CNN NEW ORLEANS, Louisiana (AP) -- Remnants of Hurricane Ivan swung back into the Gulf of Mexico and developed into a tropical storm Wednesday, prompting warnings in Louisiana and southeastern Texas. The storm is expected to make landfall sometime Thursday night. The remnants kicked seas up several feet, posing a threat to fragile barrier islands and their beaches in both states, and forced some offshore oil and gas crews to head home. A tropical storm warning was issued from the mouth of the Mississippi River in Louisiana west to Sargent, Texas. Ivan was upgraded to a tropical storm after sustained winds were measured near 40 mph. The Hurricane Center said the storm could strengthen before landfall. Three dozen oil platforms and drilling rigs, idled since Sept. 13 because of Ivan, remain shut down. Ivan and its remnants were blamed for at least 52 deaths in the United States and 70 in the Caribbean. Much of the destruction was caused by flooding. After hitting Florida last Thursday as a hurricane, Ivan weakened and broke apart, with most of the storm heading north to drench Southern and mid-Atlantic states. A slice of the storm turned southward, however, and dropped up to 5 inches of rain Monday on Florida before moving into the Gulf. In Texas, the emergency operations coordinator for Galveston County, Jim Billman, was anticipating a minimal tropical storm coming ashore with 50 mph winds. "We'll probably be doing everything we can to alert residents of the Bolivar Peninsula and the west end of Galveston that high tides may be elevating," Billman said. "If that thing just comes straight in, it'll probably be a tidal or rain event. It certainly bears watching. It's a sneaky one. It's just developing quickly." In Louisiana's Cameron Parish, Emergency Preparedness Director Freddie Richard Jr. said officials were keeping an eye on the storm. The swampy parish on the state's southwest corner consists mainly of marshes, cabins and camps. "We're just advising people in low-lying areas ... to prepare to move to higher ground if the tides come up," he said. Good lord! What does it take to stop this thing!?!?!
