Subtropical Storm Alberto is yet another storm that has formed before the official start of the Atlantic hurricane season, which is June 1st. Alberto formed on May 25th. Five out of the seven years have featured the formation of the tropical or subtropical cyclone before the start of the hurricane season. According to Professor Brian McNoldy of the University of Miami, “over the past 30 years (1988-2017), the trend in date of first Atlantic named storm is clear. ” That is the fact that the first named storm has been happening earlier on average as time progresses.

Here’s a few of the records Alberto may break, some of which are by Phillip Klotzbach:
- Alberto is a subtropical storm at 19.3°N – only 1 subtropical storm on record in the Atlantic has been further south (Olga in December, 2007).
- The earliest calendar year continental US hurricane landfall on record (since 1851) was Hurricane Alma in 1966 on June 9. It made landfall in Florida as a Category 2 hurricane. Alberto has the low chance at becoming a hurricane, which would break this record.
- There has never been a hurricane that has affected the Gulf of Mexico during the month of May in recorded history. The strongest storm in the Gulf of Mexico in May was Alice in 1953. Winds reached 60 knots (70 mph).
- Alberto’s central pressure of 991 mb, as of Sunday night, is the lowest for an Atlantic named storm during May since Subtropical Storm Alpha in 1972.
