The Hong Kong Observatory has said that it would issue the T1 storm warning when Tropical Cyclone Trami enters within 800 metres of the city late on Thursday night or early on Friday morning. “Trami is forecast to move west in the general direction to the vicinity of Hainan Island and intensify gradually,” the Observatory said at noon on Wednesday. “Under the combined effect of Trami and [a] northeast monsoon, it will be windy and become cloudy with a few showers over the coast of southern China on Friday and over the weekend.
” The likelihood of a Strong Wind Signal No. 3 being raised would depend on “the movement of Trami and the change in local wind conditions,” the Observatory said, adding that there were “uncertainties in the subsequent movement and intensity of Trami.” The weather in Hong Kong is forecast to deteriorate over the weekend, following generally fine conditions.
Highs of 31 degrees Celsius are predicted for Friday, with the average temperature for October to date reaching 27.9 degrees, more than a degree higher than the mean for the month recorded from 1991 to 2020, which was 25.7 degrees Celsius.
The No.1 signal is the “Standby” signal. It is issued when a tropical cyclone is centred within about 800 kilometres of Hong Kong and may affect the territory.
