MANILA—Filipinos in Hong Kong were urged Saturday to prepare for typhoon Mangkhut, locally known as Ompong, as it heads for the Chinese territory.

This, as the typhoon makes its way out of the Philippine area of responsibility after leaving behind a trail of destruction and thousands of Filipino families in makeshift shelters.

More than 227,000 Filipinos in Hong Kong were instructed by the Philippine consulate general to stay indoors and defer any planned travels or outdoor activities, the Department of Foreign Affairs (DFA) said in a statement Saturday.

Consul-general Antonio Morales further advised Filipinos to monitor weather bulletins and heed instructions by local authorities.

Morales added that, in the event a storm signal of T8 or T10 is raised, the consulate will be closed and all passport appointments and other transactions scheduled on Monday will be accommodated any time during the consulate's business hours.

Other activities and events scheduled that day will also be canceled and rescheduled should the alert level be raised.

Filipinos in Hong Kong can call 999 or the Consulate Hotline at +852.9155.4023 in the event of an emergency.
