Standby Signal, No.1 was updated at 7:45 p.m. on 3 October

Issue date: 2025-10-03T11:45+00:00

Here is the latest Tropical Cyclone Warning Bulletin issued by the Hong Kong Observatory. The Standby Signal, No. 1 was issued at 7:40 p.m. This means that a tropical cyclone now centred within about 800 kilometres of Hong Kong may affect us. At 8 p.m., Severe Tropical Storm Matmo was estimated to be about 770 kilometres southeast of Hong Kong (near 17.4 degrees north 119.4 degrees east) and is forecast to move west-northwest at about 25 kilometres per hour across the central and northern parts of the South China Sea and intensify gradually. Matmo is expected to maintain a distance of about 500 kilometres or more from Hong Kong tonight (3 October) and tomorrow morning (4 October). The Standby Signal, No. 1 will remain in force until noon tomorrow. According to the present forecast, Matmo will intensify progressively and edge closer to the vicinity of Leizhou Peninsula and the eastern part of Hainan Island. Local winds will strengthen gradually later tomorrow. The Observatory will consider issuing the Strong Wind Signal, No. 3 in the early afternoon tomorrow. Depending on the intensity of Matmo, the distance of its associated gale force winds from the Pearl River Estuary and the change in local wind conditions, the Observatory will then assess the need of issuing higher tropical cyclone warning signals. Locally, it will still be very hot during the day tomorrow. Under the influence of the outer rainbands of Matmo, there will be a few squally showers and thunderstorms later tomorrow and more showers at first on Sunday (5 October). Seas will be rough with swells. Members of the public are advised to stay away from the shoreline and not to engage in water sports.
