The NHC predicts “some strengthening is forecast during the next day or so”.
Tropical Storm Eta is “forecast to become a hurricane” as it tracks near or over the Florida Keys on Sunday night and early Monday.
Commenting on the storm’s progression, the Accuweather website states: “Forecasters say that as the storm continues to move away from Cuba and conditions become more conducive for strengthening, Eta could reach Category 1 hurricane strength (maximum sustained winds of 74-95 mph) just prior to or after a projected landfall in the Florida Keys Sunday night.
“Regardless of exact intensity, South Florida will endure heavy rainfall, strong winds, storm surge flooding and isolated tornadoes.”
