East China put on alert for Typhoon Yagi

As Shanghai braces for its third typhoon in a month, experts are blaming the extreme weather in eastern China on an unusually strong belt of atmospheric high pressure that has been moving northward since July.

Shanghai's Meteorological Service has issued yellow alerts - the third level of China's four-tier color-coded warning system - for heavy rains and thunderstorms, with Typhoon Yagi expected to make landfall in Zhejiang province on late Sunday night.

The area was already battered by typhoons Ampil on July 22 and Jongdari on Aug 3.
