Casino gross gaming revenue (GGR) in Macau in September rose 6.0 percent year-on-year, to about MOP18.29 billion (US$2.28 billion), showed data released on Wednesday by the city’s Gaming Inspection and Coordination Bureau. In late September, the city’s casinos had to suspend temporarily their operations for 33 hours, due to the passage of Super Typhoon Ragasa. Macau’s weather forecasting service had raised the highest tropical storm warning – Signal No.10 – in the early hours of September 24 as Super Typhoon Ragasa was at its closest to Macau. The city has five levels of tropical storm warning. The Macau authorities downgraded the maximum storm signal to Signal No.8 at 4pm on September 24, and lowered it to Signal No.3 at 11pm.
