The official start of the eastern Pacific hurricane season is May 15, but tropical development is starting a little earlier this year.
A large area of showers and thunderstorms off the coast of Central America has developed into the first tropical storm of the year in the eastern Pacific.
Tropical storm Adrian is likely to develop into a hurricane before making landfall along the Mexican coast on Monday.
The storm rapidly strengthened on Tuesday, becoming the earliest tropical depression and tropical storm on record in the eastern Pacific Ocean since reliable data began in 1966.
The previous record for the earliest tropical depression was on May 12, 1990.
This depression strengthened to Tropical Storm Alma on May 14.
“With water temperatures off western Central America above normal and relatively low wind shear, conditions will be conducive for strengthening,” AccuWeather Meteorologist Steve Travis said.
