South America

Weather Underground Forecast for Thursday, August 21, 2008.

Tropical Storm Fay is is expected to begin trekking westward after moving over water just off the east coast of Florida. The change in direction will be due to a developing ridge that will cause the storm to move northwest toward northern Florida or the Georgia coast. There is a possibility that the storm may regain strength and intensify before returning to land early Thursday morning. The system will continue to be closely monitored as it progresses.

Another low pressure system about 950 miles southwest of the Cape Verde Islands will continue moving northwestward in the North Atlantic. Although environmental conditions are only slightly favorable for tropical development, the possibility of slow development will keep the system under close observation on Thursday.

Meanwhile, hot temperatures and scattered seasonal showers are expected to persist in Central America. A tropical wave moving toward Honduras and Nicaragua will bring showers to these regions.

In South America, scattered showers are expected to persist in the northeastern countries. Eastern Venezuela will continue to see the heaviest of these showers on Thursday. To the south, a band of showers are expected to extend from Peru into southeastern Brazil. High pressure moving through Argentina will keep rainfall to the north of this country. Meanwhile, southern Chile will continue to see the rain and snowfall.
