Tropical Storm Chantal formed Tuesday morning in the Atlantic Ocean between Bermuda and Massachusetts, but it was not expected to threaten the United States, forecasters said.
At 8:15 a.m. EDT, the third named storm of the Atlantic hurricane season had maximum sustained winds of 40 mph and was centered about 330 miles south of Halifax, Nova Scotia, according to the National Hurricane Center. It was moving northeast at about 23 mph.
The threshold for a tropical storm is sustained winds of 39 mph. When those winds reach 74 mph, it becomes a hurricane. But Chantal was expected to be a short-lived tropical storm that would likely weaken, forecasters said.
"Chantal is not a threat to the United States," hurricane specialist Eric Blake said. The storm could affect Newfoundland late Wednesday or early Thursday, but it will not be too strong, he said.
There have been two other named storms in 2007: Subtropical Storm Andrea, which formed in May, and Tropical Storm Barry, which formed June 1, the first day of hurricane season.
