Etta may have been blowing at speeds of up to 35 mph, but the prolonged tropical depression is still predicting more than 3 feet of rain.
An additional 30 inches of rain is still possible in Honduras, Guatemala and Belize, and a further 20 inches can be seen in parts of El Salvador, Nicaragua, Costa Rica and southeastern Mexico.
The storm quickly weakened and subsided into a tropical depression by Wednesday evening. According to CNN meteorologist Derek von Dam, it is expected to recede further until Thursday night as its remains travel into the Gulf of Honduras and into the Caribbean Sea.
The National Hurricane Center says Etta will intensify into a tropical storm again before it is forecast to make landfall in western Cuba on Saturday night and then into the Florida Strait by Sunday afternoon.
There is still a lot of uncertainty about the strength of Etta to reach the U.S. coast, but it is likely to continue to bring heavy rains, life-threatening flash floods, river flooding and landslides, Van Dam said.
