OK I did some research.
First, Santo Domingo is in the Dominican Republic which is South East of Florida in the Atlantic Ocean.
Kpatch is correct, hurricane season runs from June 1 - November 30th. Living in Florida, every Floridian knows when we have to start stocking up on supplies!
That being said, I went to hurricane.com and checked some stats.
The earliest hurricane on record was:
Earliest hurricane in existence in a calendar year: Hurricane Alice, January 1-6, 80mpg 1955 (and December 31, 1954), formed the previous year.
Ironically, Alice was also the Latest hurricane in existence with it's formation in December.
There was a hurricane on March 6, 1908 as well.
So it *can* happen.
