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.

Typhoon Wipha slammed ashore along the southern Chinese coast Sunday evening, after drenching Hong Kong and Macau with heavy rain and whipping wind, the Guangdong meteorological service said.
