Question: In 2007, in which region was this tropical cyclone affecting Oklahoma and Texas formed?

<P0-S0> 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. <P0-S1>  It began on 1 November 2002 and ended on 30 April 2003. <P0-S2>  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. <P0-S3>  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. <P0-S4>  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. <P0-S5>  The last system, Cyclone Epi, dissipated on 6 June 2003. <P0-S6>  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. <SEP> <P1-S0> Tropical Storm Erin was the second-largest tropical cyclone to make landfall in the United States in the 2007 Atlantic hurricane season. <P1-S1>  The fifth named storm of the season, it formed in the Gulf of Mexico on August 14 from a persistent area of convection. <P1-S2>  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. <P1-S3>  Due to the brown ocean effect, Erin intensified after landfall. <P1-S4>  The storm resulted in 21 fatalities and worsened an already-severe flooding issue in Texas. <SEP> <P2-S0> The 2007 Midwest flooding was a major flooding event that occurred in the Midwestern United States in the third week of August 2007. <P2-S1>  Cool Canadian air clashed with large quantities of warm moist air from the Gulf, producing torrential rains along a stationary front. <P2-S2>  Eighteen deaths across the central United States were attributed to the resulting flooding. <P2-S3>  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. <P2-S4>  Seven Minnesota counties, eight Ohio counties, fourteen counties in Wisconsin, and seven counties in Illinois were declared Federal Disaster Areas. <SEP> <P3-S0> Intense Tropical Cyclone Indlala was a tropical cyclone that caused severe damage in Madagascar in 2007. <P3-S1>  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. <P3-S2>  It moved westward and was upgraded to Tropical Depression 12 on March 6. <P3-S3>  In an area of favorable environment for tropical cyclone formation, it tracked westward, steadily intensifying. <P3-S4>  It was upgraded to Moderate Tropical Storm Indlala on March 12. <P3-S5>  It continued to intensify and became a Severe Tropical Storm the next day. <P3-S6>  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.
