Port Isabel, Техас

Areas of fog are expected to develop across portions of Deep South Texas and the Rio Grande Valley overnight and into the early morning hours. Pockets of reduced visibility, generally 1 to 3 miles, with locally dense fog to a mile or less are likely. Should model guidance and observations from station data and webcams indicate rapid development of more widespread dense fog, a Dense Fog Advisory may be issued overnight for portions, or all of, the region. Use caution if traveling as visibility may change rapidly in a short amount of time. Use low beam headlights and leave extra distance between your vehicle and others on the road.
