Tropical Storm Sara now threatens to wreak havoc over Central America with days of heavy rain, flooding and mudslides. Where is it going next?

Tropical Storm Sara formed this afternoon and threatens to bring "life-threatening and potentially catastrophic flash flooding and mudslides" to Honduras throughout the weekend, according to the latest update from the National Hurricane Center. A turn toward Florida is still possible, forecasters said.

In a worst-case scenario for the U.S., a major hurricane could hit Florida's Gulf coast, but forecasters say it would have to clear several hurdles.
