Tropical Cyclone Warning Bulletin Here is the latest Tropical Cyclone Warning Bulletin issued by the Hong Kong Observatory. The Standby Signal, No. 1 is in force. This means that a tropical cyclone now centred within about 800 kilometres of Hong Kong may affect us. At 9 a.m., the tropical depression over the central part of the South China Sea was estimated to be about 720 kilometres south of Hong Kong (near 15.8 degrees north 113.4 degrees east) and is forecast to move west-northwest at about 12 kilometres per hour across the central part of the South China Sea, in the general direction of Hainan Island. According to the present forecast track, the tropical depression will maintain a distance of about 700 kilometres from Hong Kong today (11 June). Strong winds are not expected generally over the territory today, but its associated outer rainbands are affecting the northern part of the South China Sea and coast of Guangdong. The Standby Signal, No. 1 will remain in force for most of the time today. The tropical depression is expected to intensify gradually and move in the general direction of Hainan Island in the next couple of days. It will then move towards the vicinity of the coast of western Guangdong. Depending on its intensity, distance from Hong Kong and the change in local wind strength, the Observatory will assess the need for issuing the Strong Wind Signal, No. 3 between later tomorrow (12 June) and Friday (13 June). With the tropical cyclone edging closer to the coastal areas, it will be windy with occasional heavy squally showers in the latter part of this week. There will be swells. Members of the public are advised to stay away from the shoreline and not to engage in water sports. (Precautionary Announcements with No. 1 Signal) 1. Precautions should be taken. Drains should be cleared of obstructions, and windows and doors should be checked. 2. People in areas of exposed to high winds or in low-lying areas should take precautions against strong winds and flooding. 3. Those who have duties during a tropical cyclone should now remain on call. 4. People planning to visit Guangdong, Macau, outlying islands or remote parts of Hong Kong should note that changes in weather may affect your trips. 5. There will be swells. You are advised to stay away from the shoreline and not to engage in water sports. 6. Fishing vessels and low power vessels in open sea should seek shelter as soon as possible and be secured properly with moorings. 7. Construction and property management practitioners should make sure that overhanging facilities and temporary structures outdoors are securely fastened, and should take precautionary measures. 8. Listen to radio, watch TV or browse the Hong Kong Observatory's website and mobile app for the latest information on the tropical cyclone.

The Very Hot Weather Warning is now in force. Under the influence of prolonged heat, members of the public should stay on the alert to prevent heat stroke or other discomforts related to very hot weather and pay due attention to health conditions. If symptoms such as dizziness, headache, nausea, shortness of breath or confusion develop, take rest and seek help immediately, and seek medical advice as soon as possible. Elderly persons, pregnant women, infants and children, those with chronic illnesses, such as heart disease or high blood pressure, as well as the obese are more vulnerable to heat stroke. Watch out for any symptoms of heat stroke. When engaged in work under hot weather or high-temperature environments, please refer to the Guidance Notes on Prevention of Heat Stroke at Work of the Labour Department and take necessary precautions. When engaged in outdoor activities, drink more water and avoid over exertion. If not feeling well, take a rest in the shade or cooler place as soon as possible. Perform outdoor activities in the morning or late afternoon. During indoor activities, replenish water timely. If there is no air-conditioning, then windows should be kept open and fans be used as far as possible to maintain adequate indoor ventilation. Public facilities with heat sheltering may also be used. Avoid prolonged exposure under sunlight. Light-coloured and air-permeable clothing, a wide-brimmed hat that covers the back of your neck and ultraviolet (UV) blocking sunglasses can reduce the chance of sunburn by solar UV radiation. Choose a broad-spectrum water-resistant sunscreen product with a sun protective factor (SPF) of 30 or higher when doing outdoor activities and apply liberally; reapply every two hours if you need to stay outdoors for a prolonged period, or after swimming, sweating or towelling off. Beware of health and wellbeing of elderly or persons with chronic medical conditions. If you know of them, call or visit them occasionally and check whether their household ventilation and air-conditioning devices function properly. Those more vulnerable to heat stroke should avoid outdoor activities and stay away from hot environment as far as possible. Stay in cool, well-ventilated or air-conditioned places.
