Rescuers still can't reach at least 90 Guatemalan villages cut off by mudslides after Tropical Storm Stan.
At least 508 people are dead, but officials say another 1,400 could have died in two villages in the worst affected area, around Lake Atitlan.
Hundreds of rescue workers have been digging through thick mud in a search for survivors which is being held up by more heavy rain.
Stan killed another 100 people across Central America and Southern Mexico.
As the search goes on, the lashing rain brings the threat of more landslides.
Colombia and the US have said they will send food, blankets and first aid equipment to help victims in Central America and Mexico.
Stan was a Category One hurricane when it hit land on Tuesday.
But despite being downgraded to a tropical storm by the end of the day, it set off landslides and widespread flooding.
