The Philippines disaster agency has said that more than 1,000 people are missing from a storm and flash floods last week.
This sharply raises the number of victims unaccounted for as the true extent of the disaster becomes known.
Typhoon Washi and the flash floods it caused on the southern island of Mindanao are known to have killed 1,080 people, the national disaster agency said.
The agency said yesterday that dozens of people were missing but today it revised that figure to more than 1,000, saying more complete data has come in and people are reporting the disappearance of relatives.
Most of the casualties are in the cities of Cagayan de Oro and Iligan, where hundreds of thousands of people are displaced.
Many of them are sheltering in schools, churches, gymnasiums and an army base.
Benito Ramos, head of the national disaster agency, said authorities have expanded the search in light of the new tally of missing and because some bodies have been found on shores nearly 100km from the disaster area.
"We've deployed helicopters to help navy ships scour the seas further away," Mr Ramos told reporters.
The number of missing was put at 1,079, he said.
The disaster has caused damage of 1bn pesos (€17.5m) to highways, bridges, schools and other infrastructure, the agency said.
Mr Ramos said the situation for survivors is slowly getting back to normal although the displaced need sustained help.
Two navy ships and aircraft from the main island of Luzon have been deployed to help in the search and relief operations, he said.
