2015 Singapore Outbreak

This outbreak in Singapore was one of the deadliest outbreaks in Chinese history. At least seven twisters tore near and/or into Singapore, but only one was rated anything higher than F0, however, when four F0s hit downtown, at least $20 million in damages were tallied from one F0 overall--the most of any F0 tornado, or any tornado rated lower than F2, to be precise, in world history.

F3 tornado
This tornado was the only tornado rated any higher than F0 and one of only 3 tornadoes to actually hit land [all tornadoes began in the water], but unlike the others, this one wasn't breif. It was actually up to 1/3 of a mile wide, as when it hit, at least 30 boats were shredded. All homes in the path were deroofed, and at least 13 subdivisions were hit by this tornado, causing the high death toll and the high damage rating as well. Most of the people killed were motorists who couldn't see the tornado when it hit a tiny portion of the downtown area, further contributing the death toll when the tornado was at F1 strength. When it was over, it left at least 2,500 homes with F2 damage or higher in at least 13 subdivisions, at least 6,400 homes were damaged as well. Within just 30 minutes, it tracked a measly 4.63 miles, killed 21 people, left about 100 injured, as 15 of those deaths were in automobiles, five were on a fishing boat when the tornado initially formed and capsized it, and winds were rotating up to around 160 miles per hour.

There has been some serious debate whether to put it at F3 or F4 strength, because so many homes recieved F4 damage. However, it's been downgraded to F3 because of how slow the tornado moved, and every single home in its path was subject to those levels of damage due to prolonged wind exposure. Although some sources say it was an official F4, and possible F5 [if it was an F5, it'd be the first in China's history], prolonged wind exposure due to slow movement guaranteed downgrading to an F3 tornado.
