Efforts from government departments were underway across town to deal with the aftermath of Typhoon Wipha, Chief Secretary Eric Chan said on Monday.

Strong winds and heavy rain from Wipha pounded the city, with the Hurricane Signal No 10 in force for nearly seven hours on Sunday.

"While the storm gradually moved away from Hong Kong, various departments have not been relaxed," Chan wrote on social media.

"Different teams have launched a new round of special inspections, including carefully checking roadside trees, external walls, signboards, slopes and construction sites, and removing dangerous structure one by one, to ensure the safety of residents."

Chan noted that he had chaired an interdepartmental meeting to ensure all relevant departments made early preparations to deal with potential threats.

"During the storm, there were more than 700 fallen tree reports across Hong Kong. The Drainage Services Department also received seven cases of flooding. All of which were handled swiftly," he said.

Chan also expressed his gratitude to those who "stayed on duty" during Wipha's arrival for their unremitting efforts in helping the city weather the storm safely.
