HONG KONG – The Hong Kong Observatory said it will consider raising Typhoon Signal No 1 on Tuesday night as Tropical Cyclone Ma-on is expected to move closer to the city.

In a weather advisory, the Observatory said the tropical cyclone will move across the vicinity of the northern part of Luzon and Luzon Strait on Tuesday.

The local weather will deteriorate significantly and winds will strengthen gradually on Wednesday, the Observatory said

“It is expected to come within 800 km of Hong Kong tonight. The Observatory will consider issuing the Standby Signal No.1 then,” the HKO said.

It said the forecast track and intensity of Ma-on remained uncertain as it passes through northern Luzon, but after entering the northeastern part of the South China Sea, it is expected to move northwestwards, edging closer to the coast of Guangdong. 

The local weather will deteriorate significantly and winds will strengthen gradually on Wednesday, the Observatory said.
