HONG KONG – The Hong Kong Observatory canceled all tropical cyclone signals and issued the Strong Monsoon Signal at 3:40 pm on Tuesday, as Typhoon Nesat continued to move away from the city.

Although Tropical Cyclone Nesat has departed from the coast of Guangdong, under the influence of the intense northeast monsoon, it remains windy over the territory with strong winds offshore and occasional gale winds on high ground.

At 4 pm, Nesat was centered about 510 kilometers south-southwest of Hong Kong and is forecast to move west-southwest at about 15 kilometers per hour towards the seas south of Hainan Island.

"Although Tropical Cyclone Nesat has departed from the coast of Guangdong, under the influence of the intense northeast monsoon, it remains windy over the territory with strong winds offshore and occasional gale winds on high ground," the HKO said.

Locally, temperatures in the afternoon were generally about ten degrees lower than those of Monday, said the Observatory, adding that it will be cloudy with occasional rain and appreciably cooler.

Nesat will move across the seas south of Hainan Island, towards the vicinity of Beibu Wan and weaken gradually in the next couple of days, the HKO said.

Seas will be rough with swells. The HKO advised members of the public to stay away from the shoreline and not to engage in water sports.
