(credit: NOAA) 1:45pm ET Update: The National Hurricane Center has upgraded the disturbance in the Gulf of Mexico to Tropical Storm Imelda. The naming of the storm, which may bring some tropical storm-force winds to the upper Texas coast, does not change the fact that by far the biggest threat is heavy rainfall. Original story: It's possible that the most damaging tropical system to strike the United States in 2019 won't have a name. Although Hurricane Dorian brought widespread devastation to the Bahamas, it did relatively modest damage to the Southeastern United States.
