A Macau chief executive has discretionary powers to suspend casino operations in emergencies, including typhoons, though the powers have been used sparingly. Some Macau casino operators have occasionally opted to suspend some non-gaming facilities during typhoons, an example being amid Typhoon Tapah, at the start of this month. The advent of Super Typhoon Ragasa saw Signal No. 8 or above is issued, public bus services in Macau and the light rapid transit rail system are suspended. Disruption to sea transport began on Monday, with ferry services between Macau and the Chinese mainland affected.
