Tropical Storm Erin formed on Monday, with AccuWeather predicting it may strengthen into a major hurricane later this week.

Meteorologist Devon Lucie has the latest on Erin and where the storm is likeliest to track, and if there's any chance of moving into the Caribbean or the Gulf, then shows you a weak system highlighted by the National Hurricane Center in the Gulf that is surging in higher tropical humidity and responsible for a lot of storms over the South Shore and what to expect for storm activity through midweek.

Tropical Storm Erin formed on Monday in the far eastern Atlantic and is forecast to reach major hurricane strength by this weekend, the National Hurricane Center said.
