2019 Hurricane Season in Review

No Retired Hurricanes for 2019
Due to Covid-19 Pandemic

Due to the Coronavirus pandemic, the annual week-long meeting of the World Meteorological Organization (WMO’s) hurricane committee was canceled.

Storm names are retired if they were so deadly or destructive that the future use of the name would be insensitive - otherwise names are reused by NOAA’s National Hurricane Center on a six-year cycle.

Replacement names, to be used in 2025, would have been announced. We will have to wait another year to find out what storms from the 2019 season will be retired.

There are some likely candidates for retirement when the WMO committee meets in 2021.  Hurricane Dorian, which made landfall in the Bahamas as a Category 5 hurricane, tops the list of possibilities.   It devastated the Bahamas, brought tropical storm conditions to the east coast of Florida, and impacted cruises resulting in one of the largest industry relief responses in its aftermath.

Tropical Storm Imelda never reached hurricane status but nonetheless it left its mark on Texas.  This slow moving storm dumped more than 40 inches of rain in East Texas.

Hurricane Lorenzo, another Category 5 storm, will be remembered as the easternmost Category 5 storm on record in the Atlantic.




The 2019 Atlantic hurricane season was the fourth consecutive year of above-average and damaging seasons dating back to 2016. It is tied with 1969 as the fourth-most active Atlantic hurricane season on record in terms of named storms.

Looking Back at 2019

The Atlantic season produced 18 named storms, including six hurricanes of which three were “major” (Category 3, 4 or 5). NOAA’s outlook called for 10-17 named storms, 5-9 hurricanes and 2-4 major hurricanes, and accurately predicted the overall activity of the season.

The only other period on record that produced four consecutive above-normal seasons was 1998-2001. Also this year, five tropical cyclones formed in the Gulf of Mexico, which ties a record with 2003 and 1957 for the most storms to form in that region. Of those, three — Barry, Imelda and Nestor — made landfall in the U.S.

The 2019 Pacific hurricane season was a near average season which produced nineteen named storms, though most were rather weak and short-lived. Only seven hurricanes formed, the fewest since 2010. The season had a rather slow start, with no tropical cyclones forming in the basin during the month of May for the first time since 2016, and the first time that no storms formed before the month of June since 2011.

Measuring total seasonal activity: The Accumulated Cyclone Energy (ACE) index

An important measure of the total overall seasonal activity is the NOAA Accumulated Cyclone Energy (ACE) index, which accounts for the intensity and duration of named storms and hurricanes during the season.  According to NOAA’s hurricane season classifications, an ACE value above 117% of the 1950-2000 median reflects an above-normal season. An ACE value above 175% of the median reflects an exceptionally active (or hyperactive) season.

Hurricane Season Dates 

Hurricane season in the Atlantic begins June 1st and ends November 30th. The Eastern Pacific hurricane season begins May 15th and also ends November 30th.

2017 Hurricane Season in Review

Four 2017 Hurricane Names Retired
Harvey, Irma, Maria, and Nate

3 Simultaneous Hurricanes - Katia, Irma, Jose (NOAA)
Due to the extensive damage caused in the United States and Caribbean last year, the World Meteorological Organization’s Region IV Hurricane Committee has officially retired these names. Storm names are retired if they were so deadly or destructive that the future use of the name would be insensitive - otherwise names are reused by NOAA’s National Hurricane Center on a six-year cycle. Replacement names, to be used in 2023, have also been announced.  Read more


Here's the reasoning behind the decision and what the new names will be.



The extremely active 2017 Atlantic hurricane season was one of the most destructive on record. Damage costs exceeded 250 billion dollars in the United States alone, while recovery for the worst hit Caribbean islands such as Dominica may take years. Several hundred people died, and the lives of millions were impacted.

Looking Back at 2017

The 2017 Atlantic hurricane season was a hyperactive and catastrophic hurricane season, featuring 17 named storms, 10 hurricanes and 6 major hurricanes – ranking it alongside 1936 as the fifth-most active season since records began in 1851. The season also featured both the highest total accumulated cyclone energy (ACE) and the highest number of major hurricanes since 2005.

In the chart below, the numbers in parenthesis are the averages, so you can easily see that the 2017 Atlantic Hurricane Season was well above average.  Read more (comprehensive coverage)

The 2017 Pacific hurricane season was a moderately active Pacific hurricane season, featuring eighteen named storms, nine hurricanes, and four major hurricanes, though the season was significantly less active than the previous three seasons. The season saw near-average activity in terms of ACE, in stark contrast to the extremely active seasons in 2014, 2015, and 2016; and for the first time since 2012, no tropical cyclones formed in the Central Pacific basin. However, for the third year in a row, the season featured above-average activity in July, with the ACE value being the fifth highest for the month.
