ELDORADO DO SUL, Brazil (AP) — More heavy rain is forecast for Brazil’s already flooded Rio Grande do Sul state, where many of those remaining are poor people with limited ability to move to less dangerous areas.

More than 15 centimeters (nearly 6 inches) of rain could fall over the weekend, according to the Friday afternoon bulletin from Brazil’s national meteorology institute. It said there is also a high likelihood that winds will intensify and water levels rise in the Patos lagoon next to the state capital, Porto Alegre, and the surrounding area.
