Tropical cyclone “Rai” has already turned moving northeast and is expected to pass within 200 km south of Macao tomorrow. The rain band associated with “Rai” will affect Macao tonight and tomorrow with frequent rain persisting for a period of time. The intensity of “Rai” has weakened further, however, it is expected to be closest to Macao between midnight and morning tomorrow.

Meanwhile, under the joint effect of storm surge and high astronomical tide, flooding is expected in Inner Harbor areas tonight. “Blue” Storm Surge Warning is in effect with expected flooding level below 0.5m. Public is advised to take precautions against flooding.
