MIAMI (Reuters) - The remnants of deadly Hurricane Ivan, which rampaged through the Caribbean and then into the U.S. Gulf Coast a week ago, killing more than 100 people, have reformed in the Gulf of Mexico as a tropical storm threatening the Texas and Louisiana coasts.

By 8 a.m. EDT on Thursday, Ivan was about 95 miles southeast of Cameron, Louisiana, with top winds of 45 mph, the U.S. National Hurricane Center said.

It was moving west-northwest at about 15 mph on a course that would likely take its core ashore on the northeastern Texas coast in the next day, the center said.

Ivan could strengthen before coming ashore and was expected to dump as much as 10 inches of rain in its path.

Ivan, at one point one of the most powerful Atlantic hurricanes on record, made a devastating 10-day trek through the Caribbean before hurtling ashore in the United States near Gulf Shores, Alabama, just west of the Florida Panhandle.

Ivan first formed as a tropical storm on Sept. 2. It killed 69 people in the Caribbean, causing widespread devastation to the islands of Grenada and the Cayman Islands, and at least 45 in the United States, where it ripped up seaside buildings and smashed bridges on the Alabama and Florida coasts.

Its remnants, which caused flooding as far north as Pennsylvania over the weekend, regenerated in the Gulf of Mexico on Wednesday into a tropical storm.

dang, maybe the Big Easy gets smacked by Ivan after all.
