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.

Sara will bring stormy weather to Florida followed by the state's first taste of winter after a summery autumn.

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