This is Mexico's worst weather crisis since 1958, the government reports.


While Mexico continues to reel from a pair of powerful tropical systems, a new threat is emerging in the Gulf of Mexico that could bring more flooding to the storm-battered nation as well as heavy rains to portions of the U.S. Gulf Coast this weekend.

Hurricane Manuel made landfall Thursday morning just west of Culican, Mexico, on the country's west coast, the U.S. National Hurricane Center reported.

As of 5 p.m. EDT, Manuel had weakened to a tropical storm with winds of 45 mph and was crawling to the northeast at 7 mph. It was expected to continue to weaken overnight and dissipate over the mountains of Mexico on Friday, the hurricane center reported.

It is yet another blow to a country battered by the one-two punch of Manuel's first landfall on Sunday and Tropical Storm Ingrid's lashing of Mexico's east coast on Monday. (Ingrid was a hurricane offshore, but made landfall as a tropical storm.)

Meanwhile, another tropical system is bubbling up in the Gulf of Mexico, which the hurricane center says will likely become a tropical depression during the next day or two.

If it becomes a tropical storm, which means its winds would have to reach 39 mph, it would be called Jerry and would be the 10th named storm of the 2013 Atlantic hurricane season.

This storm is expected to have some impact on the U.S.: The combination of moisture from the new system in the Gulf, an approaching cool front from the northwest and some moisture from Manuel will bring both needed rain to parts of Texas but also the potential for flash and urban flooding, AccuWeather reports.



Mexico could again bear the brunt of the storm, which "will likely spread heavy rain over portions of eastern and southern Mexico and could cause life-threatening floods and mudslides over areas already impacted by torrential rain during the past several days," the hurricane center warns in an online bulletin.



Far out in the Atlantic Ocean, Tropical Depression Humberto dissipated late Thursday.

Yet another area of storminess is slowly organizing between the Bahamas and Bermuda, AccuWeather says. That area could develop into a storm that would affect Bermuda over the weekend and then potentially the Canadian Maritimes early next week.
