Subtropical Storm Alberto

Main Article: Subtropical Storm Alberto

Subtropical storm (SSHWS)
Alberto 2018-05-27 1625Z.jpg
Duration May 25 – May 31
Peak intensity 65 mph (100 km/h) (1-min)  990 mbar (hPa)
Subtropical Storm Alberto was the first Named Storm of the 2018 Atlantic Hurricane Season. Alberto also marked the 4th year in a row that a named storm has been classified before the official start of the season, forming a week before the official start. Alberto formed as a subtropical storm in the northwest Caribbean Sea. Alberto spent many days unorganized, and dumping heavy rains across Cuba and Southern Florida before making landfall around Laguna Beach Florida. It moved inland and weakened to a subtropical depression as it moved over Alabama, eventually transitioning into a fully tropical depression over Tennessee, a rare occurance. The depression remained tropical until it was over Michigan, where it turned post topical, which was very unusual as well.
