Rare South Atlantic Storm Forms - No Threat to Land
      #87384 - Wed Mar 10 2010 05:55 PM

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.

The attached file is the visible satellite image from about 1700 UTC

I was also noticing that on the NRL Tropical Cyclone Webpage, and almost posted. Seems we're having more of those with the gradual warming of that basin, in that hemispheres' summer season. Nice report ... Thank You !!
