Hurricane Bertha (1990) rapidly strengthened. Bertha became a hurricane early on July 29, though it weakened back to a tropical storm later that day. On the following day, Bertha re-intensified into a hurricane and peaked as an 80 mph (130 km/h) Category 1 hurricane on July 31. Early on August 2, Bertha made landfall near Sydney, Nova Scotia while weakening and transitioning back into an extratropical cyclone. Large waves impacted the East Coast of the United States; waves were reported along the coast of North Carolina. In Florida, rough seas caused two fatalities by drowning, as well as at least 200 lifeguard rescues.
Hurricane Bertha (2008) 77 °F (25 °C), and its overall appearance was characterized by intermittent bursts of deep convection near the center. Eventually, by late on July 5, Bertha began to enter warmer waters and gain organization. Convection coalesced throughout July 6, and a series of microwave passes later that day indicated the formation of an eye-like feature, despite some tilt to Bertha's low- and mid-level circulations. Rapid deepening ensued as the aforementioned eye became readily apparent and convection in the eyewall cooled; Bertha became the season's first hurricane around 06:00 UTC on July 7, and by 21:00 UTC that afternoon, attained its
