23 September,2013 – The No. 8 Northwest Gale or Storm Signal, was issued at 6:40 p.m.
This means that winds with mean speeds of 63 kilometres per hour or more are expected from the northwest quarter.
At 11 p.m., Severe Typhoon Usagi was centred about 90 kilometres northeast of Hong Kong Observatory (near 22.9 degrees north 114.7 degrees east) and is forecast to move west or west-northwest at about 22 kilometres per hour and continue to cross the coastal areas of Guangdong.
Usagi will be closest to Hong Kong in the next few hours, skirting within 100 km to the north of Hong Kong. Gales are blowing over many places of Hong Kong, reaching storm force over offshore waters and high ground, with gusts reaching hurricane force.
Currently the sea levels over parts of the territory have exceeded 0.5 metre above normal tide levels. Due to the storm surge induced by Usagi, the sea levels are expected to be about 0.5 to 1 metre above normal tide levels.Storm surge and heavy rain brought by Usagi may cause flooding in low lying areas. West to northwesterly winds are now affecting Hong Kong and some parts of the territory are sheltered. However, winds are expected to turn to the southwest tomorrow morning; currently sheltered areas will become exposed. The public should continue to be on the alert, and complete measures against high winds and flooding.
In the past hour, the maximum sustained winds recorded at Cheung Chau, Star Ferry and Lau Fau Shan were 90, 75 and 74 kilometres per hour respectively.
Precautionary Announcements with No. 8 Signal
- Complete all precautions in your home. Lock all windows and doors, fit bars into position and insert reinforced shutters and gates if they are available. Adhesive tape fixed to large window-panes in exposed positions will reduce damage by broken glass. Storm water drains should be cleared of leaves and rubbish.
- Do not stand near windows on the exposed side of your home. Move all furniture and valuables away from these areas. Make sure you have a safe place to shelter, should windows be broken.
- Since seas are very rough and there are swells, you are advised to stay away from the shoreline and not to engage in water sports.
- Flights at Hong Kong International Airport may be affected by the weather. Please contact your airline for the latest flight information before departing for the airport.
- Owners of neon signs are reminded that they should now arrange for the electricity supply to their signs to be cut off.
