he National Hurricane Center in Miami estimated the storm was a full-fledged, Category I hurricane with central winds between 75 mph and 80 mph (121 kph to 129 kph), making it the first hurricane in the South Atlantic in recorded history. Brazilian scientists however, have disagreed, saying the storm had top winds of 50 mph to 56 mph (80 kph to 90 kph), far below the 75 mph (121 kph) threshold of a hurricane.
