Question: Who named the storm which affected parts of the Upper Midwest of the United States, from October 31 to November 3, 1991

<P0-S0>  Over the last week of October 1991 a large storm system over the Atlantic Ocean (1991 Perfect Storm) blocked most of the weather patterns over the eastern half of the United States, and in turn moisture from the Gulf of Mexico was funneled straight northward over the affected region. <P0-S1>  By the time the precipitation stopped falling many cities in the eastern half of Minnesota and northwestern Wisconsin had witnessed record early-season snowfall accumulations, while parts of southern Minnesota and northern Iowa were crippled by a large ice storm. <P0-S2> The 1991 Halloween blizzard was powerful storm that caused a period of heavy snowfall and ice accumulation, which affected parts of the Upper Midwest of the United States, from October 31 to November 3, 1991. <P0-S3>  Arctic air that was pulled southward behind the storm had combined with the heavy snow pack to produce many record low temperatures. <P0-S4>  Between the blizzard and the ice storm 22 people were killed and over 100 were injured. <SEP> <P1-S0> The Early December 2007 North American winter storm was a major winter storm which affected the majority of the United States and portions of southern Canada from November 29 to December 5, hitting the Intermountain West and Midwestern United States, the Great Lakes region and the Northeast. <P1-S1>  The storm brought significant snows to portions of the Upper Midwest, Great Plains and Great Lakes regions of the United States and Canada on December 1 with a major winter storm for Quebec, Ontario and parts of the Northeast region on December 2 and 3 as well as the Canadian Maritimes on December 4 and 5. <P1-S2>  The system was also responsible for a major ice storm across the Midwestern states which caused disruptions to several major cities including Des Moines, Chicago, Detroit, Milwaukee and Toronto. <P1-S3>  The storm was blamed for at least 16 deaths across nine US states and one Canadian province. <P1-S4>  10 traffic deaths had been reported, as of 2 December 2007. <SEP> <P2-S0> Tropical Storm Ignacio was a weak tropical cyclone affected parts of the western United States in August 1997. <P2-S1>  The 12th tropical cyclone and 9th named storm of the 1997 Pacific hurricane season, Ignacio formed west of Mexico from a weather disturbance embedded within a more broad system. <P2-S2>  It was classified as a tropical depression on August 17, and although it quickly intensified into a tropical storm, harsher environmental conditions caused it to begin weakening as the cyclone moved northward. <P2-S3>  On August 19, Ignacio transitioned into an extratropical cyclone as it approached California, where its remnants produced unprecedented August rainfall, numerous traffic accidents, and 78,000 power outages. <SEP> <P3-S0> The 1991 Perfect Storm, also known as The No-Name Storm (especially in the years immediately after it took place) and the Halloween Gale, was a nor'easter that absorbed Hurricane Grace and ultimately evolved back into a small unnamed hurricane late in its life cycle. <P3-S1>  The initial area of low pressure developed off Atlantic Canada on October 29. <P3-S2>  Forced southward by a ridge to its north, it reached its peak intensity as a large and powerful cyclone. <P3-S3>  The storm lashed the east coast of the United States with high waves and coastal flooding before turning to the southwest and weakening. <P3-S4>  Moving over warmer waters, the system transitioned into a subtropical cyclone before becoming a tropical storm. <P3-S5>  It executed a loop off the Mid-Atlantic states and turned toward the northeast. <P3-S6>  It later received the name "the Perfect Storm" (playing off the common expression) after a conversation between Boston National Weather Service forecaster Robert Case and author Sebastian Junger. <P3-S7>  On November 1 the system evolved into a full-fledged hurricane with peak winds of 75 miles per hour (120 km/h), although the National Hurricane Center left it unnamed to avoid confusion amid media interest in the predecessor extratropical storm. <P3-S8>  The system was the fourth hurricane and final tropical cyclone in the 1991 Atlantic hurricane season. <P3-S9>  The tropical system weakened, striking Nova Scotia as a tropical storm before dissipating.
