Tropical Storm Hermine was a short-lived tropical cyclone that formed in the far eastern tropical Atlantic Ocean and brought record-breaking rains to the Canary Islands in September 2022. Hermine originated from a tropical wave first noted over West Africa on September 20. After emerging over the far eastern Atlantic Ocean, the system organized into a tropical depression on September 23. It soon became the eighth tropical storm of the 2022 Atlantic hurricane season as it progressed north. Increasing wind shear created a hostile environment for the cyclone and it failed to intensify beyond minimal tropical storm intensity as its convection was stripped far to the northeast. By September 24, Hermine's structure had sufficiently degraded to mark its degeneration into a remnant low. The residual system persisted for another two days before it was last noted over open ocean.

Hermine brought historic rainfall to the western Canary Islands over a three-day span. Accumulations reached {{convert|20.87|in|mm|abbr=on|order=flip}} in La Palma, more than 20 times the normal rainfall for the month of September. Many areas reported more than {{convert|100|mm|in|abbr=on}} of rain throughout the event. The tremendous rainfall significantly disrupted air travel and damaged roads across the archipelago. Many structures suffered from flooding and total damage exceeded 10 million euro (US$9.8 million). Approximately 3,000 customers lost electricity, with service restoration taking up to five days in some locales. However, residents reported outages lasting longer than stated with one community remaining dark as of October 4. Repairs to roadways were expected to take at least five months.

Meteorological history

On September 20, 2022, the National Hurricane Center (NHC) began monitoring a tropical wave over West Africa for possible tropical cyclogenesis.{{cite report|first=Lisa|last=Bucci|publisher=National Hurricane Center|date=September 20, 2022|accessdate=October 4, 2022|title=Five-Day Graphical Tropical Weather Outlook|url=https://www.nhc.noaa.gov/archive/xgtwo/gtwo_archive.php?current_issuance=202209202054&basin=atl&fdays=5}} Traveling west, the wave eventually emerged over the far eastern Atlantic Ocean on September 22.{{cite report|first=Brad J.|last=Reinhart|publisher=National Hurricane Center|date=January 25, 2023|accessdate=February 7, 2023|title=Tropical Storm Hermine (AL102022)|url=https://www.nhc.noaa.gov/data/tcr/AL102022_Hermine.pdf|format=PDF|series=Tropical Cyclone Report}} With favorable environmental conditions, including high sea surface temperatures, sufficient atmospheric moisture and instability, steady development was anticipated.{{cite report|first=Lisa|last=Bucci|publisher=National Hurricane Center|date=September 22, 2022|accessdate=October 4, 2022|title=Five-Day Graphical Tropical Weather Outlook|url=https://www.nhc.noaa.gov/archive/xgtwo/gtwo_archive.php?current_issuance=202209221753&basin=atl&fdays=5}} Scattered convection, some of it intense, accompanied the system.{{cite report|type=Technical Discussion|first=Andrew|last=Hagen|publisher=National Hurricane Center|date=September 22, 2022|accessdate=October 4, 2022|title=Tropical Weather Discussion|url=https://www.nhc.noaa.gov/archive/text/TWDAT/2022/TWDAT.202209220452.txt}} A broad area of low pressure consolidated within this wave early on September 23.{{cite report|type=Technical Discussion|first=Andrew|last=Hagen|publisher=National Hurricane Center|date=September 23, 2022|accessdate=October 4, 2022|title=Tropical Weather Discussion|url=https://www.nhc.noaa.gov/archive/text/TWDAT/2022/TWDAT.202209230338.txt}}{{cite report|first=Philippe|last=Papin|publisher=National Hurricane Center|date=September 23, 2022|accessdate=October 4, 2022|title=Five-Day Graphical Tropical Weather Outlook|url=https://www.nhc.noaa.gov/archive/xgtwo/gtwo_archive.php?current_issuance=202209231043&basin=atl&fdays=5}} The low moved north-northwest in response to a break in the eastern Atlantic subtropical ridge created by an upper-level trough. Throughout the day, convection organized into banding patterns and the low's center became more defined. In light of the increased organization, the NHC classified the system as Tropical Depression Ten at 12:00 UTC with the cyclone centered {{cvt|290|mi|order=flip}} east-northeast of the Cabo Verde Islands. A burst of convection on the cyclone's eastern side signaled the depression's intensification into a tropical storm late on September 23. Upon attaining gale-force winds, the NHC assigned it the name Hermine.{{cite report|first=Eric|last=Blake|publisher=National Hurricane Center|date=September 23, 2022|accessdate=October 4, 2022|title=Tropical Storm Hermine Discussion Number 2|url=https://www.nhc.noaa.gov/archive/2022/al10/al102022.discus.002.shtml|type=Technical Discussion}} Its maximum sustained winds peaked at {{convert|65|km/h|mph|round=5|abbr=on}} and pressure bottomed out at {{cvt|1003|hPa|inHg|2}}{{cite report|first=Eric|last=Blake|publisher=National Hurricane Center|date=September 23, 2022|accessdate=October 4, 2022|title=Tropical Storm Hermine Public Advisory Number 1|url=https://www.nhc.noaa.gov/archive/2022/al10/al102022.public.002.shtml}} Aircraft reconnaissance from NASA's Convective Processes Experiment-Cabo Verde recorded a central pressure of {{cvt|1006|hPa|inHg|2}} several hours later just outside the center, providing evidence for this estimation.

Modest water warmth and moderate wind shear produced by the trough north of the cyclone gave Hermine limited time to intensify before moving into an increasingly hostile environment on September 24.{{cite report|first=Andrew|last=Latto|publisher=National Hurricane Center|date=September 24, 2022|accessdate=October 4, 2022|title=Tropical Storm Hermine Discussion Number 3|url=https://www.nhc.noaa.gov/archive/2022/al10/al102022.discus.003.shtml|type=Technical Discussion}} The shear pushed dry, dusty air from the Saharan Air Layer into Hermine's circulation, inhibiting any further organization. The storm's surface circulation became increasingly separated to the west-southwest of the primary convection.{{cite report|first=John|last=Cangialosi|publisher=National Hurricane Center|date=September 24, 2022|accessdate=October 4, 2022|title=Tropical Storm Hermine Discussion Number 5|url=https://www.nhc.noaa.gov/archive/2022/al10/al102022.discus.005.shtml|type=Technical Discussion}} By 12:00 UTC, Hermine had degraded into a tropical depression with all its remaining convection situated far to the northeast over the Canary Islands.{{cite report|first=John|last=Cangialosi|publisher=National Hurricane Center|date=September 24, 2022|accessdate=October 4, 2022|title=Tropical Depression Hermine Discussion Number 6|url=https://www.nhc.noaa.gov/archive/2022/al10/al102022.discus.006.shtml|type=Technical Discussion}}{{cite report|first=Andrew|last=Latto|publisher=National Hurricane Center|date=September 25, 2022|accessdate=October 4, 2022|title=Tropical Depression Hermine Discussion Number 7|url=https://www.nhc.noaa.gov/archive/2022/al10/al102022.discus.007.shtml|type=Technical Discussion}} Sputtering convection remained during this time before the cyclone collapsed and degenerated into a remnant low around 00:00 UTC on September 25; it was situated about {{cvt|470|mi|order=flip}} west-southwest of the Canary Islands. The residual low continued toward the northeast before opening up into a trough by 06:00 UTC on September 26, marking its dissipation.

The cyclone's formation northeast of Cabo Verde is unusual, with only a handful of recorded instances within the Atlantic hurricane database dating back to 1851.{{cite web|first1=Jeff|last1=Maseters|first2=Bob|last2=Henson|publisher=Yale Climate Connections|date=September 22, 2022|accessdate=September 27, 2022|title=Cat 4 Fiona steams toward Canada; Caribbean disturbance 98L a major concern|url=https://yaleclimateconnections.org/2022/09/cat-4-fiona-steams-toward-canada-caribbean-disturbance-98l-a-major-concern/}} Hermine's particular track and effect in the Canary Islands is regarded as one without precedent according to the Institute of Oceanography and Global Change and the State Meteorological Agency. However, its relation to climate change could not be ascertained. Numeric modeling of climate change by the Climate Change Institute at the University of Maine indicate that environmental conditions would become increasingly hostile for tropical cyclones around the Canary Islands in a warming world.{{cite news|language=Spanish|agency=EFE|publisher=Radio Televisión Canaria|date=October 4, 2022|accessdate=October 4, 2022|title=Científicos analizan la excepcionalidad de la tormenta tropical Hermine|trans-title=Scientists analyze the exceptional nature of Tropical Storm Hermine|url=https://rtvc.es/cientificos-analizan-excepcionalidad-hermine/}}

Tracking close to West Africa, Hermine traversed part of the Atlantic Ocean known as the Canarian Route. This route is frequently used by migrants from several countries seeking to immigrate to the Canary Islands. Various media outlets attributed several incidents to the passage of Hermine;{{cite news|language=Spanish|first=Laura|last=Baptist|publisher=ABC Spain|date=September 25, 2022|accessdate=October 4, 2022|title='Hermine' arrolla Canarias: "Nos estamos inundando y acaba de empezar la alerta roja"|trans-title='Hermine' overwhelms the Canary Islands: "We are flooding and the red alert has just started"|url=https://www.abc.es/espana/canarias/hermine-arrolla-canarias-inundando-acaba-empezar-alerta-20220925181200-nt.html}} however, in the National Hurricane Center's post-storm report, no mention is made of these.

In anticipation of heavy rains, emergency services across the Canary Islands activated contingency plans to ensure public safety. The government issued their highest-level of warning on September 24 for heavy rain, wind, and flooding. Unlike the last tropical cyclone to impact the archipelago, Tropical Storm Delta in 2005 which caused extensive wind damage, the primary threat was rainfall. Total rainfall for the three-day period was forecast to equate to 10 to 15 times the normal monthly rainfall for September.{{cite news|newspaper=Canarian Weekly|date=September 24, 2022|accessdate=September 27, 2022|title=Tropical Storm Hermine will be felt from midday in the western Canary Islands|url=https://www.canarianweekly.com/posts/Tropical-storm-Hermine-will-be-felt-from-midday-in-the-western-Canary-Islands}} Schools throughout the Canary Islands were closed through September 26.{{cite news|newspaper=Canarian Weekly|date=September 23, 2022|accessdate=September 27, 2022|title=Schools are closed in the Canary Islands on Monday|url=https://www.canarianweekly.com/posts/Schools-are-closed-in-the-Canary-Islands-on-Monday}} On Tenerife, the Department of Roads dispatched 125 workers to conduct spot-checks and clear incidents as they were reported.{{cite news|agency=Tenerife Cabildo|newspaper=Canarian Weekly|date=September 24, 2022|accessdate=September 27, 2022|title=Tenerife activates the island's emergency plan in preparation of Tropical Storm Hermine|url=https://www.canarianweekly.com/posts/Tenerife-activates-the-Island-s-Emergency-Plan-in-preparation-of-Tropical-Storm-Hermine}} Incessant rain and low visibility prompted Binter Canarias to cancel all flights to and from Tenerife, La Gomera, El Hierro, and La Palma on September 25.

Aftermath

While the majority of roads were swiftly cleared of debris on Gran Canaria, portions of GC-1, GC-80, GC-301, GC-550, and GC-800 were severely damaged. The partial closure of the GC-1 led to significant traffic jams and repairs would not be completed for five months and would cost 1.2 million euros.
