While Typhoon Talim – approaching Taiwan – is expected to intensify over the next two days, the Observatory is warning that another big storm will come near to Hong Kong.
Tropical cyclone Doksuri, which formed recently west of the Philippines, is forecast to gradually get bigger and move across the South China Sea toward Hainan Island in China, the weather bureau said.
The Observatory predicted that Doksuri will be within 800 kilometers of Hong Kong on Thursday.
Showers are expected over the coast of Guangdong in the next couple of days, it said.
The weather bureau in Macau will hoist a signal no-1 on Wednesday evening, as Doksuri on its current track will be within 800km of the former Portuguese enclave.
Meanwhile, typhoon Talim is tipped to intensify into a severe typhoon with wind speeds of more than 185km per hour – bringing heavy rain and strong winds to northern Taiwan over the next two days.
Hong Kong suffered poor air on Tuesday as various districts recorded ‘serious’ and ‘very high’ risks in air quality.

Roadside monitoring stations in Causeway Bay and Mong Kok also reached the “serious” level.
Under the influence of the dual typhoons, both general and roadside air quality monitoring stations are expected to register a “very high” risk level on Wednesday afternoon.
