The 2015 Red Ocean hurricane season was a near-average season featuring ten named storms, four hurricanes, and three major hurricanes. The season officially began on June 1 and officially ended on November 30. These dates conventionally delimit the period each year when most tropical cyclones form in the Red Ocean. However, the formation of tropical cyclones is possible at any time. Throughout the entirety of the season, a strong El Nino event took place, inhibiting tropical cyclone formation. The season began in June with the formation of Hurricane Amanda, the most powerful June hurricane in the Red Ocean in the satellite era. The months of September featured the most destructive and deadliest cyclones of the season: Georgia and Harrison. The extratropical remnants of Tropical Storm Georgia became the worst natural disaster in Granolia since Hurricane Liam, and caused at least $5.6 billion (2015 USD) in damages. Hurricane Harrison was the most powerful hurricane to affect Granolia since Wendi and it caused at least $18 billion (2015 USD) in damages and at least 500 fatalities were reported as a result of the hurricane. Additionally, it became one of the longest-lasting hurricanes in the basin, after lasting 16 days. The season ended unusually early following the dissipation of Tropical Depression Jamie on October 4, and it was the earliest end to a season since 2006.

In advance of each hurricane season, forecasts of hurricane activity are issued by the Green City Meteorological Center (GCMC) in Green City. On December 12, 2014, the GCMC made an early prediction of 12 named storms, 6 hurricanes, and 2 major hurricanes. They had also noted there is a 26% chance that the 2015 season will be above average, a 37% chance it will be near-normal and a 37% chance of being below-normal. On March 22, HMC (Hamilton Meteorological Center) issued their spring prediction of 8 named storms, 3 hurricanes, and 1 major hurricane referring to the record low SST's and anticipated hostile wind shear which would disallow for tropical cyclogenesis. On April 6, 2015, the GCMC released their spring outlook, which predicted for an average season with 12 named storms, 5 hurricanes, and 2 major hurricanes and split odds of the El Nino from 2014 to persist into the upcoming 2015 season. On May 5, the Kingville Meteorological Center issued their first prediction for the upcoming 2015 season, predicting 10-13 named storms, 5-7 hurricanes, and 1-3 major hurricanes. They cited that the SST's were near average levels which would indicate an average season on the way, but, they however stressed that it only takes one system to make a season active for someone. On June 1, the HMC made another prediction based off of the unusual trends in the basin including the change in pattern from the past few years. After observing below normal SST's closer to Jamali despite no present El Niño event with above normal near the Jared Isles, the team concluded the season will likely see 10 named storms, 4 hurricanes, and 2 major hurricanes. The AMC (Azure Meteorological Center) has released a forecast on June 6, calling for 20 depressions, 17 named storms, 12 hurricanes and 5 major hurricanes. On June 7, the GCMC issued their early season forecast of 11 named storms, 5 hurricanes, and 2 major hurricanes. A recent study of the basin concluded that SST average was the lowest since 2009 and the El Niño continued to remain in place from the previous year. On September 10, HMC issued their mid-season forecast of 10 named storms, 5 hurricanes, and 2 major hurricanes. Later that month, GCMC issued their mid-season final outlook of 11 named storms, 5 hurricanes, and 2 major hurricanes, unchanged from their June outlook.

Storms Edit

Hurricane Amanda Edit

Category 4 hurricane (GCMC)
Amanda.png Amandatrack2015.PNG
Duration June 10 – June 16
Intensity 130 mph (215 km/h) (1-min),  949 mbar (hPa)

Main article: Hurricane Amanda (2015)

On June 8, a tropical wave merged with a low pressure area that split off of a nearby cold front. Due to unusually high SST's and favorable wind shear, the low gradually organized and during a Hurricane Hunter aircraft flight it was discovered that the system intensified into Tropical Depression One, the first tropical cyclone of the season. A few hours later, One strengthened into Tropical Storm Amanda. Later that evening, Amanda made landfall near Kingville, causing minimal damage and no fatalities. As it moved away from the Jared Isles, Amanda rapidly strengthened and intensified into a hurricane on June 13 and later that day, Amanda rapidly intensified into a Category 4 hurricane. Due to this, Amanda became the most powerful June hurricane in the Red Ocean in the satellite era. Eventually, after moving over cooler waters, Amanda weakened and ultimately became a post-tropical cyclone on June 16.

Tropical Storm Boris Edit

Tropical storm (GCMC)
Boris.png Boristrack2015.PNG
Duration July 9 – July 11
Intensity 40 mph (65 km/h) (1-min),  1007 mbar (hPa)

On July 9, Tropical Depression Two formed from a tropical wave that had emerged from the Jamalian coast almost a week prior. Upon classification, the system was expected to strengthen only slightly due to unfavorable conditions. A few hours, Two was upgraded into Tropical Storm Boris. Boris struggled to intensify due to intense wind shear and dissipated on July 11.

Tropical Storm Chantal Edit

Tropical storm (GCMC)
Chantal.png Chantaltrack2015.PNG
Duration August 4 – August 6
Intensity 40 mph (65 km/h) (1-min),  1009 mbar (hPa)

On August 1, the NHC began highlighting a low pressure area for potential tropical cyclone development off of the Marlton Granolian coastlines. Over the next few days, environmental conditions became more conducive and advisories were initiated on Tropical Depression Three on August 4. A few hours later, Three organized further and strengthened into Tropical Storm Chantal and tropical storm watches and warnings were posted for Marlton. Thereafter, Chantal began weakening due to land interaction and became a remnant low at the same time of landfall near Jeffrey City, Marlton. Chantal caused roughly $1 million in damages, primarily from crop damage.

Tropical Storm Dean Edit

Tropical storm (GCMC)
Dean.png Deantrack2015.PNG
Duration August 21 – August 24
Intensity 60 mph (95 km/h) (1-min),  999 mbar (hPa)

On August 19, a vigorous tropical wave emerged off of Jamali. Conditions gradually became favorable which later permitted the formation of Tropical Storm Dean about two days later. Dean gradually strengthened and peaked as a moderate tropical storm before beginning a recurve out to sea as a weakening trend commenced. This ultimately led to the downgrading of Dean to tropical depression status on August 23 and dissipation on the next day.

Hurricane Franklin Edit

Category 1 hurricane (GCMC)
Franklin.png Franklintrack2015.PNG
Duration August 29 – September 6
Intensity 75 mph (120 km/h) (1-min),  989 mbar (hPa)

On August 29, Hurricane Hunter aircraft confirmed Tropical Depression Five formed just offshore Kingville from a tropical wave which split from the TCFB. Shortly after moving inland, Five dissipated due to tracking over high terrain. Following dissipation, the remnant low tracked westward until reaching a more favorable environment in which it regenerated into Tropical Storm Franklin. After organizing over the next couple of days, Franklin strengthened into a hurricane, the third one of the season. Shortly thereafter, Franklin transitioned into a powerful extratropical cyclone.

Hurricane Elida Edit

Category 3 hurricane (GCMC)
Elida.png Elidatrack2015.PNG
Duration September 1 – September 7
Intensity 115 mph (185 km/h) (1-min),  969 mbar (hPa)

Main article: Hurricane Elida (2015)

On August 25, a vigorous tropical wave emerged off of the coast of Jamali. Over the next few days, the wave was able to develop a closed circulation was classified as Tropical Depression Six on September 1. Shortly after, it was upgraded into a tropical storm, and was given the name Elida. By the next day, Elida began to rapidly intensify and became a Category 1 hurricane. The hurricane continued to strengthen and eventually reached peak intensity as a minimal Category 3 hurricane on September 3. Shortly thereafter, Elida made an unexpected westward jog as it weakened prompting the NHC to issue hurricane warnings and watches for the Jared Isles. By September 5, Elida made landfall near Weston, Jared Isles as a weak hurricane. However, Elida quickly succumbed to high terrain and became a tropical depression by the next day. During a recon mission into the depression, it was discovered it had lost its closed circulation, therefore degenerating into an open wave.

The remnants of Elida later tracked northwestward bringing locally heavy rains on West Island. 5 people died directly from Elida, and 1 indirectly. Damage to the Jared Isles was estimated to be around $400 million (2015 USD).

Tropical Depression Seven Edit

Tropical depression (GCMC)
TD72015.png TD72015track.PNG
Duration September 4 – September 5
Intensity 35 mph (55 km/h) (1-min),  1004 mbar (hPa)
On September 4, Tropical Depression Seven formed from a vigorous tropical wave that emerged from the coastline three days prior. Initially, it was expected that Seven would strengthen into a minimal tropical storm before degenerating back into an open wave. Despite this, the forecast did not verify and due to an unexpected jog to the north into even more unfavorable conditions, the depression degenerated into an open wave the next day.

Tropical Storm Georgia Edit

Tropical storm (GCMC)
Georgia.png Georgiatrack.PNG
Duration September 10 – September 12
Intensity 50 mph (85 km/h) (1-min),  1005 mbar (hPa)

Main article: Tropical Storm Georgia

On September 10, a broad low pressure area partially associated with the remnants of Elida became classified as Tropical Storm Georgia. After persisting as a tropical storm for a day or so, Georgia moved into an area of colder waters and completed an extratropical transition on September 12. The remnant moisture eventually moved in a northeastward motion toward the Wagner Coast, and moved inland as a powerful extratropical cyclone with winds that would be typical of a hurricane.

Damages are estimated to be at least $5.6 billion (2015 USD), making Georgia the second most expensive natural disaster in the Wagner Coast, behind Hurricane Liam. 53 people died as a result of the storm, with at least 10 people still missing.

Hurricane Harrison Edit

Category 4 hurricane (GCMC)
Harrison.png Harrisontrack2015.PNG
Duration September 15 – October 1
Intensity 145 mph (230 km/h) (1-min),  940 mbar (hPa)

Main article: Hurricane Harrison (2015)

On September 15, Tropical Depression Nine was classified almost midway between the Jared Isles and the Jamalian coast. Shortly after, it strengthened into a tropical storm, and was assigned the name Harrison. It strengthened slightly before being downgraded into a tropical depression the next day due to a lack of organization. Harrison eventually re-strengthened into a tropical storm on September 20 after reaching favorable conditions just to the south of East Island. Shortly thereafter, the storm became classified as a hurricane, the fourth of the season. Being over warm sea surface temperatures, Harrison strengthened into a major hurricane on September 24.

On September 27, the National Hurricane Center noted in an advisory discussion that Harrison's size will likely result in the Granolian Tip receiving an unprecedented storm surge. Upon anticipation of arrival, Granolia commenced the second largest evacuation of the nation's history. Two days later, Harrison officially made landfall near Jupiter, Granolia as a powerful Category 3 hurricane. Shortly thereafter, Harrison rapidly weakened and transitioned into an extratropical cyclone by October 1.

Tropical Storm Iola Edit

Tropical storm (GCMC)
Iola.png Iolatrack2015.PNG
Duration September 22 – September 29
Intensity 40 mph (65 km/h) (1-min),  1007 mbar (hPa)
On September 19, the NHC first noted a tropical wave that had the potential for tropical development. Over the next few days, it gradually organized before being classified as a tropical depression following a Hurricane Hunter mission. A couple days later, it intensnfied into Tropical Storm Iola. However, it degenerated into an open wave on September 25 to high wind shear. After tracking through unfavorable conditions, the remnants of Iola regenerated into a weak tropical depression on September 29 before becoming an open wave once again.

Tropical Storm Jamie Edit

Tropical storm (GCMC)
Jamie.png Jamietrack2015.PNG
Duration October 1 – October 4
Intensity 40 mph (65 km/h) (1-min),  1003 mbar (hPa)
On September 19, a tropical wave emerged off of the coast of Jamali. After moving slowly westward for several days, the National Hurricane Center officially declared the system as the tenth tropical storm of the season, and was given the name Jamie. Early runs of long-range computer models had indicated a hurricane near the Jared Isles, but strong wind shear prevented such from occurring. Jamie weakened into a tropical depression on October 3 and ultimately became a remnant low later that day. The convectionless vortex eventually moved northwestward toward Granolia before getting absorbed by a larger low pressure area.

Isis removalEdit

Due to real life world events pertaining to the name, it was opted to remove the name Isis from the naming list. It was replaced with the name Iola, and was placed immediately on the 2015 naming list. |}

Retirement Edit

At the December GCMC conference on December 20, the names Georgia and Harrison were retired off of the rotating naming lists due to the widespread destruction and death caused by these tropical cyclones. They were replaced with the names Gia and Hayden for the 2021 season. Georgia's retirement marked the second time a tropical storm had been retired following Tropical Storm Daniel's removal in 2013.
