In a move to preserve the safety of workers and passengers alike, the Salgado Filho Airport serving the city of Porto Alegre, the capital of the Brazilian State of Rio Grande do Sul, has announced it would be suspending all operations until further notice, Agencia Brasil reported. The Gaúcho State is going through a heavy storm and subsequent floods that have already left nearly 40 people dead and the number is expected to grow given the number of persons still unaccounted for.
