China, July 1998 - Seasonal summer rains have devastated vast areas of China this year, killing more than 2,000 people, destroying 2.9 million houses and ruining more than 9 million hectares of crops.
During the first week of August new rains in central Hubei and Hunan provinces pushed water levels of the Yangtze to a third peak and cut power supplies to Hubei's provincial capital Wuhan where water levels have risen to 1.25 meters above danger level. Towards the end of July torrential rains lashed central China causing the first serious flood.
