Tammy weakens into post-tropical cyclone but is still packing hurricane-force winds
After spending five days as a hurricane, Tammy has finally weakened, according to the latest advisory from the National Hurricane Center.
At 5 a.m., Tammy has been classified as a post-tropical cyclone, but still producing hurricane-force winds several hundred miles east-southeast of Bermuda.
No further advisories will be issued on Tammy.
However, the National Hurricane Center said it is possible "Tammy could reacquire tropical characteristics this weekend or early next week."

As of Wednesday, Tammy had been a hurricane for five days. That's the most hurricane days by an Atlantic storm getting named after Oct. 17 since Hurricane Sandy in 2012.
It's also tied for fifth-longest since the satellite era began in 1966, according to Philip Klotzbach, Colorado State University meteorologist specializing in Atlantic basin hurricane forecasts.
Rapid intensification: Scientist says rapidly intensifying hurricanes 'particularly concerning' for coastal communities
The Florida Division of Emergency Management said while Tammy poses no direct threat to Florida over the next five days, breezy conditions and ocean swells will continue along the East Coast due to the pressure difference between a system of high pressure along the eastern U.S. and distant Tammy.
Hurricane Otis strikes Acapulco as one of the strongest storms ever to hit Mexico
Acapulco, Mexico, endured one of the strongest storms on record to hit the country from the Pacific Ocean when Hurricane Otis made landfall early Wednesday as a Category 5 hurricane with 165-mph winds.
The full extent of damages, along with the number of potential injuries and deaths, remains unclear due to communications disruptions and the main highway into Acapulco being impassable.
Videos on social media and television footage Wednesday showed hotels, restaurants, streets and bridges to be mostly underwater. Large buildings and other structures had missing walls and roofs.
Otis blew up from a tropical storm with 70-mph winds to a Category 5 hurricane with 165-mph winds in 13 hours, advisories from the Hurricane Center show.

Who is likely to be impacted by Hurricane Tammy?
The Florida Division of Emergency Management said while Tammy poses no direct threat to Florida over the next five days, breezy conditions and ocean swells will continue along the East Coast due to the pressure difference between a system of high pressure along the eastern U.S. and distant Tammy.
Elsewhere, the forecast calls for:
Surf: Swells will continue to affect portions of Bermuda, the northern Leeward Islands, the British and U.S. Virgin Islands, and Puerto Rico during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions.
Forecasters urge all residents to continue monitoring the tropics and to always be prepared.
