A warning of things to come? Invest 90E could be the earliest tropical depression ever recorded with a 50% chance of developing in the Eastern Pacific Ocean a full three weeks or 21 days before the official season begins on May the 15th.

The earliest tropical depression ever recorded with a 50% chance of developing in the Eastern Pacific Ocean. It is a full three weeks or 21 days before the official season begins on May the 15th. The tropical disturbance called Invest 90E by the National Hurricane Center (NHC) is located about 900 miles south of the southern tip of Mexico's Baja Peninsula.

A First for April

 If the disturbance becomes at least a tropical depression, it would become the first April tropical depression on record in the Eastern Pacific Basin in reliable records since weather satellites began regularly watching the tropics in the late 1960s. The earliest Eastern Pacific tropical depression or storm occurred just three years ago when Tropical Storm Adrian formed off the coast of El Salvador and Guatemala on May 9, 2017. The next May, Tropical Depression One-E formed well southwest of Los Cabos, Mexico, on May 10, 2018. The Eastern Pacific hurricane season generally runs from May 15 to Nov. 30, roughly two weeks before the Atlantic hurricane season according to Weather Underground.
