Lanza pointed to a tweet from Michael Lowry, a tropical storm expert who works at the Federal Emergency Management Agency, noting that while 50-60 percent of Atlantic tropical cyclones start near Africa as series of thunderstorms, that still leaves a good chunk with other origins.

"The storm will sit over the Gulf of Mexico for a few days and may eventually become partially or fully tropical in nature during the time period from late this week into next weekend", said AccuWeather Senior Meteorologist Adam Douty.

Those warm waters will also make for a very juicy system, whether it develops into a tropical storm or not, and that means some very heavy rain is in store for the Gulf Coast.

The Mississippi River is expected to crest at 20 feet Friday night into Saturday, give or take, according to the National Weather Service. If the depression's winds reach 39 miles per hour, it would become Tropical Storm Barry.

The Flood Protection Authority said it will be closing several flood gates and structures in the New Orleans area starting Wednesday.

It isn't clear yet exactly where the storm will hit, Brink said, but models show it making landfall somewhere between Lake Charles, Louisiana and Mobile sometime Saturday.

Judge Amit Mehta sided with the pharmaceutical companies and stated, "HHS can not do more than what Congress has authorized". Another question could be whether the president wants to give Congress more authority over regulation.

Officials in New Orleans are monitoring for any potential storm surge impacts on the Mississippi River.

Regardless of the classification this system develops into, Louisiana and MS are forecast to see very heavy rain - more than a foot in some places, Brink said. This could present an imminent possibility for disaster since the levees are only capable of protecting the city from surges up to 20 feet. Additional Tropical Storm or Hurricane watches could be issued later today or tonight west of Morgan City.For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office.DISCUSSION AND OUTLOOK -- At 1000 AM CDT (1500 UTC), the disturbance was centered near latitude 28.5 North, longitude 86.4 West. This scenario would be a little more impactful for the ArkLaTex, particularly in terms of heavy rain potential for some of the area.

Even in absence of a hurricane, gusty thunderstorms and isolated tornadoes associated with a tropical depression or storm can be a threat to lives and property.

It would be the first tropical system in the United States this hurricane season.

BSEE said more than 600,000 barrels per day of Gulf oil production and 17% of the region's natural gas production was shut by producers.

Wind: tropical storm conditions are possible within the watch area by late Thursday or early Friday.
