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.

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

Tropical Storm Sara has formed in the Caribbean and is expected to bring life-threatening rainfall, flooding, and the potential for mudslides to parts of Central America, the National Hurricane Center said.
