As of Thursday morning, Kate has lost its tropical characteristics.

Kate became the fourth tropical system to reach hurricane strength during the 2015 hurricane season after it strengthened early on Wednesday morning.

During its time as a hurricane, Kate left its mark in history by becoming the latest on record for a hurricane to form so far northwest in the Atlantic basin.

Kate will continue to race to the north and east across the northern Atlantic on Friday.


Shipping and fishing interests should be prepared for rough seas between Bermuda and Atlantic Canada through Thursday.

"Kate could bring strong gusty winds and heavy rain to the United Kingdom and Ireland later this weekend into early next week," AccuWeather Tropical Weather Expert Dan Kottlowski said.

An area of disturbed weather moved northward from the Caribbean Sea late last week and organized into a tropical depression on Sunday.

Tropical Depression 12 became Tropical Storm Kate on Monday morning near the Bahamas.

Kate brought rain squalls and gusty winds to the eastern islands of the Bahamas on Monday, before speeding away to the north.

Tropical Depression 12/Kate became the first tropical system in the Atlantic since Joaquin pounded the Bahamas about a month ago.

Kate could prove to be the last gasp for the 2015 Atlantic hurricane season, which officially ends on Nov. 30.

"Besides Kate, we see no support for other tropical development across the Atlantic Basin through the middle of November," Kottlowski added.

Strengthening westerly winds and cooling waters bring the demise of tropical systems as the month progresses.

Following this threat, the basin may be finished churning up tropical storms and hurricanes, aside from perhaps a poorly organized drenching system in the Caribbean or Gulf of Mexico.

Including Kate, there have been 11 tropical storms and four hurricanes, two of which became major hurricanes during the 2015 season. All numbers were all below the average of 12 tropical storms, six hurricanes and three major hurricanes.

Joaquin, which blasted the Bahamas and sent tropical moisture into the Southeastern states, stopped just short of being a Category 5 hurricane. Tropical storms Ana and Bill were the only two systems to make landfall in the U.S. Content contributed by AccuWeather Senior Meteorologist Alex Sosnowski.
