An area of non-tropical low pressure has shown enough tropical characteristics to be upgraded to Subtropical Storm Karen.

A hybrid system, a subtropical storm features tropical and non-tropical elements.

A system that’s tropical strengthens due to warm temperatures in the ocean, while a non-tropical storm gets its strength from differences in the atmosphere’s temperature and pressure. (RELATED: Shockwaves From Typhoon Halong May Cause Unusually Strong Storm For US West Coast)

Subtropical Storm Karen is creating thunderstorms near its center, and though it includes characteristics that are tropical, fronts connected to the system are not letting it become completely tropical, according to the National Hurricane Center (NHC).

Karen has 45 mph maximum sustained winds and is headed northeast at 9 mph through the North Atlantic, an unusual place for tropical development and far from the tropics.

As the Daily Caller previously reported, across the United States in the Pacific Ocean, a potential bomb cyclone is headed towards Alaska due to the powerful impacts from the remnants of Typhoon Halong, which could bring the state hurricane-force winds. Then, the remnants will head towards the Western United States to possibly bring heavy rain and snowfall to the region.

Halong was a Category 4 storm at its peak, and neared Tokyo while slicing off the coast of Japan.
