Rains pelted Rio again on Wednesday, a day after the heaviest deluge on record sent killer mudslides cascading down hillsides and turned streets into raging torrents in Brazil's second-biggest city. The death toll increased to 100 in Rio and the neighboring city of Niteroi, while children were kept from schools for a second straight day and authorities continued to urge people to stay at home, AP reported. "The situation improved (Wednesday)," Rio Mayor Eduardo Paes told GloboNews TV. "But the less people are on the streets, the better. People should not go out if they don't have to." The city remained on alert amid fears the continuing rains could dislodge saturated ground and cause more slides, Paes said. Authorities reported 104 people injured and 65 missing. Although the sun began emerging in some areas, pockets of heavy rains continued to cause trouble. Some roads were still underwater, and a Copa Libertadores match between Flamengo and Universidad de Chile was postponed until Thursday because of flood damage at Maracana stadium. Officials said potential mudslides threatened at least 10,000 houses in the city of 6 million people. Some 1,200 people were left homeless.
