Sunday marks the official start of the 2011 hurricane season in the Eastern Pacific, a season which is expected to exceed the amount of named tropical systems from last year by twofold.

AccuWeather.com meteorologists are predicting an average number of tropical systems to develop in the Eastern Pacific this year.

The basin averages 15 tropical storms each season. Out of those, nine become hurricanes, with four reaching major hurricane status.

Fifteen named storms would more than double the total from last year. Only seven named storms formed in the Eastern Pacific in 2010, with three reaching hurricane status.

"Last year was... about as quiet as it can get," stated AccuWeather.com Western Expert Meteorologist Ken Clark.

"A strengthening La Ni storms [last year]," reported AccuWeather.com Staff Writer Gina Cherundolo in her recap of the 2010 Eastern Pacific hurricane season.

A weakening La Ni back to normal this year.

"The water [in the Eastern Pacific] will steadily warm, which will lead to lower pressure," stated AccuWeather.com Expert Senior Meteorologist Bob Smerbeck. Lower pressure will then open the door for the development of tropical systems.

"Since the pressure will remain slightly above average early in the season, we are not expecting a quick start," Smerbeck added.

There are clusters of thunderstorms currently streaming across the Eastern Pacific, but none show signs of future development.

The first tropical storm to develop in the Eastern Pacific this year will acquire the name "Adrian." Story by Kristina Pydynowski, AccuWeather.com Senior Meteorologist
