The Observatory on Sunday said it would cancel all cyclone warning signals at 2.20 pm, as Typhoon Danas moves further away from Hong Kong.

It said while the Standby Signal No.1 was in force on Sunday morning, the storm had moved faster in a north-easterly direction.

However, the Observatory advised people not to let their guard down.

"There will still be swells. Members of the public should stay on the alert, stay away from the shoreline and not engage in water sports," they said.

The Observatory said it will be extremely hot this afternoon, and there could be showers and squally thunderstorms triggered by the high temperatures.

It said the very hot weather was expected to remain for at least a couple of days.
