"Historically, tropical systems that reach the western Caribbean in October are more likely to be steered away from places like Texas and Louisiana. But the eastern United States, and Florida in particular, can still be impacted by intense storms," AccuWeather said.

Tropical Storm Melissa formed in the Caribbean Sea on Tuesday as forecasters warned that heavy rain, flooding and strong winds could hit Haiti and Jamaica later this week.

Forecasters at the Hurricane Center said late Tuesday that there was “significant uncertainty” around where Tropical Storm Melissa will go and how intense it will become by the end of this week.
