Tropical cyclone “Saola” is moving westward towards the Pearl River Estuary with increasing speed. Since it is forecasted that “Saola” will pass within 30 km of Macao in early hours of 2nd Sept., and under the influence of the circulation of “Saola”, the wind in Macao will significantly strengthen, and SMG will consider issuing Tropical Cyclone Signal No.10 between 1am and 3am on 2nd September. It is forecasted that the wind in Macao will be strongest in early hours on 2nd Sept. and will reach between Beaufort scale level 10-12 with gusts, and there will be frequent heavy showers and thunderstorms. In addition, due to the influence of strong rainbands near the center of “Saola”, there will be heavy showers and thunderstorms in the next few days, and the rain will be quite heavy at times on 2nd and 3rd Sept.

Meanwhile, since “Saola” will be very close to the Pearl River Estuary, it will lead to additional water level increase according to the latest storm surge forecast. Combined with the influence of astronomical tide, it is forecasted that flooding will occur starting early hours of 2nd Sept., and it is possible that flood level will reach between 1.5 and 2 meters in the morning, and water level may rise rapidly in a short period of time.

“Saola” is expected to have a significant impact on Macao. The public are advised to stay safe and pay attention to the latest weather information.
