Tornadoes Expected to Strike Multiple States This Weekend in One of the Worst Seasons This Decade
The National Weather Service's Storm Prediction Center has forecast severe thunderstorms with scattered tornadoes—some of them intense—across parts of Kentucky, Missouri, Illinois, Indiana, Tennessee, Arkansas and Ohio for the afternoon and evening of May 16.
'Today we're expecting a severe weather outbreak across the mid-Mississippi, Tennessee and Ohio valleys,' says Jenni Pittman, a meteorologist and deputy chief of the Science and Technology Integration division at the National Weather Service's Central Region Headquarters. These regions stretch farther east than the historically prevalent 'Tornado Alley' of the mid- to late 1900s.

'Then we see a renewed chance for severe weather Sunday, continuing Monday and continuing Tuesday as well,' Pittman says. 'A lot of the risks on Sunday through Tuesday are going to be from the High Plains pretty much through the Midwest.' National Weather Service maps show these risks concentrated in Kansas and Oklahoma.
This weekend's predicted tornadoes would follow a slight lull in the region, she adds. 'We've had a little bit of a break here in May, which is typically a pretty busy severe weather month,' Pittman says. 'April was very active, and the rest of May does look pretty active as well.'
As of May 15, the National Weather Service has tallied 779 tornadoes in its local storm reports—a preliminary number but a helpful metric for tracking the season's severity. For comparison, between 2005 and 2015, that same tally averaged 624; between 2010 and 2024, it was 592.
'As of mid-May, the U.S. is running well above the typical number of tornadoes to this point in the year,' says Rich Thompson, chief of forecast operations for the Storm Prediction Center.
This year to date also stands out against individual years. The most active tornado season of recent years was 2011, when hundreds of storms struck in late April; by mid-May the tally stood at more than 1,300 storms, with more than 2,200 by the end of the year.
That year also demonstrated the close connection between just a few days of serious storms and a bad season. 'Intense tornadoes are disproportionately responsible for damage, injuries and deaths, and such tornadoes are more common on a few 'outbreak' days,' Thompson says. 'Thus, the number of outbreak days often determines the severity of the season, with 2011 being the prime example of multiple high-impact tornado outbreaks.'
Overall, this year is more on par with last year, which had seen 815 tornado reports by this point in the season. Notably, one third of those storms have occurred during just three outbreak days in March and April, Thompson says.
If you live in an area where tornadoes are forecast, follow local weather and emergency response offices closely. In general, experts recommend having supplies available to shelter in place and having a safety plan for pets as well as humans. Pittman also recommends that people have multiple ways to stay on top of weather alerts (such as through broadcasts on television and on battery-powered radios, outdoor sirens and fully charged mobile phones).
During an event, the National Weather Service recommends that people living where a severe thunderstorm watch is active head to 'an interior room on the lowest floor of a sturdy building.'
If you're caught away from shelter, the calculus becomes more complicated. In a vehicle, if a storm is still at a distance, you may be able evade it by driving at a right angle to the tornado's apparent approach. If already caught in the winds, park instead, and either keep your seat belt fastened and protect your head and neck or get out of the car if there's someplace safe to lie below the elevation of the roadway. Avoid sheltering under bridges, however, which don't offer much protection, experts note.

Millions Told To Monitor Unusual Fatigue, Palpitations
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Millions of Americans have been urged to watch out for unusual fatigue and palpitations amid concerns over high air pollution levels. The National Weather Service (NWS) issued a series of air quality alerts on Tuesday for large swathes of Minnesota, Wisconsin, New York, Connecticut, New Hampshire, Rhode Island, Massachusetts, Colorado, Texas and California. The warnings mean ground-level ozone and particulate concentrations are forecast to reach dangerous levels. In some areas, the pollution comes from drifting wildfire smoke. Why It Matters The NWS warned that the general public as well as sensitive groups — children, seniors, and individuals with preexisting respiratory or heart conditions—might experience health effects linked to poor air quality in the affected regions. "People with heart disease: symptoms such as palpitations, shortness of breath, or unusual fatigue may indicate a serious problem. If you have any of these, contact your health care provider," it said. "People with asthma: follow your asthma action plan and keep quick relief medicine handy." It added: "Sensitive groups, such as people with lung disease, heart disease, and children and older adults, should avoid prolonged or heavy exertion." The Statue of Liberty is seen through haze from Canadian wildfires earlier in August. The Statue of Liberty is seen through haze from Canadian wildfires earlier in August. Yuki Iwamura/AP What To Know In Connecticut and Rhode Island, Air Quality Action Days have been issued until 11 p.m. on Tuesday, covering urban areas such as New Haven, Hartford, Providence and Newport. The alerts mean that ground level ozone levels may approach or exceed unhealthy standards. Air quality alerts have been issued in New York and Massachusetts until 11 p.m., covering areas including the Bronx, Queens, Boston and Plymouth. In New Hampshire, an air quality alert has been issued until 10 p.m. In Minnesota, an air quality alert for fine particle pollution has been issued until 9 a.m., and in Wisconsin an air quality advisory has been issued for most northern counties until 3 p.m. Meanwhile in Colorado, an air quality health advisory for wildfire smoke has been issued for a number of western counties until 9 a.m. following the Stoner Mesa fire. In California, an air quality alert has been issued due to harmful levels of particle pollution from windblown dust in the Coachella Valley. And in Texas, an Ozone Action Day has been issued for the Dallas-Fort Worth area. What People Are Saying The Colorado Department of Public Health and Environment said: "If smoke is thick or becomes thick in your neighborhood you may want to remain indoors. This is especially true for those with heart disease, respiratory illnesses, the very young, and older adults. Consider limiting outdoor activity when moderate to heavy smoke is present. Consider relocating temporarily if smoke is present indoors and is making you ill." California's South Coast Air Quality Management District said: "Particle pollution can get deep into the lungs and cause serious health problems such as asthma attacks, heart and lung disease symptoms, and increased risk of lung infections. Everyone can be affected, but sensitive groups such as people with lung or heart disease, older adults, people who are pregnant, children, and those who spend a lot of time outdoors are at greater risk." Jonathan Grigg, a professor of pediatric respiratory and environmental medicine at Queen Mary University of London, previously told Newsweek that there are "very clear links" between inhaling particles and earlier death from both respiratory and cardiovascular diseases. He added: "There are vulnerable groups and classically they are children because they've got an extra issue to do with their lungs developing, whereas our lungs are not developing as adults." What Happens Next The majority of the air quality alerts are currently set to remain in force until late Tuesday. Regular updates regarding air pollution levels are issued on the NWS website and on the Environmental Protection Agency's AirNow interactive map.

Frustration grows in Paterson, N.J. on Day 5 of boil water advisory after water main break
Officials are expected to give another update Tuesday morning on the massive water main break in Paterson, N.J. that is impacting nearly 200,000 people. The area is under a boil water advisory for a fifth straight day. Crews are said to have been making progress repairing the break in a 30-inch pipe near Hinchliffe Stadium that triggered the advisory. Monday night, officials said crews finally isolated a leak, and that water pressure is rising. Work has been underway since early Friday morning to repair the broken 140-year-old water main, which left close to 200,000 people in Paterson, Prospect Park, Haledon and North Haledon with low water pressure, or none at all. The mayors of all four towns are expected to hold another joint press conference Tuesday morning at 10:30 a.m. On Monday, they asked families for patience, saying three major pipelines run through the area, and crews needed time to figure out which one was the problem. "One of the complicated aspects of it, with the 140-year-old infrastructure, we don't even have good, reliable drawings of what's in the ground. It's 20, 30 feet deep. It's not easy to access," said Jim Mueller, executive director of the Passaic Valley Water Commission. Even though the leak has been isolated, a boil water advisory remains for customers. Frustration is growing in Paterson and surrounding neighborhoods. Families are skeptical, saying that every day the city has claimed it is one step closer to resolving the problem, but there has been little improvement. "I am not saying they're not trying to do their best, but their best is not good enough still, because we are still suffering," Paterson resident Rita Pennant said. "Every day, it's two more days," Paterson resident Warren Ellis said. Officials are calling on residents to conserve water and not to open hydrants. Under the advisory, impacted residents should: Bottled water pick-up and the comfort station at John F. Kennedy High School will continue to stay open Tuesday.
