The likelihood of a typhoon warning signal being issued in Hong Kong over the weekend is low, as Tropical Cyclone Kujira is set to weaken under the influence of Dolphin, but airlines nonetheless cancelled at least 22 flights between the city and Japan. It would maintain a distance of about 700km (435 miles) or more from Hong Kong, and its direct threat to the city was “not high”, according to the forecaster. “With Dolphin continuing to move westwards, Kujira will move eastward towards Luzon and weaken gradually under the influence of Dolphin,” the Observatory said. “Unless Kujira adopts a track closer to the coast of Guangdong, the chance of issuing the typhoon standby signal, No 1, is rather low.” Dolphin, which had been downgraded from a super typhoon to a severe typhoon, would move westwards towards Okinawa and the East China Sea, according to the forecaster.
