The Potential Tropical Cyclone that has been moving northward through the Gulf of Mexico made landfall southwest of New Orleans, LA on Saturday 19 June as a minimal Tropical Cyclone. The animation of total precipitable water, above, from the MIMIC TPW website, shows that most of the storm’s moisture is east of the center. (The circulation of Pacific Tropical Storm Dolores is also apparent, making landfall near Punta San Telmo in Mexico) A percent-of-Normal plots from NOAA/NESDIS/OSPO, below, shows values about 150% of normal over much of the southeast USA. Consequently, Flash Flood Watches are in effect over much of southern Alabama northeastward into western North Carolina, as shown below.

A True-Color image from CSPP Geosphere, below, taken from this link, shows the storm inland over southwestern Alabama; much of the rain and deep moisture with the storm remains to the east of the center.
