Subtropical Cyclone Karen Develops in North Atlantic

A non-tropical system in the North Atlantic has been recognized as subtropical cyclone Karen due to its significant tropical traits. This mixed system features elements from both tropical and non-tropical storms, which is somewhat unusual.

While Karen shows some characteristics typical of a tropical storm, it’s still influenced by various fronts that prevent it from being fully classified as one. As of now, maximum sustained winds are clocking in at 45 mph, with the cyclone moving northeast at 9 mph—an area not known for traditional tropical development.

In a different part of the Atlantic, Tropical Storm Jerry is struggling, particularly around the Leeward Islands, facing challenges from wind shear. Currently, Jerry’s maximum sustained winds reach 60 mph, and while it’s moving northwest, a tropical storm warning is in effect for parts of the northern Leeward Islands.

In the Pacific, remnants of Typhoon Halong are heading toward Alaska, which might bring hurricane-force winds to the state. Eventually, these remnants could also impact the western United States with heavy rain and possibly snow.

Halong was a powerful Category 4 storm while making its way near Tokyo, Japan, and its remnants are set to cause noteworthy weather changes in the U.S. All this activity during hurricane season, which concludes on November 30, is unexpected for this time of year, especially as typhoons can form in the western North Pacific at any moment.
