A powerful tropical storm formed in the Atlantic southeast of Bermuda on Monday, US forecasters said.

Tropical Storm Jerry was situated approximately 1,200 miles (1,935 kilometers) southeast of Bermuda and was expected to take a slow and erratic path east over the next 48 hours.

The storm was packing maximum sustained winds of nearly 40 miles per hour (65 kilometers per hour) with higher gusts.

No coastal watches or warnings were in place, the National Hurricane Center said in an advisory.

This year's hurricane season, which began on June 1, has been quiet compared to previous ones, although the period between August and October often sees the most activity. The season ends on November 30.

Jerry is the 10th tropical storm of 2013, according to the Miami-based National Hurricane Center.
