It's a VERY difficult decision to make, because whatever it is, it will affect a lot of things
I think it would be wise to hold a meeting with all the teams participating in the Brazilian championship, and take a vote on what action to take
In addition to the lack of condition of the stadiums and the compromised infrastructure, there is the factor that practically everyone in the state is affected in one way or another, their families at risk, people involved in aid etc.
A very unfortunate situation
Apparently they will only pause the games of the affected teams. But in my opinion they will have to have a lot of time after everything is over to be able to return, precisely so that they can get back in shape and focus on the competition. But, in other times I'm sure they would have stopped the championship.
