1968 Tracy Tornado
The 1968 Tracy tornado was an extremely powerful F5 tornado that struck Tracy, Minnesota on Thursday, June 13, 1968, at around 7 o'clock. The tornado killed nine people and injured 125 others. The wind speeds of the tornado reached over 300 mph as it tracked through Murray, Lyon and Redwood counties in southwestern Minnesota. It is one of only two official F5 tornadoes that have occurred in Minnesota, although several other tornadoes that occurred before 1950 are estimated to have been F5 strength. The tornado destroyed 111 homes, caused major damage to 76, and caused minor damage to 114. Five businesses were destroyed and 15 others were damaged. Some homes in town only had their foundations left behind. A few farms outside of town were swept completely away, and extensive ground scouring occurred. An elementary school and 106 automobiles were destroyed, and a heavy boxcar was thrown more than a block by the storm. Two other boxcars were thrown 300 yards, and a steel I-beam ...

United States Dollar
The United States dollar (symbol: $; code: USD; also abbreviated US$ or U.S. Dollar, to distinguish it from other dollar-denominated currencies; referred to as the dollar, U.S. dollar, American dollar, or colloquially buck) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The monetary policy of the United States is conducted by the Federal Reserve System, which acts as the nation's central bank. The U.S. dollar was originally defined under a bimetallic standard of (0.7735 troy ounces) fine silver or, from 1837, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Of Minnesota
Minnesota has a humid continental climate, with hot summers and cold winters. Minnesota's location in the Upper Midwest allows it to experience some of the widest variety of weather in the United States, with each of the four seasons having its own distinct characteristics. The area near Lake Superior in the Minnesota Arrowhead region experiences weather unique from the rest of the state. The moderating effect of Lake Superior keeps the surrounding area relatively cooler in the summer and warmer in the winter, giving that region a smaller yearly temperature variation. On the Köppen climate classification, much of the southern third of Minnesota—roughly from the Twin Cities region southward—falls in the hot summer zone (''Dfa''), and the northern two-thirds of Minnesota falls in the warm summer zone (''Dfb''). Winter in Minnesota is characterized by cold (below freezing) temperatures. Snow is the main form of winter precipitation, but freezing rain, sleet, and occasionally rai ...

Tornadoes Of 1968
This page documents the tornadoes and tornado outbreaks of 1968, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes. Two F5 tornadoes struck Iowa in the Charles City and Maynard areas, combined they claimed 18 lives and this was one of very few cases in history where two F5 or EF5 tornadoes hit the same state, on the same day. Events United States yearly total January There were 5 confirmed tornadoes in the United States in January, all rated F1 or F0. February There were 7 confirmed tornadoes in the United States in February. February 19 An F2 tornado moved through the North Miami Beach, Florida, destroying two homes, damaging 144 homes and businesses, and injuring 21 people. An F1 tornado also struck west of Miami. March There were 28 confirmed tornadoes in the Unite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

F5 Tornadoes
This is a list of tornadoes which have been officially or unofficially labeled as F5, EF5, T10-T11, IF5, or an equivalent rating, the highest possible ratings on the various tornado intensity scales. These scales – the Fujita scale, the Enhanced Fujita scale, the International Fujita scale, and the TORRO tornado intensity scale – attempt to estimate the intensity of a tornado by classifying the damage caused to natural features and man-made structures in the tornado's path. Tornadoes are among the most violent known meteorological phenomena. Each year, more than 2,000 tornadoes are recorded worldwide, with the vast majority occurring in North America and Europe. In order to assess the intensity of these events, meteorologist Ted Fujita devised a method to estimate maximum wind speeds within tornadic storms based on the damage caused; this became known as the Fujita scale. The scale ranks tornadoes from F0 to F5, with F0 being the least intense and F5 being the mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of North American Tornadoes And Tornado Outbreaks
These are some notable tornadoes, tornado outbreaks, and tornado outbreak sequences that have occurred in North America. #''The listing is U.S.-centric, with greater and more consistent information available for U.S. tornadoes. Some North American outbreaks affecting the U.S. may only include tornado information from the U.S.'' #''Exact death and injury counts are not possible, especially for large events and events before 1950.'' #''Prior to 1950 in the United States, only significant tornadoes (rated F2 or higher or causing a fatality) are listed for the number of tornadoes in outbreaks. These ratings are estimates from tornado expert Tom Grazulis and are not official.'' #''Due to increasing detection, particularly in the U.S., numbers of counted tornadoes have increased markedly in recent decades although number of actual tornadoes and counted significant tornadoes has not. In older events, the number of tornadoes officially counted is likely underestimated.'' #''Historical c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boxcar
A boxcar is the North American (AAR) term for a railroad car that is enclosed and generally used to carry freight. The boxcar, while not the simplest freight car design, is considered one of the most versatile since it can carry most loads. Boxcars have side sliding doors of varying size and operation, and some include end doors and adjustable bulkheads to load very large items. Similar covered freight cars outside North America are covered goods wagons and, depending on the region, are called ''goods van'' ( UK and Australia), ''covered wagon'' ( UIC and UK) or simply ''van'' (UIC, UK and Australia). Use Boxcars can carry most kinds of freight. Originally they were hand-loaded, but in more recent years mechanical assistance such as forklifts have been used to load and empty them faster. Their generalized design is still slower to load and unload than specialized designs of car, and this partially explains the decline in boxcar numbers since World War II. The ...

Fujita Scale
The Fujita scale (F-Scale; ), or Fujita–Pearson scale (FPP scale), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation. The official Fujita scale category is determined by meteorologists and engineers after a ground or aerial damage survey, or both; and depending on the circumstances, ground-swirl patterns (cycloidal marks), weather radar data, witness testimonies, media reports and damage imagery, as well as photogrammetry or videogrammetry if motion picture recording is available. The Fujita scale was replaced with the Enhanced Fujita scale (EF-Scale) in the United States in February 2007. In April 2013, Canada adopted the EF-Scale over the Fujita scale along with 31 "Specific Damage Indicators" used by Environment Canada (EC) in their ratings. Background The scale was introduced in 1971 by Ted Fujita of the University of Chicago, in collaboration with Allen Pearson, head of the National ...

Storm Prediction Center
The Storm Prediction Center (SPC) is a US government agency that is part of the National Centers for Environmental Prediction (NCEP), operating under the control of the National Weather Service (NWS), which in turn is part of the National Oceanic and Atmospheric Administration (NOAA) of the United States Department of Commerce (DoC). Headquartered at the National Weather Center in Norman, Oklahoma, the Storm Prediction Center is tasked with forecasting the risk of severe thunderstorms and tornadoes in the contiguous United States. It issues convective outlooks, mesoscale discussions, and watches as a part of this process. Convective outlooks are issued for the following eight days (issued separately for Day 1, Day 2, Day 3, and Days 4–8), and detail the risk of severe thunderstorms and tornadoes during the given forecast period, although tornado, hail and wind details are only available for Days 1 and 2. Day 3, as well as 4–8 use a probabilistic scal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minnesota
Minnesota () is a state in the upper midwestern region of the United States. It is the 12th largest U.S. state in area and the List of U.S. states and territories by population, 22nd most populous, with over 5.75 million residents. Minnesota is home to western prairies, now given over to intensive agriculture; deciduous forests in the southeast, now partially cleared, farmed, and settled; and the less populated Laurentian Mixed Forest Province, North Woods, used for mining, forestry, and recreation. Roughly a third of the state is Forest cover by state and territory in the United States, covered in forests, and it is known as the "Land of 10,000 Lakes" for having over 14,000 bodies of fresh water of at least ten acres. More than 60% of Minnesotans live in the Minneapolis–Saint Paul metropolitan area, known as the "Twin Cities", the state's main political, economic, and cultural hub. With a population of about 3.7 million, the Twin Cities is the List of metropolitan stati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
