“Bomb Cyclone”
For next week, meteorologists warn of the possibility of the formation of a so-called “bomb cyclone” in the Atlantic Ocean. This is an extratropical cyclone that gains strength very quickly. Its effects depend on how far it is from the continent.
The first forecasts indicate, however, that the “bomb cyclone” should have a trajectory away from Brazil, not passing directly through the country. On the other hand, it should be able to increase the intensity of winds in the southern region, causing storms.
