South America

Weather Underground Forecast for Saturday, November 14, 2009.

Tropical storm activity is not expected over the Tropical Atlantic or Caribbean Sea on Saturday. However, the remnants of Tropical Storm Ida will continue moving up the East Coast of the US and will allow for a front to develop to the south. The front will extend over the Bahamas and move southward over Turks and Caicos, and into Haiti and the Dominican Republic. Expect scattered showers to develop along this front, while strongest storms from this system will push into the Mid-Atlantic Ocean.

Meanwhile, high pressure will continue building over Mexico and the Gulf of Mexico. This will bring warm and dry conditions to central Mexico, the Yucatan Peninsula as well as Guatemala, Honduras, and Nicaragua. To the south, onshore flow from the Caribbean Sea will persist over Panama and Costa Rica on Saturday. Thus, expect scattered showers and thunderstorms to persist along the coasts.

In South America, onshore flow over Colombia will trigger another day of scattered storms. Wet conditions will also stretch over Ecuador and into Peru and Bolivia. Further south, a front will regain strength and push northward through northern Argentina and into Uruguay and southern Brazil. Expect heavy showers and thunderstorms over Sao Paulo with highs in the upper 80s(F)/ upper 20s(C). The rest of Argentina will remain dry, while, light rain covers southern Chile. Santiago will be sunny and in the 80s(F)/ upper 20s(C) on Saturday.
