The Hong Kong Observatory will consider issuing the No 8 signal between 4pm and 7pm on Thursday, as Super Typhoon Yagi continues to strengthen and edge closer to the city.
“Yagi is a mature storm. Under the influence of its outer circulation, local winds generally strengthened this morning with occasional gale winds on high ground,” the forecaster said.
Classes were suspended at kindergartens and special schools on Thursday as the No 3 signal remained in force.
According to the Observatory, Yagi is expected to skirt 300km (186 miles) to the southwest of Hong Kong on Thursday night and Friday morning.
“Gales associated with Yagi are set to edge closer to the Pearl River Estuary later today. Local winds will strengthen further and weather will deteriorate,” it said, adding the warning might be issued between 4pm and 7pm.
