Hurricane Bertha caused minor damage in the United States, Bermuda, and Atlantic Canada in July and August 1990. The third tropical cyclone, second named storm, and first hurricane of the 1990 Atlantic hurricane season, Bertha developed from a frontal low pressure area offshore of North Carolina on July 24. Initially subtropical, it slowly acquired tropical characteristics while tracked southeast and then southwestward. By early on July 27, the cyclone was re-classified as a tropical depression. Following its transition, the depression intensified and was upgraded to Tropical Storm Bertha on July 28. The storm then curved northeastward and 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; 25 to 50 feet (7.6 to 15.2 m) 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. Seven other drowning deaths occurred offshore when the SS Corazon sank near Cape Cod. Minimal impact occurred on Bermuda, limited to mainly tropical storm force wind gusts. In Canada, strong winds caused moderate crop damage in Prince Edward Island and collapsed a suspension bridge in Nova Scotia. Rainfall caused minor flooding in the region. Overall, Bertha caused nine fatalities and approximately $3.91 million (1990 USD) in damage.
