It doesn't happen often -- but the South Atlantic is firing up a tropical cyclone off of the Brazil coastline. This storm is a bit late to the Carnivale (it having ended a week ago down in Rio) but a rare South Atlantic tropical cyclone is definitely worth posting about as an appetizer for those in northern climates who like to track tropical weather up here. The last tropical storm to develop in the South Atlantic was last January -- known as Anita -- and weakened before landfall. This system is poised to move away from the South American coastline but throw thunderstorms and rain back towards Rio and the coastline for a day, perhaps two, as it intensifies on its eastward drift.
Those of you who follow computer guidance and have heard of the GFDL (which is used to guide tropical cyclone development) know that it has a tendency to overdo intensification. It is trying to turn this system into a 85 mph hurricane (cyclone for Southern Hemisphere folk) as it moves away from Brazil over the next couple of days. Such intensification is doable before the system turns to the south and begins to get sucked into a storm system tracking across the "Roaring Forties" of the Southern Hemisphere, but at minimum this system definitely has the potential of developing into a decent tropical storm.
