Rare South Atlantic Storm Forms - No Threat to Land

For just the 7th time since the satellite era, we have a south Atlantic tropical/subtropical cyclone. The system (designated 90Q) has had Dvorak Classifications of 2.5ST and 2.0 Tropical today and a uncontaminated 35KT winbarb from ASCAT last night.

The system is no threat to land, but a statistical oddity for the South Atlantic, considering the rarity of storms developing in the area.

Of note: there was 1 sytem in the 70's one in the 90's and now 5 since 2000. Additionally the designation Q is now being used to designate South Atlantic Storms.
