When will the 1st Atlantic storm form..?

[Wpwxguy]

Mid June, around the 20th. Tropical storm in the Bay of Campeche, don't think it'll become a hurricane. Early, I know! Just my thoughts.

The later the better, I want to be here when it gets really active, like early August, but I actually prefer mid to late August, but the first official tropical storm will probably form late June or early July. The first hurricane by late July or early august, I hope.

Typically an Atlantic June storm forms every other year.

Does that math include offsets due to leap years?

Actually, it doesn't included leap years since all but one of the storms over the past 50 years occurred after February, making the leap-day very insignificant. (One did occur in January, but it was a non-leap year.)
