Hurricane Dolly (2020-Sandy156)

Hurricane Dolly was a Category 2 hurricane that produced minor flooding in Cuba in July 2020 due to its slow movement. Dolly was the fourth named storm and third hurricane of the annual hurricane season.

Meteorological history
In early July, a tropical wave emerged off the coast of Africa. For several days, it advanced westward for several days, no change in organization. 2 days after it entered the Caribbean Sea, the NHC tracked it, giving it a low chance of forming. It drifted slowly in the Caribbean, very gradually organizing. Finally on July 14 at 12:00 UTC, it developed into Tropical Depression Four. Due to increasing wind shear, the system struggled to strengthen for a few days, trying to maintain being a tropical depression. On July 17, the wind shear started to subside, the system now able to intensify. The next day at 00:00 UTC, the depression finally became a tropical storm, named Dolly. It turned northwest, gradually intensifying as the wind shear completely impacted the storm no more. It then strengthened more rapidly and on July 19, 12:00 UTC, it became a hurricane. The hurricane now turned north-northeast right toward Cuba after it was upgraded to a hurricane. It became a Category 2 hurricane on July 20, 06:00 UTC, and reached its peak intensity 12 hours later right before landfall. It had maximum winds of 100 mph (155 km/h) and a minimum pressure of 984 mbar (hPa) at the time of its peak.

12 hours later, on July 21, 06:00 UTC, Dolly made landfall in the southern province of Ciego de Ávila. Intensity decreased slightly between its peak intensity and landfall, with 5 mph (10 km/h) decrease in wind speed and 3 mbar (hPa) increase in pressure. However, it remained a Category 2 until it exited Cuba, on July 21 at 15:00 UTC, where it weakened back to a Category 1. For the period of July 21 at 18:00 UTC to the next day at 18:00 UTC, it then impacted the Bahamas, falling below hurricane strength on July 22 at 12:00 UTC. Once it exited the Bahamas, however, it continued to abate, weakening to a tropical depression on July 23 at 18:00 UTC. 12 hours later, it became a tropical storm again, while gradually intensifying abruptly. It strengthened into a hurricane on July 25 at 18:00 UTC and then reached its secondary peak intensity 6 hours later, with winds up to 80 mph (130 km/h) and a minimum pressure of 989 mbar. After that, due to increasing wind shear, it started to diminish. It weakened back to a tropical storm on July 26, 06:00 UTC, and then to a tropical depression again on July 27, 00:00 UTC. It eventually became a remnant low at 18:00 UTC that day, which dissipated the next day.
