In Brazil, search and evacuation efforts continue for survivors of catastrophic floods in the southern state of Rio Grande do Sul as the death toll has reached at least 90 people. Over 130 people are still missing. The city of Porto Alegre has been almost entirely cut off by the flooding — the airport and bus stations are closed, while main roads are blocked. Tens of thousands have been left without a home, forced to sleep in the street, while others are fleeing to other regions on foot. Survivors are also struggling to find food and other basic necessities.
