Update, 8:50 a.m. Monday: The National Hurricane Center said this morning that an area of low pressure in the Gulf of Mexico has a 30 percent chance of developing into a tropical depression. But the cluster of showers and storms will bring heavy rain to the New Orleans area and northern Gulf Coast this week.

"Regardless of whether or not the system becomes a tropical cyclone, locally heavy rains are likely over portions of

the southeastern United States during the next few days," the NHC said.

Said WWL-TV: "Impacts for Louisiana will be higher rain chances on Sunday night, Monday and Tuesday. Rain amounts of 2-4 inches are expected, but some isolated spots could get more than that."

Original story

The National Hurricane Center is reporting that a low pressure center that formed over the Yucatan Peninsula has a less than 40 percent chance of forming into a tropical cyclone, but will produce "locally heavy rainfall" over portions of the north Gulf Coast and southeastern U.S.

"This system and a broad trough of low pressure over the western Gulf of Mexico are producing a large area of disorganized showers and thunderstorms extending from the northwestern Caribbean Sea northward over the eastern Gulf of Mexico," the NHC said in a report. "Upper-level winds are expected to be only marginally conducive for development while this system moves northward toward the northern Gulf Coast during the next couple of days."

The NHC will continue to monitor the storm.

"The Air Force Reserve reconnaissance aircraft that was scheduled for (Sunday) was canceled, but another mission is scheduled for tomorrow, if necessary," the NHC said.
