1996: Hurricane Bertha makes landfall near Wrightsville Beach, NC with maximum winds of 105 mph, but the storm surge dealt the most devastation. The U.S. Virgin Islands, along with North Carolina, were declared federal disaster areas. Surveys indicate that Bertha damaged almost 2,500 homes on St. Thomas and St. John.

1969: During the afternoon of Friday, July 4, 1969, thunderstorms formed over southeast Lower Michigan (MI), several of which produced tornadoes, large hail, and high winds west and south of Detroit. As these storms moved southeastward during the early evening, they evolved into a strong derecho over extreme southeastern Michigan (MI) and Lake Erie (LE). The derecho then roared southeast across northern and eastern Ohio (OH) and Western Pennsylvania (PA) during the next few hours. The hourly positions of the gust front (associated with multiple bow echoes) are shown in Figure 1 (above). Winds gusted to 104 mph in Toledo (“T”), and reached 100 mph in the Cleveland (“C”) area. In towns and cities near Lake Erie, many people were outside, preparing to watch Independence Day fireworks. Also for the occasion, many small boat owners had anchored their craft just off the Lake Erie shore to watch the displays. As the derecho passed, untold thousands of trees were blown down, including 5000 in Toledo alone. Along the south side of Lake Erie, eight people were killed by falling trees, and over 100 boats were overturned, drowning at least three persons. A total of eighteen people were killed as a result of the derecho winds in Ohio. Some of the worst damage occurred in Lakewood, a suburb of Cleveland. The storm system continued to uproot trees, damage roofs and produce power outages as it moved into Pennsylvania, where high winds injured five people in Meadville (“M”).
