UPDATE (3/18)!! A dangerous windstorm is producing wind gusts over 75 MPH in the Texas Panhandle and West Texas early this evening. Blowing dust is reducing visibility to below one-half mile in the Texas Panhandle, West Texas, Permian Basin, Trans-Pecos, and the Borderland. Humidity levels are below 20 percent in many of these regions, resulting in an extremely critical wildfire danger. A period of even stronger winds, possibly exceeding 80 MPH, may occur early Wednesday morning across the north
