My wife, who works with many Brazilian companies, has also told me about this one (in Spanish). Research for yourselves, and see if it checks out.

I'm from São Sebastião do Caí, Rio Grande do Sul. Our city was also devastated by the water. Anyway, this is the official page for those that wants to donate. with PIX and international options: https://sosenchentes.rs.gov.br/sos-rio-grande-do-sul

Remember. All heroes wear capes.

Is there any reliable place where we can donate to bring relief to the city?

Give me tips and what should I expect?

I've suffered through 2 floods in the past. Hope everything goes well.

I Cant believe jo lives in the same city i live! Hope that you are safe.
