NEW: Philippine Red Cross chairman will travel to stricken region Monday

Emergency officials are distributing food rations, blankets and mosquito nets

Officials estimate 100,000 are displaced

They are investigating reports that an entire village was swept away

Manila, Philippines CNN  — 

Tropical Storm Washi moved away from the southern Philippines early Monday, but not before leaving behind a wake of destruction and at least 652 people dead, according to the Philippine Red Cross.

Military and disaster officials said the vast majority of the dead were found in the port cities of Iligan and Cagayan de Oro, many of them swept away as they were sleeping. Water-logged bodies from washed-away villages floated at the shoreline, on the northwestern coast of Mindanao island.

The provinces of Compostela Valley and Zamboanga del Norte were also hit, added Benito Ramos, chairman of the National Disaster Risk Reduction and Management Council.

Defense Secretary Voltaire Gazmin said officials are investigating reports that an entire village was swept away.

Philippine Red Cross Chairman Richard Gordon will travel to the stricken region Monday to assess the damage, according to a statement from the organization.

Southern Philippines hard-hit

Authorities have started distributing food rations for some 10,000 families affected by the storm, while also handing out thousands of blankets and mosquito nets, the Red Cross said.

Flash flooding overnight Friday – following 10 hours of rain – fueled the devastation, compounded by overflowing rivers and tributaries. As much as 20 centimeters (8 inches) of rain fell within 24 hours in some areas.

Ramos said despite government warning, some did not evacuate.

An estimated 100,000 people are displaced, according to the Department of Social Welfare and Development.

At least 20,000 people were staying in 10 evacuation centers in Cagayan de Oro, Social Welfare Secretary Dinky Soliman said Saturday.

Some 20,000 soldiers embarked on search-and-rescue operations, the military said.

Officials asked for volunteers to pack food to send to those displaced.

U.S. Secretary of State Hillary Clinton expressed her condolences on behalf of the U.S. government and said the United States “stands ready to assist Philippine authorities as they respond to this tragedy.”
