JACKSONVILLE, Fla. – The tropical storm that formed Saturday off south Florida is strengthening over the warm Gulf waters is expected to approach the Gulf Coast on Monday night with high winds and a life-threatening storm surge. At 8 a.m. Monday, Tropical Storm Sally has 65 mph sustained winds and was centered about 115 miles east southeast of the mouth of the Mississippi River. The National Hurricane Center said dangerous storm surge was possible along the northern Gulf Coast starting on Monday and added hurricane conditions could set in there early Tuesday. A tropical storm watch was extended westward from the Okaloosa/Walton County line in Florida to the Alabama-Florida line. Tropical Storm Rene weakened in recent hours and was reclassified as a tropical depression.

JACKSONVILLE, Fla. – The tropical storm that formed Saturday off south Florida is now a Category 1 hurricane over the warm Gulf waters. Sally is expected to approach the Gulf Coast on Monday night with high winds and a life-threatening storm surge. At noon on Monday, data from a NOAA Hurricane Hunter aircraft investigating Sally indicated the system has rapidly strengthened to a hurricane, with maximum sustained winds of around 85 mph with higher gusts. Sally has 65 mph sustained winds and was centered about 115 miles east southeast of the mouth of the Mississippi River. The National Hurricane Center said dangerous storm surge was possible along the northern Gulf Coast starting on Monday and added hurricane conditions could set in there early Tuesday.

Instead, Hurricane Barry mixed up the waters, making the dead zone smaller than expected, scientists said during a National Oceanic and Atmospheric Administration press conference on Thursday. A dead zone is an area in the ocean that has a low amount of dissolved oxygen. That's well below the 8,717 square miles some predicted, or the slightly smaller dead zone of 7,829 square miles that NOAA predicted. The largest dead zone in the Gulf of Mexico formed in 2017 and covered nearly 9,000 square miles. But it "does not mean we achieved a tremendous amount of success," improving the environment that creates these dead zones, Northey said.

NEW ORLEANS - Barry made landfall as a Category 1 hurricane early Saturday afternoon along Louisiana's central coast, then immediately weakened back into a tropical storm, according to the National Hurricane Center. But it was the rainfall that always posed the greatest threat, regardless of whether the storm was a hurricane or a tropical storm. And a tropical storm warning was discontinued for anyone east of the mouth of the Mississippi River. Storm surge warnings along the coast extended from Intracoastal City, south of Lafayette, to Biloxi, Mississippi, and along Lake Pontchartrain. For the first time since their construction, all major floodgates on the Mississippi River are closed, he added.

Tropical Storm Barry is now threatening to blow ashore as a hurricane, packing drenching rains "that could test the flood-control improvements made in New Orleans since Hurricane Katrina 14 years ago," the Associated Press said Thursday.

JACKSONVILLE, Fla. - A low-pressure system that moved into the Gulf of Mexico late Tuesday was upgraded this morning to a potential tropical cyclone. The National Hurricane Center expects the system, located about 155 miles east southeast of the mouth of the Mississippi River at 2 p.m. Wednesday, to strengthen into a tropical storm by Thursday. The five-day NHC forecast calls for this system to be a tropical storm by Thursday afternoon and a Category 1 hurricane by Saturday morning as it nears the western Louisiana coast. This system has the potential to produce heavy rainfall along portions of the northern and eastern U.S. Gulf Coast later this week. Interests along the Gulf Coast from the Upper Texas coast to the western Florida peninsula should monitor the progress of this system.

2007: The I-35W Mississippi River bridge spanning the Mississippi River in Minneapolis, Minnesota, collapses during the evening rush hour, killing 13 people and injuring 145. The NTSB later cited a design flaw as the likely cause of the collapse, and asserted that additional weight on the bridge at the time of the collapse contributed to the catastrophic failure.
