Post The Fujiwhara Effect
The Fujiwhara effect, sometimes referred to as Fujiwara interaction or binary interaction, is when two nearby cyclonic vortices orbit each other and close the distance between the circulations of their corresponding low-pressure areas. The effect is named after Sakuhei Fujiwhara, the Japanese meteorologist who initially described the effect. Binary interaction of smaller circulations can cause the development of a larger cyclone, or cause two cyclones to merge into one. Extratropical cyclones typically engage in binary interaction when within 2,000 kilometres (1,200 mi) of one another, while tropical cyclones typically interact within 1,400 kilometres (870 mi) of each other



North Atlantic
Hurricane Iris of the 1995 Atlantic hurricane season interacted with Hurricane Humberto, before interacting and absorbing Tropical Storm Karen during September 3.[8] In 2005, the remnant low of Tropical Depression Thirteen moved northward and then northeastward around a non-tropical low located to the north of the system. It briefly strengthened into Tropical Storm Lee. Thereafter, Lee weakened back to a tropical depression as it moved northeastward and northwestward around the eastern side of the non-tropical low and eventually absorbed the non-tropical low.[9] In the same year, Alpha was absorbed by Wilma. On 5 October 2016 Hurricane Matthew began interacting with Tropical Storm Nicole in a Fujiwhara relationship.


In wikipedia already.

A small affect was seen with the two cyclones that approached Hawaii a month or so ago.

Not surprising this happens. Can't isolate forces.
