As Hurricane Leslie heads north toward Bermuda, a leftover portion of Hurricane Isaac has found its way back to the Gulf of Mexico, where it's threatening to become a new tropical storm.
After making landfall in Louisiana on Aug. 27, Isaac dumped rain as it moved up the Mississippi Valley and then "was ripped in half" as it curved eastward, according to meteorologist Jeff Masters of WeatherUnderground.com.
"One portion of the storm moved over the Northeast U.S., bringing heavy rains there" - including several days of rain in the Philadelphia area - "and another portion sank southwards over Alabama," he explained in his blog.
That southern portion has moved back into the Gulf of Mexico, where it has a 40 percent chance of becoming a new tropical storm, according to the NHC. The elongated area of low pressure is centered about 75 miles southeast of the mouth of the Mississippi River has been drifting southward.
Since shower activity with the low remains poorly organized, an Air Force reconnaissance mission scheduled for today has been postponed until Friday, according to the NHC. There is still potential for some development during the next day or so before environmental conditions become unfavorable.
Because the surviving portion was not the primary remnant, such a storm would get a new name, Masters said. The next one is Nadine.
Leslie could become a Category 2 storm before nearing Bermuda on Sunday. Its projected path should take it north toward Nova Scovia, sparing the U.S. East Coast, according to the National Hurricane Center.
Michael, moving northward far out in the Atlantic, has become the seventh hurricane this season - the earliest seventh hurricane since 1893, say the NHC. It's also the year's first Category 3 hurricane.
The Isaac remnant is the only system that poses a threat to become a tropical cyclone in the next 48 hours.
