Shortly afterwards, the Macao Special Administrative Region also announced that it would hoist the Typhoon Signal No 1 by Wednesday afternoon.

Hong Kong is expected to be windy and see squally showers on Friday and Saturday as Saola may edge closer to the Pearl River Estuary, according to the present forecast track.

The tropical cyclone may make landfall over Guangdong or move westwards across the coastal waters of Guangdong, in light of the uncertainty cast by the influence of northeast monsoon over the cyclone’s track and intensity.
