Tropical Storm Epsilon is expected to strengthen into a hurricane later this week as it barrels northwest in the Atlantic Ocean.

Epsilon is named for the fifth letter of the Greek alphabet because the 2020 Atlantic hurricane season ran out of names. As of Tuesday afternoon, the storm was packing sustained winds of 50 mph, an increase from earlier in the day. It is located southeast of Bermuda and is moving north-northwest at 8 mph, according to the National Hurricane Center.
