There is a floater for this system?

There is a floater for this system?

I requested a special hazards floater for Subtropical Storm Bapo and the floater is currently still active but the center position isn't updated.

I've contacted SSD to set up another floater for the entire South Atlantic.

Why is this at 40 knots if SSD is 1.0.

[Alyono]

probably satellite data indicates higher winds than the 1.0 indicates

Cari not looking so good at the moment. Convection is always something nice to have as a tropical or subtropical cyclone, but that's not something Cari has right now...
