Apolo, Bolivia

Weather Underground Forecast for Saturday, May 25, 2013.

In the Eastern Pacific Basin, an area of low pressure has a medium chance of tropical cyclone development by Saturday. The system remains about 550 miles south-southwest of Acapulco, Mexico and remains slightly organized. Conditions may become favorable for development, thus, this system has a 30% chance of strengthening. If this system develops, it will take a northwestward track and remain well offshore of western Mexico. Meanwhile in the Atlantic Basin, tropical cyclone activity is not anticipated on Saturday. However, areas of active weather will persist for the Caribbean Sea and Latin America. In the north, the tail end of a cold front lingers over the Bahamas and moves into the Turks and Caicos throughout the day, bringing a few scattered showers and thunderstorms to the region. In the west, an area of low pressure over the western Caribbean Sea pushes moisture onshore into Central America, bringing widespread showers and thunderstorms to the region from Panama through Guatemala and southern Mexico. Some of these storms will create strong winds and heavy rainfall.

In South America, a tropical wave of low pressure from the Mid-Atlantic Ocean approaches the northeastern countries on Saturday. This will push moisture onshore, increasing chances of storms from Amapa through eastern Venezuela. Meanwhile in the west, onshore flow from the Pacific Ocean will maintain moderate to heavy showers and thunderstorms across Colombia and into Ecuador and Peru. To the south, high pressure builds from Argentina through eastern Brazil, bringing dry and sunny conditions to these areas. Further south, however, a strong storm moves into southern Chile, bringing heavy precipitation to the southern tip of the continent.
