Active Southern Hemisphere

By: MAweatherboy1 , 11:43 PM GMT on February 13, 2012

The Southern Hemisphere is certainly active tonight. The biggest concern right now is Cyclone Giovanna. Giovanna has made landfall on the island nation of Madagascar. Thanks to an eyewall replacement cycle and a little bit of dry air and shear, Giovanna weakened some before landfall, but still was extremely dangerous, probably with winds of at leat 130mph. This storm certainly has potential to cause significant damage and loss of life on Magagascar. Luckily, the storm is moving so it will not take too long to get out of Madagascar. The trip over this mountainous country will take a toll on Giovanna, and it will weaken significantly. It will reemerge over the Mozambique Channel and have a brief period to restrengthen slightly over those warm waters before hitting Mozambique, a country fresh off serious impact from powerful Cyclone Funso. Giovanna now ranks as the strongest cyclone in 2012 so far.

Meanwhile, Cyclone Jasmine is still clinging to life in the South Pacific. While it has been very overlooked thanks to the more threating Giovanna, Jasmine has been impressive in its ability to stay alive for quite a long time. Jasmine is still at minimal tropical storm strenth,but it is actually looking better now than it has in a while, with the convection back over the center, and I would not be surprised to see it strengthen some in the next day or so. It will probably be 4 or 5 days before Jasmine finally meets her demise. As I noted in my previous blog, Jasmine remains no threat to any land area.

Lastly, the Southern Hemisphere also has an invest on its hands right now. The Joint Typhoon Warning Center has issued a Tropical Cyclone Formation Alert for the system. It recently has had a huge blowup of convection with some very cold cloud tops, so I would not be surprised to see it classified if it can maintain this. Regardless, it, like Jasmine, is not a threat to land areas right now.
Thanks for reading and have a nice rest of the week. We already made it through Monday :D

Thanks for the comments Korithe and SPL... The trend of longer lasting storms this year has been interesting for sure

I too noticed the extreme longevity of Jasmine. In fact, most tropical cyclones this year have lasted for at least five days; perhaps we will finally return to a more normal global ACE total in 2012.
