Haze hanging over Houston is African dust cloud from Sahara Desert

That cloud of haze over Houston the past two days traveled over 4,000 miles to get here.

According to Meteorologist Travis Herzog, it's an African dust cloud that moved out of the Sahara Desert over a week ago. These dust clouds are known to reduce tropical activity as they cross the Atlantic, and if they make it here, they've also been known to aggravate heart and lung conditions.

The fine particles of dust can reach deep into your lungs, and this can aggravate existing heart and lung conditions, like heart disease and asthma. Pollution monitors detected unhealthy levels of the African dust yesterday, and we will likely see the same again this afternoon.

Children, the elderly, and those with heart and lung conditions are most susceptible to the dust and should minimize time outdoors while also reducing prolonged or heavy exertion.

We are expecting the hazy African dust to move out tomorrow as deep tropical moisture blows in, setting the stage for a chance of weekend rain showers.
