Andres has become the earliest named storm on record to form in the Eastern Pacific.The storm is no threat to land and should be short-lived.

Tropical Storm Andres formed in the Eastern Pacific Ocean on May 9, 2021, becoming the earliest named storm on record to develop in that basin.

Andres' formation at 9 a.m. MDT on Sunday marked the earliest in the satellite era, or since the mid-1960s, that a named storm has developed in the Eastern Pacific Ocean.

The previous record was set by Tropical Storm Adrian, which formed 12 hours later in the calendar in May 2017.

Andres quickly succumbed to strong wind shear, drier air and a more stable environment over 500 miles south of the southern tip of Baja California and never was a threat to land.

The eastern Pacific season begins May 15, which is about a half-month earlier than the Atlantic season. The earlier start date is due to warmer waters and typically weaker wind shear earlier in the season as compared to the Atlantic.

Blanca will be the name given to the next Eastern Pacific storm that forms this season.
