Hurricane Bertha (2008) peak as a Category 3 major hurricane with winds of 125 mph (205 km/h) and a minimum barometric pressure of 952 mbar (hPa; 28.12 inHg). The cyclone's rapid intensification phase was equaled by a rapid weakening phase almost immediately after peak intensity, and Bertha fell to minimal hurricane intensity by 06:00 UTC on July 9 under the influence of strong wind shear. These unfavorable winds quickly slackened, allowing Bertha to regain Category 2 intensity by 18:00 UTC that day, before the hurricane began an eyewall replacement cycle. A weak steering regime directed the storm just east of Bermuda as it
Hurricane Bertha (1990) Operationally, forecasters at the National Hurricane Center speculated whether Bertha was transitioning into a subtropical cyclone, due to its deep convection being located, at times, over 200 miles (321.8 km) from the center. However, the convection progressively returned to the center and by late on July 30, Bertha re-intensified into a hurricane as the convection covered the center, about 415 miles (667.8 km) east of where it first formed. Early on July 31, the hurricane briefly attained peak winds of 80 mph (130 km/h) before weakening and accelerated northeastward as the ridge of high pressure was slowly eroded. Bertha maintained
