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.
