Storms drenched southern parts of the Chinese mainland on Monday, triggering warnings of flash floods and landslides, a day after Typhoon Wipha pounded Hong Kong.

Typhoon Wipha has toppled trees and caused major flight disruptions in Hong Kong and at some nearby airports in China as it moved west off the country’s southern coast.

The tropical cyclone made landfall in mainland China late Sunday afternoon with winds near to those of a Category 1 Atlantic hurricane.
