Hurricane Dennis was a disorganized Category 1 hurricane that caused severe flooding in Miami-Dade County, Florida, as a tropical storm in August 1981. The tenth tropical cyclone and fourth named storm of the season, Dennis developed from a tropical wave well south of Cabo Verde on August 7. The depression intensified into a tropical storm early the next day. Dennis then encountered strong wind shear, causing the storm to weaken to a tropical depression on August 11. After crossing the Windward Islands on August 12, Dennis degenerated into a tropical wave several hours later over the Caribbean Sea. The wave became a tropical depression again late on August 15 while approaching Cuba. Dennis reintensified into a tropical storm before landfall in Matanzas Province. The cyclone emerged into the Straits of Florida on August 16, before striking the Florida Keys and then mainland Monroe County early the next day. It drifted across Florida, reaching the Atlantic near Cape Canaveral on August 19. Dennis continued to intensify and made landfall near Emerald Isle, North Carolina, but moved east-northeastward and soon tracked offshore. Late on August 20, Dennis deepened into a hurricane with winds of 80 mph (130 km/h), before weakening to a tropical storm over colder waters on August 21. Dennis became extratropical northeast of Bermuda early on August 22 and persisted until being absorbed by a frontal system on August 26. Category 1 hurricane: peak winds of 80 mph (70 knots), lowest pressure 995 mb. August 7 – August 22, 1981. Accumulated cyclone energy: 6.4.
