Tropical Cyclone Winston was reported to be the strongest storm in recorded history for the Southern Hemisphere, after hitting Fiji with maximum sustained winds of around 297 km/h (185 mph). It was also the first recorded Category 5 cyclone to make landfall in Fiji.

At least 18 people were reported to have died, hundreds of properties were destroyed and approximately 80% of the nation's 900,000 people lost power.

The Metop-B AVHRR infrared images show Tropical Cyclone Winston after it had passed over Fiji. The storm initially formed northeast of the islands and circled round them before making landfall on 20 February.

Figure 1 (above right) is the Metop-B AVHRR IR image with the ASCAT winds overlaid, from 21 February 21:34 UTC. Figure 2 is the comparison between the standard infrared and the enhanced infrared from the same time. The enhanced image shows the cloud top temperatures, with the colder clouds shown in blue to red (the coldest tops were 180 K).
