Major Hurricane Laura was the thirteenth tropical system and twelfth named storm of the 2020 Atlantic hurricane season. Laura was the earliest forming twelfth storm in recorded history. When the storm became a tropical depression, it did so around the same time as another tropical depression formed (later Hurricane Marco). At one point, both storms were predicted to make simultaneous landfalls on the US Gulf states as category 1 hurricanes. Laura remained under hurricane strength until reaching the Gulf of Mexico. Upon entering those water, rapid intensification quickly created a category 4 monster of a storm.
Laura made landfall near Cameron, Louisiana, just 1 mbar / hPa above its peak lowest pressure and tied the 1856 Last Island Hurricane as the strongest (deepest low pressure) to hit the US state of Louisiana.
As of August 31st, Major Hurricane Laura is estimated to have caused US$8 billion in damages.
Tropical Storm Arthur was the first cyclonic storm of the 2020 Atlantic Hurricane season. Arthur developed before the official June 1st start of the season and makes this the sixth year in a row that a named storm has developed before June 1st.
Peak: 65 MPH, 989 mbar / hPa.
Tropical Storm Josephine was the 11th tropical system and 10th named storm of the so-far 2020 Atlantic season. Josephine became the earliest 10th storm beating 2005's Jose by 9 days.
Josephine struggled with wind shear and dry air over most of it's existence.
Peak: 45 MPH, 1004 mbar / hPa.
Tropical Storm Gonzalo was the earliest seventh named system in an Atlantic hurricane season, beating the previous record-holder Tropical Storm Gert of the 2005 season by three days.
Peak: 65 MPH, 997 mbar / hPa.
Tropical Storm Beta was the twenty-second tropical system and twenty-third named storm of the hyperactive 2020 Atlantic hurricane season. The reason the storm was the 22nd overall but 23rd named is because Beta formed as Tropical Depression Twenty-Two between the systems that would become Vicky and Wilfred, but did not reach tropical storm status and thus receive a name until Wilfred and Alpha became named storms. Beta is the earliest forming twenty-third storm in recorded history, beating out 2005's Tropical Storm Alpha by 34 days.
Tropical Storm Beta was a slow moving meandering storms that spent a lot of time just floating around in the Gulf. Even before tropical development, the storms and low pressure swirl that eventually became Beta had been moving about the Gulf for days.
Slow moving, Beta dropped rain for days over the Gulf Coast regions.
Peak: 60 MPH, 994 mbar / hPa.
Tropical Storm Gamma was the twenty-fifth tropical system and twenty-fourth named storm of the hyperactive 2020 Atlantic hurricane season. Gamma is the earliest forming twenty-fourth storm in recorded history, beating out 2005's Hurricane Beta by 24 days.
The National Hurricane Center began watching a broad area of disturbed weather near the Lesser Antilles at the end of September. In early October, the system was able to consolidate and strengthen into a tropical storm. Gamma was near hurricane strength when it made landfall near Tulum, Mexico, on October 3rd. Although initially predicted to survive in the Gulf, shear and dry air quickly doomed Gamma.
Peak: 70 MPH, 980 mbar / hPa
Hurricane Zeta was the twenty-eighth tropical system and the twenty-seventh named storm of the hyperactive 2020 Atlantic hurricane season. Zeta was the earliest forming twenty-seventh storm on record beating Tropical Storm Epsilon of 2005 by 35 days.
The western Caribbean was flagged as a spot of concern for development well before a low pressure system actually formed. Zeta formed slowly and meandered for awhile. As it got closer to the Yucatán it began to pick up strength.
After crossing the Yucatán, Zeta's forward speed increased quickly and barely spent 18-hours over the United States.
Tropical Storm Wilfred was the twenty-third tropical system and twenty-first named storm of the hyperactive 2020 Atlantic hurricane season. Wilfred is the earliest forming twenty-first named storm in recorded history, beating out 2005's Hurricane Vince by 20 days.
Tropical Storm Wilfred was monitored as it came off of Africa. Although the potential for cyclogenesis had been there for a while, wind shear prevented development. Wilfred was eventually able to persevere for a few days and attain tropical characteristics. However, the wind shear proved to be too great and can be see ripping the storm apart towards the tail end of the sequence.
Peak: 40 MPH, 1007 mbar / hPa.
Tropical Storm Dolly was the fourth named storm of the 2020 Atlantic hurricane season. Initially subtropical, Dolly briefly held tropical status for nearly 24-hours while the center of circulation was over the Gulf Stream. Upon leaving the stream, the storm weakened and its center was left exposed.
Peak: 45 MPH, 1002 mbar / hPa
Tropical Storm Edouard was the fifth named storm of the 2020 Atlantic hurricane season and the earliest fifth since reliable records began. Another short-lived system, Edouard maintained tropical storm status for less than 24 hours.
Peak: 45 MPH, 1005 mbar / hPa
