Thai government officials say the death toll from the country's worst flooding in more than 50 years has reached 602.

The officials said Sunday the flooding, that began in late July, continues to affect at least 17 provinces.

The situation has improved dramatically in recent days and residents of Bangkok were cleaning up during a “Big Cleaning Day” campaign launched by the city.

Sunday saw blue skies, dry weather and hundreds of people with brooms sweeping mud and debris from homes, while teams of volunteers removed rotting piles of garbage from the streets, as flood waters finally began receding from the center of the capital.

Thai government officials say flood waters have been receding steadily and that most streets in Bangkok, should be dry in two weeks.
