Tropical Storm Aletta formed over the eastern Pacific Wednesday and becomes the first named storm of the 2018 eastern Pacific Ocean hurricane season. Per the climate average from 1971-2009, the first named storm usually forms in the eastern Pacific Ocean basin around June 10th, so it's a little early, but not by much.
Aletta will strengthen over the next few days and is forecast to become a hurricane sometime on Thursday, but it will not be a threat to land.
Another storm that is west of Central America now could form into a tropical system over the next 5 days. If it does develop, it would be named Bud.
In terms of the Atlantic Ocean basin, Alberto has been the only named storm so far this season.
Both Pacific and Atlantic hurricane seasons end on November 30th.
