Red dust, carried by low-level winds from west Texas, blanketed homes and cars in Louisiana and Alabama Thursday. Joel Schexnayder, a forecaster with the National Weather Service, said plowing in western and northern Texas, and possibly New Mexico, had stirred up the dust. He explained there had been little rain in the Rio Grande Valley and Big Bend areas, and a rapidly moving cool front had picked up the brick-red dust and carried it east. Officials with the state Health and Hospitals Department say the dust does not pose a health hazard.
Winds from the front, which also prompted thunderstorm warnings and tornado watches Wednesday night, gusted up to 35 mph (56 km/h) and kept the dust suspended until rains brought it down, coating everything from Lake Charles.
