H?urricane season in the Atlantic and Eastern Pacific basins is still in its early stages, but we've already seen multiple oddities that go against the norm.
T?he Atlantic Basin had an unnamed subtropical storm form just a few weeks into the year off the East Coast.
Subtropical storms have characteristics of both tropical storms and the more commonly seen nontropical low-pressure systems. They are usually assigned a number or name, just like a tropical depression or storm.
This subtropical storm wasn't designated in real-time and therefore wasn't named. However, a statement released in May by the National Hurricane Center (NHC) found that it met the requirements for a subtropical storm based on a reanalysis.

T?ropical Storm Arlene briefly made an appearance in the eastern Gulf of Mexico in early June and although it didn't produce notable impacts, it was a meteorological curiosity because of the direction it traveled.
S?torms in the eastern Gulf of Mexico typically track in some sort of north, east or west direction, which means they often landfall along some part of the U.S. Gulf Coast.
A?rlene did the opposite and took a north to south path over the eastern Gulf because of the upper-level steering currents that were in place. It eventually fizzled northwest of Cuba in the face of hostile upper-level winds.

J?une is typically not a very active month for named storms and most that do form are in the Gulf of Mexico or off the East Coast.
That makes Bret's formation location on Monday in the tropical Atlantic between Africa and the Caribbean an outlier since it's just the fourth storm to develop in this region during June since the 19th century, according to NOAA's database. Record warm water and lower wind shear than what's typical this time of year contributed to this Atlantic oddity.
That strangeness could be doubled if a disturbance called Invest 93L in the same region of the Atlantic forms into a tropical depression or storm.
The Eastern Pacific Basin is still waiting for its first named storm more than a month after the season began on May 15.
Only one season since 1970 has had its first named storm develop after June 26 in that basin, according Dr. Phil Klotzbach, a tropical scientist at Colorado State University. That mark could be crossed after next Monday if a disturbance near Mexico doesn't form into a tropical storm before then.
The first named Eastern Pacific storm typically forms by June 10, according to data from the NHC.
A?gatha on July 2, 2016, is the latest date the first storm has developed in the Eastern Pacific.
T?he name Adrian will be given to the season's first storm this year.
