Quiet in the Eastern Pacific
May 20, 2013 8:10 AM
The area of showers and thunderstorms that used to be Alvin has become completely disorganized due to strong wind shear and will not redevelop into a tropical system. This means that there are no longer any areas of concern for development of tropical systems, for now, over the Eastern Pacific.
In a typical year, the Eastern Pacific basin experiences 15 tropical storms, nine of which are hurricanes, and of those nine hurricanes, four become major hurricanes. Long-term records show that the Mexican and Central American coastal areas in the Eastern Pacific experience two to three landfalls per season.

The Saffir-Simpson Wind Scale is a categorical classification of hurricanes based on their wind speed, used by the U.S. government's National Hurricane Center.
To qualify as a Category 5 hurricane on the Saffir-Simpson hurricane intensity scale, maximum sustained winds must exceed 155 mph (135 kt).
Hurricanes that have a severe impact on lives or the economy are remembered by generations after the devastation they caused, and some go into weather history.
AccuWeather.com has created a number of specialty maps designed for tracking the progress of tropical storms and hurricanes. Use these maps in conjunction with our Hurricane Position graphic, as well as statements issued by the NHC with storm positions.
Hurricanes (by whatever name) are by far most common in the Pacific Ocean, with the western Pacific being most active. In some years, the Philippines are struck by more than 20 tropical storms and typhoons.
