south atlantic Subtropical Storm Cari

[Somerset Squall]

The southern hemisphere seems to be on fire with the cyclone formations so far this March, with now the second subtropical storm of the year to be declared in the South Atlantic (Bapo was the first last month). Subtropical Storm Cari is located just off the south coast of Brazil, and has winds of 45kts. The storm is slowly heading south, away from the coast. The majority of Cari's rainfall is located in a band way out to sea. There is some convection associated with the LLCC, which is near Santa Catarina, producing some rainfall. As Cari moves slowly south then southeast out to sea, it should weaken as it moves over progressively cooler waters (sea temps beneath Cari are currently about 26C). The system is not expected to transition into a fully tropical cyclone, though it can't be ruled out.

Convection is becoming more concentrated near the centre of Subtropical Storm Cari as it lingers off the coast of Brazil, if current trends continue I wouldn't be surprised to see the storm be classified as fully tropical. It is a big if at this stage however.

Convection has greatly weakened in the vicinity of Subtropical Storm Cari's LLCC overnight, looks like Cari will continue to weaken from hereonin as it slips south into cooler waters.
