Wikipedia:Severe Tropical Cyclone Yasa (2020)

Severe Tropical Cyclone Yasa is currently a strengthening tropical cyclone in the South Pacific Basin. Forming into a tropical cyclone on December 12, the system produced gale-force winds as it absorbed Tropical Cyclone 01F. On the next day, the FMS upgraded the system to category 1 status and assigned it the name Yasa. Soon, the JTWS also assigned it Category 1 status.

Meteorological History
On December 11, the FMS noted Tropical Disturbance TD02F in the south Pacific. The JTWC then issued a Tropical Cyclone Formation alert as it organized in a favorable environment with radial outflow, low wind shear, and warm sea temperatures. The disturbance then began a Fujiwhara effect as it began to absorb tropical cyclone 04P. A day later, the FMS upgraded Yasa to category 1 status, followed by the JTWC. Persistent deep convection wrapped around it as its organization improved in the favorable environment.
