On Sunday, instability intensifies and rain spreads across practically all of Paraná. Climatempo's forecast points out that the action of low pressure systems associated with the advance of the cold front favors periods of rain and showers, with the possibility of heavy rain, risk of winds, hail and thunderstorms, in addition to high accumulations, mainly in the west, north and center of the State.
