A storm system, which would earn the name “Sara,” is expected to form soon in the Caribbean, and could affect the United States down the road. It’s too early to know exactly where the storm will go once it forms and what areas will be affected — particularly because the system has no established center of circulation yet.

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

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.
