Hong Kong narrowly escaped the worst of Super Typhoon Ragasa last year when it passed within 100km rather than making a direct hit. The city weathered the storm. But the damage caused by the typhoon, with winds reaching 220km an hour at its centre, was significant.

There were storm surges and floods. More than 100 people were injured and over 1,200 trees felled. The typhoon, which prompted Observatory to issue the No 10 signal, brought the city to a standstill for nearly two days and costs were estimated to run into the billions of dollars.
Coastal areas were hard-hit as sea levels rose and waves breached barriers. Water poured into restaurants in Tseung Kwan O, causing extensive damage. The government promised to review mitigation measures in high-risk waterside locations and to learn from the experience.

The publication of guidelines to help those on the shoreline susceptible to such damage better prepare for strong typhoons is part of that process. The 46-page document, along with a brochure, provides practical advice. The guidance should be followed.

Steps have also been taken towards better defences ahead of the typhoon season. Work on flood walls at Tseung Kwan O is under way and expected to be completed this year.

Three sets of water-filled barriers are available and 50,000 sandbags are ready for deployment. This should ensure coastal areas are better protected.
