South America

Weather Underground Forecast for Sunday, November 08, 2009.

Active tropical storm activity will persist over the Caribbean Sea on Sunday as multiple weather features hover over the region. Tropical storm Ida has lost some of its strength due to its northward track over Honduras and Nicaragua. However, the system will jump back into the warm waters of the Caribbean as it continues moving up the Yucatan Peninsula. Counter-clockwise flow around this system will continue picking up ample moisture from the Caribbean and Gulf of Mexico, which will trigger heavy showers and thunderstorms along the surrounding coasts. Expect wet weather from Ida to stretch from Nicaragua to eastern Mexico. Additionally, another area of low pressure hovering south of Mexico will continue picking up moisture from the Pacific Ocean, and will spread scattered showers over southern Mexico and Guatemala.

In the east, a lingering frontal boundary will extend over the Great Antilles. This will bring another day of scattered showers and thunderstorms over the Lesser Antilles, with heavier showers and thunderstorms developing over Cuba.

Meanwhile in South America, usual wet weather will persist over the northern countries, while onshore flow over Colombia will kick up heavy showers and thunderstorms. To the south, an intense frontal boundary will stretch from the Atlantic coast in southern Brazil and into Bolivia. This system will trigger moderate to heavy storms throughout the day, with scattered showers extending into central Brazil. Sao Paulo will remain rainy with highs in the upper 70s(F)/ mid-20s(C). Chile and Argentina will remain under mild weather conditions as higher pressure dominates the weather. Thus, expect mostly sunny skies in Santiago with highs in the lower 70s(F)/ lower 20s(C).
