Oct. 4 (Bloomberg) -- Tropical Storm Philippe, churning across open Atlantic waters southeast of Bermuda, is expected to grow into a hurricane tomorrow, according to the U.S. National Hurricane Center said.

Philippe, 665 miles (1,070 kilometers) south-southeast of the islands, is moving west at 12 miles per hour with 65-mph winds, the Miami-based center said in an advisory on its website at 11 a.m.

Philippe is the 16th named storm in the Atlantic hurricane season that runs from June through November. According to the hurricane center’s latest track, Philippe is expected to make a sweeping C-shaped turn to the northeast over the course of this week before heading into the mid-Atlantic east of Bermuda.
