A new tropical storm brewing in the South China Sea forced Vietnam to suspend the search Monday for 17 fishermen missing from another storm that struck over the weekend, disaster officials in Hanoi said.

Eleven fishermen from two trawlers were reported missing from the earlier tropical storm, Conson, which hit Saturday night, disaster official Do Son in central Quang Ngai province said.

Six fishermen from another boat were reported missing after their vessel sank Friday while seeking shelter at the Paracel islands off Vietnam's coast.

Conson had earlier struck the Philippines at typhoon strength, leaving 68 people dead, and another 84 remain missing. It was downgraded to a tropical storm before it made landfall in Vietnam.

More than 600 homes were damaged and 43 boats destroyed in Vietnam, authorities said.

Meteorologists said Monday a tropical depression with sustained wind speeds of up to 61 km/h has now formed and could gather strength to become a tropical storm overnight.
