Meteorological history
The tropical depression that was to become Severe Tropical Cyclone Evan was first noted by the Fiji Meteorological Service (FMS) on December 9, while it was located within the South Pacific Convergence Zone near the Fijian dependency of Rotuma. At this stage, the system's broad low-level circulation was poorly organised, while the majority of atmospheric convection was fragmented and located over its northeastern quadrant. Over the next day, the system subsequently moved south-eastwards within an area favourable for further development, with low vertical windshear, sea surface temperatures of 29 - 30 C and favourable outflow. During December 11, the systems low-level circulation centre started to rapidly consolidate, as it passed around 55 km to the southwest of the French Territory of Futuna. Later that day as the depression became equivalant to a tropical storm and develop a small eye on microwave imagery, the United States Joint Typhoon Warning Center initiated advisories on the system and designated it as Tropical Cyclone 04P. This was followed by the FMS naming the system as Evan during December 12, after it had become a Category 1 tropical cyclone on the Australian tropical cyclone intensity scale.

Tonga
On December 12, the FMS issued a tropical cyclone alert for the Tongan Islands Niuatoputapu and Niuafo'ou as it was thought that Evan might cause gale-force winds over the islands within 48 hours. During December 14, the alert was cancelled as Evan was no longer predicted to pass close enough to the islands to produce gale force winds or any damage on either island.
