a frontal low situated between bermuda and south carolina developed into tropical depression two late on july 6. strong wind shear initially prevented significant strengthening, though by early on july 7, the depression became tropical storm barry. a nearby trough enhanced convection and caused strengthening, with maximum sustained winds reaching 70 mph (110 km/h) later that day. later on july 8, barry weakened slightly, falling to winds of 50 mph (85 km/h), an intensity it would retain until landfall. an approaching mid-level trough accelerated the storm as it traveled roughly along the gulf stream. early on july 9, convection began to shift away from the storm's center. while moving rapidly northeastward, barry made landfall in hart island, nova scotia, late on july 9.
