History has few examples of significant tropical storm early on the calendar

NEW ORLEANS (WVUE) - Subtropical Storm Alberto earned a name on Friday morning, the first storm of a 2018 season that theoretically will begin next week.

Forecasters still expect Alberto to be more of a rainmaker than anything, but officials warned Gulf coast residents to be vigilant over the Memorial Holiday Weekend.

That being said, Alberto's appearance bucks the normal trends through the recorded history of storm tracking dating back to 1851, according to records from the National Oceanic and Atmospheric Administration.

Records show at least one tropical storm has formed in each month on the calendar; only February and April have never tallied an Atlantic hurricane.

A tropical storm occurred in May only about 13 percent of the time, according to NOAA.

Gulf Coast residents concerned about Alberto might find solace in the records, which show no hurricanes have made landfall in the U.S. since at least 1851.

Hurricane season officially begins June 1, but peaks in September

However, June brings an uptick in hurricane activity with 33 hurricanes throughout the period, including 19 that made landfall in the U.S.

The season peaks on September 10.  From 1851-2015, records show 398 hurricanes formed in the Atlantic, the Caribbean, or the Gulf of Mexico, including 107

that eventually struck the U.S.

Records also show, as the saying goes, "it only takes one."  In the relatively inactive year of 1992, Hurricane Andrew did not form until August before marching across Florida as a category 5 and moving onto a second U.S. landfall near New Iberia, Louisiana in late August.

Only 7 tropical storms formed in 1992, but that included Cat 5 Andrew

The 2016 got off to a fast start.  By June 5, Colin had become the third named storm of the season when it made landfall in Florida.   That year produced 7 hurricanes, including 4 major storms.

The least active hurricane season on record remains 1914, which produced only one tropical storm.
