Is a remnant of Hurricane Isaac about to give birth to a tropical storm? The National Hurricane Center says there's a 40 percent chance of that, and it plans to send a monitoring aircraft into the system Friday to get a better idea.
The system "has a medium chance, 40 percent, of becoming a tropical cyclone during the next 48 hours," the center said in an advisory Thursday afternoon.
Already producing rain, the system is centered about 75 miles southeast of the mouth of the Mississippi River, and slowly drifting south.?
A hurricane that deteriorates only to have a remnant redevelop into a tropical storm is not unheard of -- Ivan in 2004 was one case -- but it is unusual, Weather Channel meteorologist Jon Erdman reported.
"A?funny thing happened to this remnant," he wrote in describing what's brewing.?"Basically, the polar jet stream was never able to catch up" and whisk it away northward along with the rest of Isaac.
If a tropical storm does form it will not keep the name Isaac and instead would be Nadine, the next name on the official list.
Hurricane Michael became the first major Atlantic storm of 2012, while Hurricane Leslie continued to slowly move northward Thursday morning. Michael was not expected to make landfall, but Leslie was already creating waves in Bermuda. NBC's Brian Williams reports.
That's because the remnant in the gulf is only a small piece of the former hurricane. When a weakened Ivan regenerated into a tropical storm the name was kept because most of Ivan was still intact.
Isaac's daughter would be only the second time on record where a system regenerated along with a new name.
"This is the only example that we can find in the modern era where the partial remains of a system went on to regenerate and, so, get a different designation," National Hurricane Center meteorologist Todd Kimberlain told the Associated Press.?
The only other time? In 2005, a remnant from a tropical depression that dissipated near Puerto Rico eventually became part of a new depression -- which became the catastrophic Hurricane Katrina.?
This time, however, any new storm's impact will likely be minimal, Erdman stated.
Most of the rain could stay over the Gulf of Mexico "until it's kicked east or northeastward ... this weekend," he wrote. "Good news for those recovering from Isaac's surge and rainfall flooding in Louisiana and Mississippi."
