 After fluctuating in strength, the cyclone peaked with maximum sustained winds of 205 km/h (125 mph) and a minimum barometric pressure of 933 mbar (hPa; 27.55 inHg) on December 21, making it an intense tropical cyclone based on the intensity scale utilized by Météo-France.Shortly after, wind shear strengthened as Amara tracked southeast, resulting in a weakening phase.The shearing effects caused the cyclone to rapidly decay, and by December 23, Amara was determined to have degenerated into a remnant low.
