Hurricane Hanna (2020-Sandy156)

Hurricane Hanna was a minimal hurricane that struck Florida and Newfoundland in August 2020, causing minimal damages there.

Meteorological history
A tropical low formed on August 6, in the Caribbean Sea. It headed northwest, slammed into the Yucatan Peninsula, and then entered the Gulf of Mexico a few days later. It turned right toward the state of Florida and then started to organize. On August 12 at 12:00 UTC, it was designated as Tropical Depression Nine. Then on August 13 at 12:00 UTC, it intensified into Tropical Storm Hanna, about 1,000 mi (1,600 km) west of Florida. It reached its initial peak intensity 6 hours later, with winds of 45 mph (70 km/h) and a minimum pressure of 998 mbar. It struck Florida at its initial peak intensity at 21:00 UTC that day, its landfall diminishing the storm into a tropical depression on August 14 at 00:00 UTC and then a remnant low at 12:00 that same day.

The remnant low drifted for several days, with no change in organization due to dry weather and wind shear. Finally, late on August 18, it was better organized due to improved conditions and was redeveloped into a subtropical depression. On August 20, 00:00 UTC it intensified into a subtropical storm, while it was on the verge to becoming fully tropical. Eventually, at 18:00 UTC that day, it fully transitioned into a tropical storm, turning toward the northeast. On August 22 at 00:00 UTC, it strengthened into a hurricane, despite the cooler waters there. Six hours later, it reached its peak intensity, with maximum winds of 80 mph (130 km/h) and a minimum pressure of 989 mbar (hPa). Decreasing water temperature weakened the system, becoming a tropical storm again at 18:00 UTC that day. Early on August 23, it struck Newfoundland with winds up to 60 mph (95 km/h) and a minimum pressure of 994 mbar (hPa). 6 hours later, it transitioned into a extratropical cyclone, still over the island.
