The following is a list of events of the year 2018 in Iowa .
Des Moines is the capital and most populous city in the U.S. state of Iowa. It is the county seat of Polk County with parts extending into Warren County. It was incorporated on September 22, 1851, as Fort Des Moines, which was shortened to "Des Moines" in 1857. It is located on, and named after, the Des Moines River, which likely was adapted from the early French name, Rivière des Moines, meaning "River of the Monks". The city's population was 214,133 as of the 2020 census. The six-county metropolitan area is ranked 81st in terms of population in the United States, with 709,466 residents according to the 2020 census by the United States Census Bureau, and is the largest metropolitan area fully located within the state.
Ankeny is a city in Polk County, Iowa, United States and a suburb of the state capital of Des Moines, as part of the Des Moines-West Des Moines, IA metropolitan statistical area. As of the 2020 census, the population of Ankeny was 67,887, making it the seventh most populous city in the state. It is one of the fastest-growing cities in Iowa. Currently, the city's incorporated area totals 29.14 square miles.
A tornado emergency is an enhanced version of a tornado warning, which is used by the National Weather Service (NWS) in the United States during imminent, significant tornado occurrences in highly populated areas. Although it is not a new warning type from the NWS, issued instead within a severe weather statement or in the initial tornado warning, a tornado emergency generally means that significant, widespread damage is expected to occur and a high likelihood of numerous fatalities is expected with a large, strong to violent tornado.
Floods in the United States (2000–present) is a list of flood events which were of significant impact to the country during the 21st century, since 2000. Floods are generally caused by excessive rainfall, excessive snowmelt, storm surge from hurricanes, and dam failure.
A satellite tornado is a tornado that revolves around a larger, primary tornado and interacts with the same mesocyclone. Satellite tornadoes occur apart from the primary tornado and are not considered subvortices; the primary tornado and satellite tornadoes are considered to be separate tornadoes. The cause of satellite tornadoes is not known. Such tornadoes are more often anticyclonic than are typical tornadoes and these pairs may be referred to as tornado couplets. Satellite tornadoes commonly occur in association with very powerful, large, and destructive tornadoes, indicative also of the strength and severity of the parent supercell thunderstorm.
The June 2008 Midwestern United States floods were flooding events which affected portions of the Midwestern United States. After months of heavy precipitation, a number of rivers overflowed their banks for several weeks at a time and broke through levees at numerous locations. Flooding continued into July. States affected by the flooding included Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri and Wisconsin. The American Red Cross assisted the victims of flooding and tornadoes across seven states and the National Guard was mobilized to assist in disaster relief and evacuation.
The geography of Iowa includes the study of bedrock, landforms, rivers, geology, paleontology and urbanisation of the U.S. state of Iowa. The state covers an area of 56,272.81 sq mi (145,746 km2).
The environment of Iowa has been heavily affected by agricultural production since it became a U.S. state in 1846. However, there remain natural areas in Iowa that reflect a wide varieties of environmental niches.
The tornado outbreak sequence of May 5–10, 2015 was a six-day outbreak of tornado activity that affected the Great Plains of the United States in early May 2015. On May 6, strong tornadoes impacted the Oklahoma City area, along with rural parts of Kansas, Texas, Arkansas, South Dakota, and Nebraska. The outbreak coincided with major flooding, with large amounts of rain falling in parts of Nebraska, Kansas, Oklahoma, and Texas. The National Weather Service forecast office in Norman, Oklahoma issued a "flash flood emergency" for Oklahoma City following record-breaking rainfall that occurred in the area that evening. The outbreak sequence resulted in five tornado-related deaths, along with two flood-related deaths. A total of 127 tornadoes were confirmed and rated as a result of this outbreak sequence. Damage from the outbreak was estimated at $1.5 billion.
The 2018 Iowa gubernatorial election took place on November 6, 2018. Incumbent Republican governor Kim Reynolds ran for election to a full term, facing Democratic businessman Fred Hubbell, Libertarian Jake Porter, and independent candidate Gary Siegwarth.
Climate change in Iowa encompasses the effects of climate change, attributed to man-made increases in atmospheric carbon dioxide, in the U.S. state of Iowa.
On July 18, 2018, Mollie Cecilia Tibbetts, a 20-year-old University of Iowa student, disappeared while jogging near her home in Brooklyn, Iowa. A month later, police identified 24-year-old Cristhian Bahena Rivera as a suspect in connection with the disappearance; surveillance footage showed Rivera's car following Tibbetts on her jog. Rivera led police to the body of Tibbetts in a Poweshiek County cornfield on August 21. He was charged with first-degree murder. On May 28, 2021, Rivera was found guilty of first-degree murder. On August 30, 2021, Rivera was sentenced to life in prison without parole.
The following is a list of weather events that occurred in 2018.
On December 15, a rapidly-deepening low-pressure area contributed to a historic expanse of inclement weather across the Great Plains and Midwestern United States, resulting in an unprecedented December derecho and tornado outbreak across portions of the Northern United States, a region normally affected by snow and cold weather during this time of year. Non-thunderstorm winds spurred the formation of rapidly-moving fires across Colorado and western Kansas, with attendant dust and debris spreading eastward. From central Kansas northeastward into eastern Wisconsin, the powerful derecho led to hundreds of damaging wind reports. At least 57 hurricane-force wind reports were received by the National Weather Service, signaling the most prolific wind event in the United States dating back to at least 2004. Numerous embedded circulations within this rapidly-progressing derecho produced dozens of tornadoes, including 33 that were rated EF2. The culmination of non-thunderstorm, thunderstorm, and tornadic winds caused widespread damage to structures, trees, power lines, and vehicles across the Plains and Midwest. At least 600,000 people lost power on December 15, and temperatures dropped significantly across the affected region following the event, causing accumulating snow, which hindered cleanup and recovery efforts. The storm killed at least 5 people directly, as well as 2 people indirectly through wildfires partly spawned by the storm, and caused at least $1.8 billion in damages. The number of tornadoes in this event broke a record for largest outbreak in the month of December that had been set less than a week prior. The event also became one of the largest single-day outbreaks in recorded history, with 120 tornadoes occurring over an eight-hour period.
On July 19 and 20, 2018, an unexpected strong tornado outbreak affected Iowa and nearby areas. The event was triggered mostly by three supercells that produced several tornadoes across southeastern Iowa east and southeast of Des Moines. Two of the tornadoes reached EF3 intensity, affecting Pella and Marshalltown. These were the strongest tornadoes to hit Iowa since June 22, 2015, when another EF3 tornado struck near Lovilia. Of the 37 injuries, 13 occurred in Pella, and 23 in Marshalltown, and one the following day in Indiana. The event was also notable due to the Table Rock Lake duck boat accident that killed 17 people and injured 7 others at Table Rock Lake, Missouri.
A significant early spring tornado outbreak occurred during the afternoon and evening hours of March 5, 2022 in the Midwest, primarily in the state of Iowa, before transitioning to a damaging wind event across northern parts of Illinois and Indiana. Multiple tornadoes were reported, several of which were produced by a dominant supercell thunderstorm in central Iowa. One long-track, low-end EF4 tornado caused major damage near the towns of Winterset and Norwalk, resulting in six fatalities. Multiple other supercells spawned along an area of moderate destabilization in northern Missouri, prompting further tornado warnings in southern Iowa, as they entered a highly favorable environment for maturing. Large hail and damaging wind gusts accompanied the storms, which continued their passage across the Midwestern states into overnight. More tornadic weather was confirmed in Arkansas and Missouri the next day and into the early morning of March 7. In addition to that, straight line winds killed one person near Hazel, Kentucky when a semi trailer was blown over on US 641. Another non-tornadic fatality occurred in western New York as the storm approached.
Starting on the evening of July 13 and extending through July 16, 2024, an intense sequence of severe weather outbreaks affected much of the Midwestern and Northeastern United States. This included two significant derechoes that each had wind gusts exceeding 100 mph (160 km/h), as well as multiple tornado outbreaks that produced a combined 90 tornadoes across the affected areas. A ring of fire pattern fueled multiple systems that brought heavy rain and a tornado outbreak to northern Illinois, contributing to a partial dam failure in Washington County, Illinois, and multiple events of 90 mph (140 km/h) wind gusts. The sequence as a whole killed five people and injured three more.
In the afternoon hours of March 5, 2022, a large and violent tornado hit Winterset, located near Des Moines in the state of Iowa. The tornado produced heavy damage, and received an EF4 rating as a result. The tornado was the most powerful to touch down during the tornado outbreak of March 5–7, 2022, and the costliest tornado of 2022, inflicting $220 million worth of damages to the areas it impacted.
