Tropical Storm Rene was the eighteenth tropical system and the seventeenth named storm of 2020. Slow moving and constantly under attack by wind shear and dry air, Rene never strengthened below 1000 mbar of pressure.
Tropical Storm Kyle was the 12th tropical system and 11th named storm system of the 2020 Atlantic hurricane season. Kyle began as a storm system over eastern North Carolina where officials began keeping an eye on it. Once over the Gulf Stream, the storm gained Tropical characteristics and became a Tropical Storm.
The system struggled against shear from the get-go. While the circulation was closed, most of its center was exposed through vast parts of the storm's life. As quickly as it popped up, it disintegrated.
Peak: 50 MPH, 1000 mbar / hPa.
Hurricane Paulette was the seventeenth tropical system and sixteenth named storm of the hyperactive 2020 Atlantic hurricane season. Paulette is the earliest forming sixteenth storm in recorded history, beating out 2005's Hurricane Philippe by 10 days.
Paulette was tracked as a tropical wave coming off of Africa as early as late August. The wave organized and developed a low pressure system. It became tropical on September 7th. Paulette maintained tropical storm strength, despite strong shear, as it marched its way across the central Atlantic.
As the storm took aim at Bermuda, it began to strengthen. It peaked just after making landfall as a 105 MPH category 2 storm. The next evening, the storm began to weaken due to shear and dry air and quickly became extratropical.
Fast-forward a week later, the remnants of Paulette began to pick up tropical characteristics and redevelop. An interesting note: between the initial development of Paulette and its reformation, seven other storms had developed! It was shorted lived and Paulette became extratropical once again.
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 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 Omar was the fifteenth tropical system and fifteenth named storm of the hyperactive 2020 Atlantic Hurricane Season. The storm that would become Omar became a tropical depression first, being given the numerical identifier 15L. However, the depression didn't strengthen to tropical storm status until after 16L. Thus, 15L received the later 'O' name and 16L received the 'N' name.
Omar affected no land directly while tropical, but did make landfall as an extratropical system over Scotland.
Peak: 40 MPH, 1003 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.
Major Hurricane Delta was the twenty-sixth tropical system and the twenty-fifth named storm of the hyperactive 2020 Atlantic hurricane season. Delta was the earliest forming twenty-fifth storm on record beating Tropical Storm Gamma of 2005 by 42 days. Hurricane Delta is the tenth named tropical system to hit the United States and the third major hurricane.
Delta was unique in that it underwent rapid intensification and had a small ~5 mile-ish eye ..... yet the eye never cleared out during this phase of development. In fact, an eye only presented itself on visible satellite briefly in the Gulf of Mexico.
Delta impacted locations previously hit by other tropical systems. Specifically the Yucatán Peninsula just days after Tropical Storm Gamma and just ~15 miles from where Hurricane Laura made landfall a month earlier in eastern Louisiana.
Peak: 145 MPH, 953 mbar / hPa.
Hurricane Sally was the nineteenth tropical system and the eighteenth named storm of the hyperactive 2020 Atlantic hurricane season. Sally is the earliest forming eighteenth storm on record beating the previous record set by Hurricane Stan in 2005 by 20 days.
Sally began in the Bahamas as an area of disturbance. As it crossed the extreme southern tip of Florida, Sally became a tropical storm. As Sally moved towards the northern Gulf, it quickly strengthened to a category 2 storm. However, slow movement began to limit the amount of warm water under the system as colder water was brought up from the deep (upwelling).
Peak: 105 MPH, 965 mbar / hPa.
Subtropical Storm Alpha was the twenty-fourth tropical system and twenty-second named storm of the hyperactive 2020 Atlantic hurricane season. Alpha is the earliest forming twenty-second storm in recorded history, beating out 2005's Hurricane Wilma by 29 days. Alpha is also the eastern most developing tropical or subtropical storm in the Atlantic basin, beating out 1973's Tropical Storm Christine.
Alpha was also the third confirmed tropical or subtropical system to make landfall on mainland Europe, following an unnamed 1842 hurricane in Spain and 2005's Hurricane Vince. It was the first landfalling tropical or subtropical system in Portugal.
Subtropical Storm Alpha is also notable for heralding in the second time the Atlantic basin ran out of pre-defined names. Per the guidelines of the World Meteorological Organization, the Greek alphabet is used for names going forward.
Subtropical Storm Alpha formed at around 10ºW, an extreme and - as mentioned above - record breaking longitude. The storm gained organization just a short time before making landfall and so officially lasted for three NHC updates (18 hours).
Alpha spawned at least two tornadoes and caused extensive flooding.
