Typhoon Lekima started out as a tropical depression on August 2, then quickly picked up speed as it headed northwest.
The tropical depression (essentially a group of thunderstorms) originated in the Philippine Sea. Five days later, on August 7, it morphed into a super typhoon, with a wind speed of at least 150 miles per hour.
Before making its way to China, the storm passed through the Philippines, where it caused flooding in more than 400 areas.
The storm prompted the cancellation of hundreds of flights across major airports in China.
Shanghai Disneyland was also closed due to inclement weather.

Lekima made landfall in Eastern China on the morning of August 10.
The storm's arrival triggered a landslide in the port city of Wenzhou, where a natural dam collapsed under pressure from heavy rain.
The landslide killed at least 18 people and left 14 missing.
The storm is now headed toward Shanghai, a city with more than 20 million people. Lekima is the third-largest typhoon on record in China.
