A No 1 typhoon warning will remain in force on Saturday, the Hong Kong Observatory has said, adding that the chance of issuing a higher signal is “rather low”.

The forecaster also issued a very hot weather warning at 6.45am, with temperatures in some districts expected to reach 35 degrees Celsius (95 Fahrenheit) or above on Saturday and Sunday.

“The circulation of [tropical cyclone] Danas is relatively small. Unless it intensifies significantly and adopts a track closer to the Pearl River Estuary, there will not be strong winds generally over the territory,” it said.

According to the forecaster, Danas will move slowly over the northeastern part of the South China Sea and skirt about 400km (248 miles) southeast of Hong Kong for the rest of Saturday and Sunday morning.

Danas, which means “to experience” or “to feel” in Tagalog, is expected to accelerate northeastwards in the direction of the western coast of Taiwan to the vicinity of the Taiwan Strait.
