A low pressure area formed along a frontal zone in the western Atlantic on 12 August 2011, about 150–200 nautical miles north‑northwest of Bermuda. The system became a compact tropical depression at 1800 UTC 12 August, moved northeastward, and strengthened into Tropical Storm Franklin around 0600 UTC 13 August while about 450 n mi south‑southeast of Halifax, Nova Scotia. Franklin reached its peak intensity later that day and then transitioned into an extratropical cyclone by 1800 UTC 13 August. The remnant low moved eastward and southeastward and degenerated into a trough by 0600 UTC 16 August about 500 nmi west‑southwest of the Azores.
Franklin did not make landfall. Its entire life cycle was over the open Atlantic, and it did not affect Bermuda, Canada, or other land areas.
The storm’s maximum sustained winds peaked at 40 knots (46 mph) at 1200 UTC 13 August, with a minimum central pressure of 1004 mb. At peak it was a tropical storm and was classified as extratropical later that same day.
There were no reports of storm surge or rainfall impacts associated with Franklin on land. No ship reports of tropical‑storm‑force winds were recorded while Franklin was a tropical cyclone.
No deaths or damage were reported in connection with Franklin.
The storm’s development was not well anticipated: the disturbance was first given a 10% chance of development 48 hours before genesis and only 30% six hours before formation. Because Franklin was short‑lived and stayed over open water, there are limited track and intensity verification statistics.
