As I write this, the National Hurricane Center is giving a subtropical cyclone a 30% chance of development in the central Atlantic. Early hurricane seasonal outlooks have been issued and are calling for an "average to slightly below" average Atlantic hurricane season. So it also feels like the time for a little "Hurricane Cone of Uncertainty 101." As we approach the start of the Atlantic hurricane season (June 1st), I often see quite a bit of confusion about the cone of uncertainty that the National Hurricane Center uses with hurricane track forecasts. McNoldy also is adamant about reminding the public and stakeholders that the cone size is fixed for all storms.
