The 2001–02 Australian region cyclone season was a slightly below average tropical cyclone season.
 It officially started on 1 November 2001, and ended on 30 April 2002.
 However, the formation of Tropical Cyclone Alex on 26 October 2001 marked an earlier beginning to the season, and the season extended past the official end of the season when Tropical Cyclone Upia formed on 25 May 2002.
 The regional tropical cyclone operational plan also defines a "tropical cyclone year" separately from a "tropical cyclone season"; the "tropical cyclone year" began on 1 July 2001 and ended on 30 June 2002.
The 2007 Midwest flooding was a major flooding event that occurred in the Midwestern United States in the third week of August 2007.
 While Hurricane Dean was affecting the Yucatán Peninsula and the Gulf of Mexico, and Tropical Storm Erin was affecting Oklahoma and Texas, a persistent storm system hung over the Midwest for several days, causing repeated flash flooding in the US states of Illinois, Indiana, Iowa, Minnesota, Ohio, and Wisconsin.
 Cool Canadian air clashed with large quantities of warm moist air from the Gulf, producing torrential rains along a stationary front.
 Eighteen deaths across the central United States were attributed to the resulting flooding.
 Seven Minnesota counties, eight Ohio counties, fourteen counties in Wisconsin, and seven counties in Illinois were declared Federal Disaster Areas.
The 2009–10 South Pacific cyclone season began on December 3, 2009 with the formation of Tropical Disturbance 01F, 32 days after the cyclone season had officially begun on November 1, 2009.
 The season ended on April 30, 2010.
 These dates conventionally delimit the period of each year when most tropical cyclones form in the southern Pacific Ocean east of 160°E.
 Additionally, the regional tropical cyclone operational plan defines a "tropical cyclone year" separately from a "tropical cyclone season"; the "tropical cyclone year" began on July 1, 2009 and ended on June 30, 2010.
 Tropical cyclones between 160°E and 120°W and north of 25°S are monitored by the Fiji Meteorological Service.
 Those that move south of 25°S are monitored by the Tropical Cyclone Warning Centre in Wellington, New Zealand.
 The first tropical disturbance of the season formed on December 3, about 1015 km (700 mi) to the north of Suva, Fiji and later intensified into Tropical Cyclone Mick.
 The last system, 15F, dissipated on April 5 of the following year.
The list of Florida hurricanes from 1975 to 1999 encompasses 83 Atlantic tropical cyclones that affected the U.S. state of Florida.
 Collectively, tropical cyclones in Florida during the time period resulted in at least $45 billion (2008 USD) in damage, primarily from Hurricane Andrew.
 Additionally, tropical cyclones in Florida were directly responsible for 54 fatalities during the period.
 Several tropical cyclones produced over 20 inches (500 mm) of rainfall in the state, including Hurricane Georges which is the highest total during the time period.
 The 1985 season was the year with the most tropical cyclones affecting the state, with a total of eight systems.
 Every year included at least one tropical cyclone affecting the state.
The list of Florida hurricanes from 2000 to the present has been marked by several devastating North Atlantic hurricanes; as of 2017, 79 tropical or subtropical cyclones have affected the U.S. state of Florida.
 Collectively, cyclones in Florida during the time period resulted in more than $73 billion in damage (2017 USD).
 Additionally, tropical cyclones in Florida were responsible for 145 direct fatalities and at least 92 indirect casualties during the period.
 Eight cyclones affected the state in both 2004 and 2005, which were the years with the most tropical cyclones affecting the state.
 Every year included at least one tropical cyclone affecting the state.
 During the 2004 season, more than one out of every five houses in the state received damage.
 After Wilma in 2005, it would be 11 years until another hurricane would strike the state, and 12 years until another major hurricane would strike the state.
Tropical Storm Erin was the second-largest tropical cyclone to make landfall in the United States in the 2007 Atlantic hurricane season.
 The fifth named storm of the season, it formed in the Gulf of Mexico on August 14 from a persistent area of convection.
 It attained tropical storm status the next day, and on August 16, 2007 Erin made landfall near Lamar, Texas, and persisted over land across Texas before moving northward into Oklahoma.
 Due to the brown ocean effect, Erin intensified after landfall.
 The storm resulted in 21 fatalities and worsened an already-severe flooding issue in Texas.
Severe Tropical Cyclone Donna was the strongest off-season South Pacific tropical cyclone on record during the month of May.
 The twenty-first tropical disturbance, third named storm, and second severe tropical cyclone of the annual cyclone season, Donna formed from an area of disturbed weather that was first monitored west-northwest of Fiji on 1 May 2017.
 The disturbance drifted eastward amid an increasingly favorable environment, and it was designated Tropical Depression 21F late on 2 May.
 Twelve hours later, it intensified into a Category 1 on the Australian tropical cyclone scale and was designated Tropical Cyclone Donna as the storm's motion shifted west and then south.
 After reaching its initial peak as a Category 4 cyclone early on 6 May, the effects of wind shear and upwelling caused the storm to weaken.
 However, it reintensified into a Category 5 cyclone on 8 May.
 Soon after, Donna entered a region of strong westerly flow and began to rapidly weaken.
 Continuing to accelerate in a southerly direction, Donna eventually weakened into a tropical low on 10 May.
 By 16 May, Donna's remnants had fully dissipated.
The 2002–03 Australian region cyclone season included Cyclone Inigo, which tied Cyclone Gwenda in 1999 as the most intense tropical cyclone on record in the Australian basin.
 It began on 1 November 2002 and ended on 30 April 2003.
 The regional tropical cyclone operational plan also defines a "tropical cyclone year" separately from a "tropical cyclone season", which runs from 1 July 2002 to 30 June 2003.
 These dates conventionally delimit the period of each year when most tropical cyclones form in the Australian region, which is defined as in the southern hemisphere between 90°E and 180°E.
 The season's ten tropical depressions existed within these dates, with the first, designated as Tropical Cyclone 07S, entering the basin on 27 December 2002.
 The last system, Cyclone Epi, dissipated on 6 June 2003.
 Tropical cyclones in this area were monitored by four Tropical Cyclone Warning Centres (TCWCs): the Australian Bureau of Meteorology (BOM) in Perth, Darwin, and Brisbane and one in Port Moresby, Papua New Guinea.
Intense Tropical Cyclone Indlala was a tropical cyclone that caused severe damage in Madagascar in 2007.
 The 12th tropical system, 9th named storm, and 5th intense tropical cyclone of the 2006–07 South-West Indian Ocean cyclone season, Indlala developed on March 3, 2007 as a tropical depression.
 It moved westward and was upgraded to Tropical Depression 12 on March 6.
 In an area of favorable environment for tropical cyclone formation, it tracked westward, steadily intensifying.
 It was upgraded to Moderate Tropical Storm Indlala on March 12.
 It continued to intensify and became a Severe Tropical Storm the next day.
 It then became a Tropical cyclone that same day as it moved westward and was upgraded to Intense Tropical Cyclone Indlala as it reached its peak intensity of 155 mph shortly before making landfall in the northeastern section of Madagascar.
Severe Tropical Cyclone Gene was the deadliest storm as well as the most damaging tropical cyclone of the 2007–08 South Pacific cyclone season east of 160ºE.
 RSMC Nadi monitored Gene as the 12th tropical disturbance, as well as the fourth tropical cyclone and the third severe tropical cyclone to form west of 160ºE during the 2007–08 South Pacific cyclone season.
 Gene was also recognised by RSMC Nadi as the fifth tropical cyclone and fourth severe tropical cyclone to form within the South Pacific Ocean during the 2007-08 season.

Question: In 2007, in which region was this tropical cyclone affecting Oklahoma and Texas formed?
Answer: the Gulf of Mexico
