Tropical Storm Joaquin became the 10th named storm of the season after forming late last night (Sept. 28 EDT) in the western Atlantic midway between the Bahamas and Bermuda from what was previously a tropical depression (#11), which itself had formed a day earlier from an area of low pressure that had been lingering in the region since Saturday.
