The wider storm

Tropical Storm Danny formed just east of the Bahamas on August 26, 2009. Danny remained a tropical storm throughout its travels up the east coast of the United States, then turning extratropical as it passed just east of Cape Cod and the islands August 29 and 30. Tropical moisture feeding into the area resulted in heavy rainfall mainly across coastal Massachusetts and Rhode Island which led to minor flooding.

Began near Hyannisport (41.4717, -70.3141).
