Fiction:Hurricane Katanama

Hurricane Katanama was a catastrophic Category 5 hurricane and the costliest, lowest pressure and deadliest to hit Island Snoy on record. It dealt nearly 38B$ in damage in Mino and more than 49B$ in Snoyland, as well as over 2B$ in other places combined. Its lowest pressure was 785 mbar.

Lifetime
Forming from the remnants of two hurricanes, Hurricane Isaiah and Hurricane John, as well as a tropical wave, it started off as a relatively strong tropical depression. Rapidly strengthening across the Geroseene Strait, it dealt some damage there. Strengthening to Category 2, it hit Verde Point, dealing a lot of damage and over 800 fatalities. Strengthening rapidly to category 4, it made its final landfall before category 5 in the Wider Islands before strengthening to category 5. Lingering in the ocean, moving slowly, it rapidly strengthening to its peak strength, 195 MPH (1 min). After suffering to wind shear and recovering, it headed for Island Snoy. Hitting the Lesser Peaks, it still maintained category 5 and smashed Island Snoy and the Tiny Islands in September 12, 2016. Still a category 4, it headed north toward the Greater Peaks. Then, it died off Winterwater Island in the far north.
