Threats From Ernesto Impacting US Coastal Areas

Tropical Storm Adrian was a record-early eastern Pacific named storm that formed on May 9, 2017, well off the coast of Central America.

Adrian was the earliest tropical cyclone to form in the northeast Pacific in the satellite era. This record was previously held by Hurricane Alma in 1990.

However, strong wind shear took its toll on the tropical cyclone and Adrian weakened to a tropical depression 24 hours later on May 10.

Adrian's main thunderstorm activity had become well removed from its center of circulation by early May 11, and the National Hurricane Center said it had degenerated to a remnant low.

The lion's share of thunderstorm activity at that time was occurring far from the center along the coasts of southeast Mexico, Guatemala and El Salvador.

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.
