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.

Tropical Storm Sara formed in the western Caribbean Sea Thursday afternoon as it headed toward Honduras, but there is a great deal of uncertainty about what, if any, impacts the storm will have in Florida or other parts of the U.

A shift in Tropical Depression 19's track has significantly impacted meteorologists' predictions about its potential to form into Hurricane Sara.
