East Pacific Basin Hurricane & Tropical Storm Center

Watching Areas South of Mexico for Development

May 23, 2013 11:26 PM

There is an area of thunderstorms several hundred miles south-southwest of the Mexican coast. This area remains disorganized, so any development will be slow to occur. This feature is expected to remain well south of the Mexican coast over the next few days as it heads eastward. Some computer models are indicating low pressure developing just west of Central America late this weekend into early next week and moving south of Mexico. While any tropical development is speculative at this point, this area will be monitored over the next several days. 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.
