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

The National Hurricane Center began advisories Wednesday on a system it forecasts to become the season’s next tropical depression or storm. Long-range forecast models predict it will intensify into a hurricane and threaten Florida by the middle of next week.

Forecasters tell residents of eastern Gulf Coast and Florida to monitor the forecast closely for potential impacts next week.
