On the forecast track, the center of Barry will move through southern Louisiana today, into central Louisiana tonight, and into northern Louisiana on Sunday.
Life-threatening Tropical Storm "Barry" is moving closer to the coast of Louisiana and is expected to make landfall along its south-central coast later today (CDT), most likely as a Category 1 hurricane.
At 09:00 UTC on July 13, the center of Tropical Storm "Barry" was located about 90 km (55 miles) SW of Morgan City, Louisiana and 260 km (165 miles) W of the mouth of the Mississippi River.
Its maximum sustained winds were 100 km/h (65 mph) and minimum central pressure 933 hPa. The system was moving WNW at 7 km/h (5 mph).
A motion toward the northwest should begin soon, followed by a turn toward the north tonight or Sunday.
On the forecast track, the center of Barry will make landfall along the south-central Louisiana coast later today. After landfall, Barry is expected to move generally northward through the Mississippi Valley through Sunday night.
Strengthening is forecast before landfall, and Barry is expected to be a hurricane when the center reaches the Louisiana coast later today.
Steady weakening is expected after Barry moves inland.
Tropical Storm #Barry is an unusual storm. In addition to being asymmetrical, #NOAA20’s instruments couldn’t see a convective core last night. This would ordinarily prevent strengthening, but Barry is forecast to attain hurricane status before making landfall in Louisiana. pic.twitter.com/Ja92NJgPNz— Joint Polar Satellite System (JPSS) (@JPSSProgram) July 12, 2019
Circulation within #TropicalStormBarry is much more apparent in this #GOESEast loop from around 10 a.m. ET. As the storm bears down on the #GulfCoast, heavy rainfall and storm surge remain the biggest threats.

I really like @Weathernerds's interface for overlaying GLM lightning w/ #GOES16 visible imagery for Barry. The most active lightning is associated with a feeder band SW away from the center.— Philippe Papin (@pppapin) July 13, 2019
Pay closer attention to lightning on the SE flank, closer to where the mesovortex is at. pic.twitter.com/vKKgeorZ4h
1. There is a danger of life-threatening storm surge inundation along the coast of southern and southeastern Louisiana, portions of Lake Pontchartrain, and portions of coastal Mississippi where a Storm Surge Warning is in effect. Water levels have already begun to rise in these areas, with peak inundation expected to occur later today. The highest storm surge inundation is expected between Intracoastal City and Shell Beach.
2. The slow movement of Barry will result in a long duration heavy rainfall and flood threat along the central Gulf Coast, across portions of the Lower Mississippi Valley and north into the Tennessee Valley through the weekend into early next week. Flash flooding and river flooding will become increasingly likely, some of which may be life-threatening, especially across portions of southeast Louisiana into Mississippi.
3. Hurricane conditions are expected along a portion of the coast of Louisiana, where a Hurricane Warning is in effect. Tropical storm conditions are expected elsewhere along much of the Louisiana coast and inland across portions of the lower Mississippi Valley where tropical storm warnings are in effect.
