Oct. 31 (Bloomberg) -- At least 11 people are dead and six missing after Typhoon Mirinae roared across Manila and southern Luzon island before weakening into a storm and moving west of the Philippines toward the South China Sea.

Mirinae, which knocked out power, washed away a bridge and toppled trees, was 170 kilometers (106 miles) southwest of Manila as of 1 p.m. local time, according to the weather bureau. Winds had weakened to 105 kilometers an hour from 130 kilometers earlier today. “The worst is over, but we cannot be complacent,” Ernesto Torres, National Disaster Coordinating Council spokesman, said by phone.

One man drowned and his 1-year-old child is missing in Pililia province, the military said. At least seven people have died in the Bicol region, Civil Defense Director Raffy Alejandro said by phone today, and three more were killed in flash floods in Laguna, Provincial Police Commander Manolito Labador said. A man is missing in Muntinlupa City after a shanty washed into a nearby creek, Torres said.

As many as 700 families in Taytay, Rizal province, who had been evacuated from a previous storm, had to be moved again after Mirinae knocked down their makeshift shelters made of tarpaulins and other light materials, Gwen Pang, a Red Cross spokeswoman, said by phone today.

A man and his son are missing and feared drowned, after a bridge in Batangas City collapsed under their car, Police Commander Jesus Gatchalian said. The boy’s mother was rescued.

Thousands Stranded

Thousands were stranded in ports and bus stations as flooding closed some provincial roads. Some of the areas that were badly flooded after tropical cyclone Ketsana, which carried the heaviest rainfall in at least 40 years on Sept. 26, were flooded again today.

Parts of Marikina and Taguig, both in eastern Manila, were waist-deep in water, Pang said. Towns around Laguna Lake, southeast of Manila, remained “critical” because Mirinae’s winds generated strong waves, she said.

“It was furious,” said Efren Aguilar, a staff member of the disaster coordinating council at Quezon province where Mirinae, known locally as Santi, struck earlier today. “There was heavy rain and strong wind for two hours. Things have calmed down now.”

The weather bureau cut the storm signal in metropolitan Manila from three to one, the lowest level, earlier today. Manila Electric Co. aims to restore electricity within the day to most of the 1.6 million customers who lost power, and Philippine Airlines Inc. said flights have resumed. “By tomorrow, it will be safe to go out,” Torres said.

All Saints’ Day

The typhoon coincides with the All-Saints’ weekend, when many Filipinos travel to their home provinces in the archipelago of more than 7,000 islands. Holidaymakers visit cemeteries to pay respects to their ancestors during the three-day weekend.

The Philippines has been battered by more than 10 cyclones this year. More than 121,000 people remain in evacuation centers in the wake of cyclones Ketsana and Parma in the past month. Hundreds were killed in floods and landslides, and farm damage forced the world’s biggest importer of rice to schedule a supply auction for this week.

Rice-producing regions in central and northeastern Luzon were spared this time, said Frisco Malabanan, national rice program director. Some rice crops may have been damaged in Camarines Sur and Mindoro provinces, and any damage in Batangas would be minimal, Malabanan said.

Vessels weighing more than 1,000 gross tons may sail by tomorrow, Coast Guard Commandant Admiral Wilfredo Tamayo said. “While the typhoon is here, travel has to be stopped,” Tamayo said by phone.

As many as 800 people were killed in June last year when Typhoon Fengshen slammed into the Philippines. Ketsana left about 80 percent of Manila, a city of almost 12 million people, underwater.
