South Atlantic Hurricane Season?

Currently there is not a hurricane season in the Southern Atlantic, that could change. In recent years there have been a few storms that have affected Brazil. The NHC in Miami is now taking notice to these storms and will most likely start tracking them when they form (which is a rarity for now).

Previous Storms

There has been an estimated 92 storms in the years between 1957-2008. Below is a list of the more notable storms:

March 1974 Cyclone: 30mph
The storm came of the Amazon and strengthened in the presence of low wind shear and relatively warm water.


1991 Angola Storm: unknown winds
A weak Tropical Storm formed off the coast of Angola according to satellites. It is the only South Atlantic storm to form in the Eastern part.




January 2004 Cyclone: 35mph/ 1003mb
A small area of low pressure formed into a depression for a short while until wind shear began to weaken it. It moved ashore and caused heavy rain and flooding.




Cyclone Catarina (2004): 100mph/ 972mb
This is the only recorded cyclone in the South Atlantic. It formed and rapidly strengthened to a Category 2 cyclone before making landfall in the Santa Catarina State killing between 3-10 people and causing millions of dollars in damages to Brazil. People were in utter shock that a hurricane formed in the Southern Atlantic and the locals named it Catarina after the state it hit.




February 2006 Storm: 65mph
A Quickscat scan found TS force winds in this storm and it was over generally warm waters. Wind shear eventually tore the system apart.




January 2009 Storm: 40mph
This storm moved right off the coast of Brazil and Uruguay and it hovered there for a while causing 14 deaths , heavy rainfall and an Emergency being declared for 4 cities.




Tropical Storm Anita (2010): 50mph/ 995mb
An extratropical storm developed tropical characteristics and for the first time the NHC payed attention to it. They classified it as Low SL90. It was declared a Tropical Storm March 10th and became extratropical again March 12th. Its ACE index was estimated at 2.05. Local officials in Brazil named it Anita. ** This was the first storm that the Hurricane Center and agencies in the USA tracked a storm in the Southern Atlantic**




November 2010 storm: 1005mb
A cold-core system developed some subtropical characteristics until it ran aground in Brazil/Uruguay causing lots of damage.




Subtropical Storm Arani (2011): 50mph/ 989mb
The Navy Hyrdrographic Center and the Brazilian Navy started tracking a storm and classified it as Subtropical. It was named by the agency above on March 15th. Wind shear caused the death of the system.

**The picture of Arani was deleted because it caused the page to load very slowly**

There is not currently a season for South American cyclones. However, if one were to be made, it would most likely stretch from November 1 to April 30 because thats when most of the storms have formed and its opposite of the Northern Hemisphere. More data may need to be collected and more storms may need to form for anything to be put in place but its just something to think about. Thanks for reading and I hope to have a new entry up soon.

I didn't realize there were that many storm formations in that basin. I have heard of Catarina and one other that has left my memory, but that total of over 90 surprised me. Thanks Logan.

I agree with Kori, what I would give to see another Catarina to track, that would be amazing.

Good post.

Thanks :P and yes it would be interesting

Very good post.

As to "earlier" years it might be that just as the Northern Atlantic activities were not covered prior to SATs over the Eastern Atlantic (except for ship reports)Atlantic activity was under/un reported by ¿¿10%,15%??, Dr. Masters had a blog on that recently.

I had never even thought about the discrepancy between the north and south Atlantic basins with respect to hurricane formation.Now I know more than I did. Thanks, Doppler.

Thanks, I would definitely would like to have the opportunity to track another Catarina. That and to learn more about the South Atlantic cyclones and the environment they are in.

Well to the point blog about this. My question is if Brazil is the only country that designate the names for that basin?

Well, I think as of right now where ever the storm hits, they name it. If it were to only affect Uruguay then they would name it UNLESS the Brazilian government create an agency for Tropical Cyclones

I read it earlier but didn't comment as probably not as knowledgable as most and def not for S Atlantic storms. But do wonder, with what seems to be weather pattern changes, do you think...or any real sign...that the patterns changing will make it a big problem down there in the near future!? I mean, some patterns have been off. If they end up permanent, will they change the weather and wind patterns down there enough to give them a proper cyclonic season?! And the repercussions of that, being they've not been used to them to have the building codes and/or infrastructure for them...could be so devestating.

aside from that, nice blog and interesting!

Thanks for ur feedback and I think it as a problem as u said because Southern Brazil and Uruguay aren't used to hurricanes so yes there will be some bad damage.

Well done, I enjoyed the information and images. Some of those, I remember following here, and learning about the associated rarity of the events. Its good to learn about other areas, we all come out ahead.

These storms are pretty rare but becoming more often lately.
I like your pictures Doppler... Thanks for the entry.
