No 1 typhoon signal may be issued between Saturday afternoon and night, as an area of low pressure is expected to intensify into a tropical cyclone and move towards the city, Hong Kong Observatory said.
The weather watchdog said on Friday that the area of low pressure over the central and southern parts of the South China Sea was intensifying, and it was expected to develop into a tropical cyclone later in the day.
According to the forecaster, the tropical cyclone could enter within 800km (497 miles) of Hong Kong on Saturday and had a higher chance of moving towards the vicinity of Hainan Island and western Guangdong province. But its movement and intensity were still “quite uncertain’.
“Depending on its movement, the Observatory will consider issuing the standby signal No 1 tomorrow afternoon to tomorrow night,” it was stated.
“Under [the cyclone’s] influence, there will be squally showers and it will be windy offshore and on high ground in the vicinity of the Pearl River Estuary on Sunday and Monday.”
For now, the forecaster said, a subtropical ridge is expected to bring very hot weather to southeastern China on Saturday with a few showers over the region. Another area of low pressure over the western North Pacific is also bringing unsettled weather to the region.
Mainly cloudy weather with a few showers and isolated thunderstorms are expected in the city on Friday, with temperatures ranging from 27°C - 32°C
Very hot weather with sunny intervals and a few showers are expected on Saturday, and squally showers and thunderstorms in the following couple of days.
香港可能於週六下午至夜間發出一號颱風
香港天文台表示，週六下午至夜間期間，預計低壓區將增強為熱帶氣旋並向市區移動，因此可能不會發出1號颱風訊號。
氣象部門週五表示，南海中部和南部的低壓區正在增強，預計當天晚些時候將發展為熱帶氣旋。
據預報員稱，該熱帶氣旋週六可能進入香港800公里（497英里）範圍內，並有較大機會向海南島和廣東省西部地區移動。 但其運動和強度仍「相當不確定」。
天文台表示，視乎其動向，考慮明日下午至明晚發出一號待命訊號。
「受（氣旋）影響，週日和週一珠江口附近離岸和高地將有狂風驟雨、大風。”
預報員表示，目前，副熱帶高壓脊預計將在周六為中國東南部地區帶來非常炎熱的天氣，並有幾場陣雨。 北太平洋西部的另一個低壓區也為該地區帶來不穩定的天氣。
預計週五全市以多雲為主，有陣雨，局地雷陣雨，氣溫27°C - 32°C
預計週六天氣非常炎熱，間有陽光和幾陣驟雨，隨後數日將有狂風驟雨和雷暴。
