Saturday storms produced three tornadoes near Goderich, tornado researchers confirm

3 eyewitness videos show storm, suspected tornado in southwestern Ontario 1 day ago Duration 1:29 A strong supercell thunderstorm that crossed parts of southwestern Ontario on Saturday produced three separate tornadoes in the span of an hour, researchers with Western University's Northern Tornadoes Project confirmed Monday. All three tornadoes spawned between 6:30 p.m. and 7:30 p.m. on Saturday near Goderich as the storm system came ashore from Lake Huron. The first tornado occurred on the lake as a waterspout, about 14 kilometres northwest of Bayfield, according to coordinates provided by Northern Tornadoes Project (NTP). "Then it weakened a bit, and once it got on shore, it started producing a tornado again at Porter's Hill ... then it intensified again and produced another tornado further inland near Harlock," said David Sills, NTP's director. The three tornadoes produced minor damage on land, and have been classified as EF-0 in strength, the weakest rating on the enhanced Fujita scale. No injuries have been reported, Sills said. NTP conducted a ground and drone survey of the area on Sunday to document damage and to chart the paths of the two land tornadoes. "The one bit of structural damage we know about from the tornado near Porter's Hill was a structure that had its roof peeled back," along Sharpes Creek Line, Sills said. Damage to a coverall building and to trees was also reported. That twister had wind speeds of at least 124 km/h, and travelled 6.24 kilometres with a maximum path width of 190 metres, he said. "The other tornado that hit Harlock was really impressive visually, but only produced weak damage — basically 90 km/h, a few tree branches broken," he said. It travelled nearly 4.7 kilometres with a maximum path width of 330 metres. CBC News spoke with several residents on Sunday who recalled there being a calm before the storm's quick arrival. "We sat down to have dinner, and all of a sudden my mom was like, 'You need to get to your safe place,'" said Deobrah Caira who lives near Blyth in the area where the third tornado touched down. "I said, 'It's all clear and sunny outside.' Sure enough, I looked outside, and I saw this cloud formation rotating, coming toward us." A short time later, the family took cover in the home's centre hallway as the tornado ripped by their property. "The doors were shaking on their hinges. The whole house was shaking," Caira said. The passing tornado dissipated through a field behind the family's property, but not before it damaged a 150-year-old tree and tossed Caira's roadside vegetable stand down the driveway. "There was a bit of confusion ... because there was a large marine tornado warning issued as the tornado over the lake was happening. I think quite a few people on shore got that warning," Sills said. "But as the tornado moved onshore, there didn't appear to be a tornado warning issued then. When it came on shore, I don't think there was any warning or watch in effect, at that point." The three tornadoes followed an EF-1 rated downburst that occurred in Mitchell on Thursday which damaged several barns, power pole, trees, and crops.

On This Date: America's Record-Largest Hail Fell In South Dakota

Sometimes you need a little serendipity to set a new all-time weather record. On July 23, 2010, 15 years ago today, a supercell thunderstorm spawned a brief tornado and an 85-mph wind gust near Vivian, South Dakota, about 30 miles south of the state capital, Pierre. But it was the hail this supercell produced that etched this storm into U.S. history. One resident of Vivian saved several of the giant hailstones in a freezer after they pelted his property. Meteorologists from the National Weather Service in Aberdeen, South Dakota, later visited the Vivian resident and measured the largest of these stones to be a whopping 8 inches in diameter and 1.9375 pounds, both new U.S. records, topping the previous record from Sept. 3, 1970, in Coffeyville, Kansas. (WATCH: Flash Flood Floats New Mexico Business) It's hard for a single photo to illustrate how mammoth this hail was. The Vivian hailstone was almost as wide as a typical ball your child might use on the playground and roughly as heavy as a hammer. Now picture those stones falling at speeds over 100 mph, and you might imagine the damage they caused. The hail left large divots in grass and punched a hole through the deck of the Vivian home. And because the severe thunderstorm knocked out power at the home, the record hailstone melted somewhat between when it was first found and when the NWS meteorologists measured it. The Vivian hailstone is also the heaviest on record in the Western Hemisphere, according to the World Meteorological Organization. The heaviest hailstone anywhere on Earth weighed 2.25 pounds in the Gopalganj district of Bangladesh on April 14, 1986.

PHOTOS: Supercell hits Calgary area with hail, torrential rains

A strong supercell thunderstorm blew into the Calgary area on Sunday evening, bringing a dose of high winds, large hail, and heavy rains to the region. A favourable setup for severe weather on Sunday evening sparked numerous potent thunderstorms across southern Alberta. Environment and Climate Change Canada (ECCC) issued a severe thunderstorm warning ahead of the storm's arrival, alerting residents of the potential for up to golf ball size hail and very strong wind gusts. There were no immediate reports of damage early Sunday evening. Check out some of the visuals of the storm and its hail, below. #yyc #yycstorm — Liza (@blabbit000) July 14, 2025 Kind of not loving what's above me right now SW Airdrie 7:55 pm#abstorm #YYCWeather #ABweather — Heather 🐾 (@hlmanser) July 14, 2025 It's #yyc #abstorm #calgary #stampede #hail — Denise Henwood (@DeniseHenwood) July 14, 2025 NW Calgary hail aftermath. #abstorm — Mark Lehman (@Mlehman99) July 14, 2025 Over toonie sized hail in Nw Calgary.

Supercell storm blows through Ithaca and downs trees, electrical wires

The National Weather Service in Binghamton tracked a "significant supercell," or a strong thunderstorm with a heavy updraft, from Penn Yan to New Jersey, causing widespread damage on July 3 and 4. Meteorologist Adam Gill confirmed a tornado warning near Ithaca on July 3, but no evidence of a tornado touchdown. The storm produced strong winds and extensive damage, including downed trees and wires, Gill said during a July 7 interview. "That storm produced what's called a rear flank downdraft, and in that rear flank downdraft, there is frequently 70 to 90 mile an hour winds, so there's a pretty broad swath of damage, basically extending some the Ithaca all the way Southeast through Binghamton and then down into Northeast Pennsylvania," he said. Prior reports and communications sent to The Ithaca Journal from residents in Newfield, Enfield and Danby suggest localized damage and outages. A video by Ithaca-area photographer Cindy Massicci, which has since been featured in ABC World News, showed the world a view of the skies in the Ithaca area on the evening of July 3. More than 1,500 people in Ithaca were without power for the night of July 3 as upwards of 50 electrical poles were repaired throughout the region, according to NYSEG statements. This article originally appeared on Ithaca Journal: July 3 Ithaca storm was a 'significant supercell,' meteorologists say
