South America

Weather Underground Forecast for Saturday, July 19, 2008.

Most of Mexico will remain stormy due to low pressure. Heavy rain and strong thunderstorms are expected in the western and central parts of the country on Saturday. Low pressure will also keep Central America very wet and stormy, and the region can expect very heavy rainfall throughout the day. The tropical wave that will pass through Central America on Friday will move out into the Pacific Ocean off of the southern coast of Mexico on Saturday, where it will have the potential to develop tropical characteristics. A second area of low pressure approaching Honduras and Nicaragua will have the slight chance to develop before it reaches those countries late on Saturday and going into Sunday. Hurricane Elida will continue to move westward away from any land, while Tropical Storms Fausto will strengthen off of the western coast of Mexico, but is not expected to be any threat to land. Meanwhile, the tropical wave moving through the Caribbean will produce showers and storms over the Greater Antilles on Saturday, while the Lesser Antilles will see some showers and strong thunderstorms across the islands.

The northern portion of South America will see seasonable scattered thunderstorms on Saturday. Meanwhile, a weak trough will bring clouds and scattered light rain to a region that extends across Bolivia, northern Argentina, Paraguay, southern Brazil, and Uruguay. The southern tip of the continent will see a few showers due to onshore flow from a high pressure system off of the coast of Chile, while eastern Brazil can expect to see coastal showers.
