of minerals, travels across the Atlantic Ocean from the Sahara desert region of Africa. It's transported by the trade winds, near the Earth's equator. 

It's not uncommon, especially in the summer months, for plumes of dust to make it to South Texas. The dust can give the sky a hazy look, and can also be irritating for those sensitive to allergens or to those with a respiratory condition. 

Good news: The Saharan dust will begin to thin out Thursday, and will move out of Texas by the weekend.
