GUIYANG, June 23 (Xinhua) -- Rain-triggered floods killed three people and left three missing in southwest China's Guizhou Province as of 4 p.m. Sunday, local authorities said.

The heavy downpours that started Friday have caused floods in 17 counties and districts of Guizhou, affecting a total of about 455,700 residents, according to local emergency management authorities.

The floods have damaged 11,500 hectares of crops and collapsed 12 family houses. Direct economic losses were estimated at 776.5 million yuan (about 113 million U.S. dollars).

The Guizhou provincial finance department and emergency management department have earmarked 4 million yuan for disaster relief efforts in the affected areas. Tents, clothes, quilts, folding beds and other relief supplies have been dispatched to the affected residents.

The rain is forecast to last until Monday in Guizhou's western and southern parts.

In the neighboring Chongqing Municipality, 16 counties and districts have been battered by torrential rain since Saturday, with daily precipitation of more than 110 mm in the worst-hit area.

The rain caused the water levels of some rivers in Chongqing to rise above warning levels.
