28 of March Landfall at Brazil

http://www.ncdc.noaa.gov/oa/climate/res ... lcane.html

Great sat loop of Catarina first known south Atlantic Hurricane.

This storm was called "Catarina" by some meteorologists, since it made landfall south of the Island of Santa Catarina, Brazil.
This may have been the first hurricane observed in the Southern Atlantic Ocean--it certainly had a well defined eye and eyewall.
The US National Hurrican Center classified this system as a category 1 "hurricane". However, this intensity was discounted by Brazilian meteorologists, who only rated it at perhaps tropical storm intensity. No aircraft flew into this storm to measure central pressure and winds.
The closest surface reporting stations for which we received data were SBFL (Florianopolis) and SBPA (Porto Alegre). The maximum sustained wind speed reported on SBFL hourly observations was 17 knots (19.6 mph) at 28/0700Z and SBPA reported 23 knots (26.5 mph) at 28/1600Z. It looked like the eye made landfall somewhere between these two sites.

some lovely images there.I must admit that system did take everyone by suprise,but no doubts in my mind that it was a hurricane,it had a good eye(certainly not what you'd come to expect in a tropical storm system!)and also a visable eyewall.When it made landfall I believe it had gusts reaching 90Mph.A small but very nice little system and most certainly I think the first witnessed south-atlantic hurricane.Thanks cycloneye for sharing those great pics and loop.

I saw a best track and it was a category 2 hurricane at landfall with 85KT winds. Damage photos also indicate that the storm was above category 1 intensity

Or, as the Brazilians called it last year, a very strong, never-before-seen extratropical storm. I kid you not.

Nah, it was a hurricane.

Around a year ago everyone in the Scientific Community started to look more toward the subtropics of the South Atlantic Ocean. A mysterious cyclone developed near the Brazilian eastern coast and for many there was only one astonishing classification, "a hurricane." But that was impossible, it was believed the South Atlantic was completely infertile, "Catarina" proved that things are not always what they seem to be. This cyclone proved that even in inhospitable areas, if conditions come together, great and amazing things can happen.
