South America

Weather Underground Forecast for Wednesday, August 27, 2008.

Tropical Depression Fay is expected to weaken as it moves to the northeast on Wednesday. While the storm will continue to bring showers and isolated thunderstorms, the intensity of these storms are also expected to weaken as the storm progresses.

Meanwhile, atmospheric and oceanic conditions will be favorable for strengthening Tropical Storm Gustav into a Category 1 hurricane on Wednesday. The storm's movement will continue toward the northwest and is expected to make landfall with southeastern Cuba Wednesday afternoon. The storm is expected to bring heavy rainfall, high winds and thunderstorms as it treks through the country. Interaction with land should weaken Gustav to a Tropical storm.

There is also an area of disorganized cloud coverage and showers associated with a tropical wave located several hundred miles northeast of the Leeward Islands. The area will remain under watch, although upper level winds are not favorable for tropical cyclone development.

Elsewhere, seasonal scattered showers are expected to persist throughout Central America. Temperatures are expected to remain hot.

In South America, scattered showers are expected in the northern coastal countries, with the largest amounts of rainfall occurring in Venezuela. To the south, a front passing through central Argentina will cause areas of the country to see significant amounts of showers. Southern Chile will continue to see a mixture of snow, sleet and rain on Wednesday.
