(CNN) -- The death toll from a tropical storm that tore through the Philippines this week has doubled.
The country's National Disaster Coordinating Council reported Thursday that 36 people died from Tropical Storm Conson. The previous death toll, reported Wednesday, was 18.
More than 40 people remained missing as of late Thursday, the council said.
The tally of damaged houses also increased from 500 to 11,230. More than 900 houses have been destroyed.
Conson, known locally as "Basyang," started as a typhoon before weakening to a tropical storm and making landfall late Tuesday.
At least four children died from the storm, including three who were struck by falling trees, authorities said.
The storm is expected to move northwest of the Philippines by Friday morning. Conson is likely to move into southern China on Friday, but the Joint Typhoon Warning Center is predicting little or no intensification before landfall there.
Heavy rain and flooding will be a concern for southern China.
