the depression was upgraded to Tropical Storm Arlene late on July 5; in the post-season summary, meteorologist Neil Frank noted, "the surprising element in the development of Arlene was the rapidity of the transformation process." Upon being named, Arlene continued northeastward, possessing a circular mass of convection with spiral rainbands. Late on July 6, the storm attained peak winds of 65 mph (100 km/h), based on a ship report. It weakened thereafter, and Arlene transitioned into an extratropical cyclone late on July 7 just south of Newfoundland. The cyclone last observed early the following day. The storm capsized a boat in the Grand Banks of Newfoundland, and the crew of 12 was rescued. Hurricane Two A hybrid-type depression formed east of Bermuda on July 29. It moved rapidly southwestward before turning to a northwest drift. On August 3, it was classified as a tropical depression, and the next day the system passed near Bermuda. The depression accelerated to the northeast, strengthening into a tropical storm on August 5. It intensified further due to baroclinity, or enhanced instability through different levels of the atmosphere caused by temperature and moisture gradients. On August 6, a drilling rig about southeast of Newfoundland recorded sustained winds of with gusts to 126 mph (204 km/h) at an altitude of ; this suggested the storm attained hurricane status at 46° North, which is the northernmost location for a tropical storm to intensify into a hurricane. Despite the intensity, the cyclone was not purely tropical; although the radius of maximum winds was only , the thermal structure did not resemble a tropical cyclone, and there was no precipitation or convection near the center. It continued northeastward and dissipated on August 7 to the southwest of Greenland. It was not named operationally, but it was later added to the Atlantic hurricane database. Hurricane Beth On August 9, an upper-level low developed off the coast of Florida, and the next day spawned a tropical depression. The newly developed cyclone tracked slowly northeastward, eventually encountering conditions favorable for development. On August 14, the depression intensified into Tropical Storm Beth off the coast of North Carolina, and it quickly strengthened into a hurricane by August 15. After reaching peak winds of off the coast of Cape Cod, Beth slightly weakened and later moved ashore near Copper Lake, Nova Scotia. Shortly thereafter, Beth was swept up by a nearby cold front and
