With a maximum wind speed of 72 kilometers per hour at its center, the fourth typhoon of the year was in waters 690 km southeast of Cangnan county in Zhejiang province at 10 am on Sunday, the center said.

It said the typhoon was moving northwest at 15 to 20 km/h and is expected to make landfall on the coast between Zhejiang and Fujian provinces on Monday night.

"The cyclone will quickly weaken after it lands," the center added.

Gales will strike some areas in Jiangsu, Zhejiang and Fujian provinces as well as Shanghai and Taiwan from Sunday to Tuesday, and vast stretches of Zhejiang and Fujian will be battered by downpours for two days starting Monday, it said.
