At 9:45 p.m., NHC meteorologists monitoring Tropical Depression Seven analyzed satellite data which indicated the system’s maximum sustained winds increased to 50 mph, Channel 9 meteorologist George Waldenberger said.

The strengthening signified the system’s development from Tropical Depression Seven into Tropical Storm Fiona, the sixth named storm of the season.

The last time the sixth storm formed this late in the season was 2014, according to CSU meteorologist Phil Klotzbach.

It’s too early to be certain that the storm will turn before Florida, Waldenberger said. Early indications show the storm’s curve heading out to sea east of Florida after the system passes Puerto Rico and Hispanola. Channel 9 will continue monitoring the storm as it develops.
