Tropical Storm Erin formed in the eastern Atlantic Ocean on Monday, forecasters said. The storm was expected to strengthen later in the week and could become the Atlantic's first hurricane of the season.

As temperatures continue to heat up this summer, hurricane season is heating up as well. It’s still the first half of the season, but we’re quickly approaching the peak and the Atlantic is starting to look the part.

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.
