Don't try to control damage while the storm is raging.
It may be tempting to make immediate repairs or reinforcements, but please wait until the storm is over. Some of the people who died in the typhoons of 2004 were swept off roofs while they were trying to make repairs. A typhoon may cause a sudden blast of wind even when it is far away, and the danger increases greatly as the storm approaches. Rather than last-minute measures, the best policy is to gradually reinforce roofs and walls during good weather.
