Minnesota Hit by Powerful Storms and Multiple Tornadoes
Minnesota experienced a night of intense weather on Saturday, June 28, and early Sunday, June 29, 2025, as severe storms swept across the state, bringing heavy rainfall, strong winds, and several reported tornadoes. The Twin Cities metropolitan area, along with western and central Minnesota, bore the brunt of the activity, prompting numerous weather alerts and safety warnings. FOX 9 reported live updates as the storms unfolded.
Observed tornadoes were reported in multiple locations. In far western Minnesota, two tornadoes were sighted near Canby on Saturday evening, occurring approximately two hours apart. As the storm system progressed, three additional tornadoes were observed in the southwest Twin Cities metro early Sunday morning. Specific areas like Waconia and St. Bonifacius also reported tornado activity, leading to immediate tornado warnings for Carver and Scott counties. The National Weather Service (NWS) extended a tornado watch to include Hennepin, Ramsey, and Carver counties until 1 a.m. Sunday, indicating conditions were favorable for tornado development.
Beyond tornadoes, the storms delivered a range of hazards. Heavy rainfall raised concerns about flash flooding, with warnings issued for Lac Qui Parle, Yellow Medicine, Sherburne, and Wright counties. A river flood warning was also in effect for several counties, including Chippewa, Lac Qui Parle, Yellow Medicine, Renville, Redwood, and Carver. Damaging wind gusts and frequent lightning were also prevalent throughout the affected regions. The NWS had previously indicated a Level 2 risk of severe weather for much of Minnesota, including the Twin Cities, from Saturday evening into Sunday morning, highlighting threats of large hail, strong winds, isolated tornadoes, and localized flooding.
Looking ahead, the forecast for Sunday indicates partly sunny conditions with a low risk of severe weather, and high temperatures expected to reach the mid-80s, signaling a more pleasant start to the work week.
Understanding Tornado Alerts: Watch, Warning, and Emergency
In light of such severe weather events, it’s crucial for the public to understand the different levels of tornado alerts issued by the National Weather Service. These alerts are designed to communicate the severity and immediacy of the threat, guiding appropriate safety actions. According to the NWS, there are three primary alerts: Tornado Watch, Tornado Warning, and Tornado Emergency.
- Tornado Watch: Be Prepared! A Tornado Watch means that conditions are favorable for tornadoes to form in and near the designated watch area. This alert is typically issued by the Storm Prediction Center and covers a large geographical region, sometimes spanning multiple counties or even states. During a watch, individuals should review their emergency plans, gather supplies, and identify their safe room, preparing to act quickly if a warning is issued.
- Tornado Warning: Take Action! A Tornado Warning signifies that a tornado has either been sighted by trained spotters or indicated by weather radar, posing an imminent danger to life and property. These warnings are issued by local NWS forecast offices and cover a much smaller, more specific area. Upon receiving a tornado warning, immediate action is required: move to an interior room on the lowest floor of a sturdy building, away from windows. Those in mobile homes, vehicles, or outdoors should seek the closest substantial shelter.
- Tornado Emergency: Seek Shelter Immediately! This is the highest and most urgent alert level issued by the NWS. A Tornado Emergency is declared when a violent tornado has touched down, with confirmed catastrophic damage and a severe threat to human life. This unofficial, enhanced wording is added to a tornado warning product when the situation is exceptionally dangerous.
Modern weather surveillance technology, such as Doppler weather radar, plays a critical role in detecting storm rotation and issuing early warnings. However, visual sightings from trained storm spotters and the public remain invaluable for ground truthing. The NWS also utilizes an Impact Based Warning (IBW) system, adding tags like “Radar Indicated,” “Observed,” “Considerable,” and “Catastrophic” to warnings to better convey the severity of the threat.
Historically, public tornado forecasts and warnings faced initial resistance. The U.S. Weather Bureau (now NWS) once prohibited the use of the word “tornado” in forecasts, fearing public panic. This ban was officially lifted in 1950, and the first official tornado forecast was made in 1948 by U.S. Air Force Captain Robert C. Miller and Major Ernest Fawbush. The broadcast media ban on tornado warnings was also lifted in 1954, thanks to meteorologist Harry Volkman, who broadcast the first televised tornado warning in Oklahoma City. These advancements have significantly improved warning times and reduced tornado-related fatalities over the decades. While outdoor sirens are activated in many communities, like Wheaton, IL, to alert those outside, residents are advised to rely on multiple sources such as local broadcast media, weather radio, and mobile alerts for comprehensive and timely information, as sirens may not be audible indoors. Staying informed through various channels is paramount for safety during severe weather events.
