You'll want to stay updated on the weather alerts in your area as conditions can change quickly when severe weather hits.
Thursday: Ample thunderstorm energy leads to strong storms, tornado risk
Forecasters are keeping a close eye on Thursday, with a low-pressure system and strong cold front expected to bring more severe weather to eastern Ontario and southern Quebec. The system will track over the Great Lakes Thursday morning and continue eastward through the day.
Ample thunderstorm energy, fuelled by several days of 30°C heat and high humidity, could lead to strong thunderstorms with torrential downpours. Between 50-100 mm of heavy rainfall is possible under storms, increasing the risk of localized flooding.
DON'T MISS:
Non-severe thunderstorms are expected to move through the Greater Toronto Area (GTA) before peak afternoon energy develops.
Thunderstorm energy will be abundant by the afternoon hours, with ample moisture, and signs of notable shear will result in strong and severe storm clusters over the Ottawa Valley and southern Quebec.
Multiple rounds of strong to severe storms are likely for Quebec City.
-4 p.m. will be the highest risk for severe weather in Ottawa with the cold front.
6 p.m. for Montreal.
11 a.m. to 9 p.m. for Quebec City.
The Ottawa and St. Lawrence valleys will be concerned with flooding potential, while tornado ingredients may be present over the Laurentians and areas near the Quebec-New Brunswick border, although confidence is still low and conditions are being closely monitored by forecasters.
The active weather will be followed by a welcome cooldown, offering relief from the heat.

Fourteen people die in South Korea after torrential rain causes landslides and flooding
Five days of torrential rain in South Korea has left at least 14 people dead and 12 more missing. A landside engulfed houses and flooding swept away vehicles in the resort town of Gapyeong, northeast of capital Seoul, on Sunday. One person was killed after their house collapsed and another was found dead after being swept away by a swollen stream, while six people remain missing in the town and the southern city of Gwangju. The Interior and Safety Ministry said eight people were killed and six others reported missing in the southern town of Sancheong on Saturday after heavy downpours caused landslides, house collapses and flash floods. Earlier in the week, three people were found dead in a submerged car, and a person was also killed when their car was buried by soil and concrete after a retaining wall of an overpass collapsed in Osan, just south of Seoul. Southern regions have been hit by up to about 600-800mm (24-31 inches) of rain since the downpours began n Wednesday. About 3,840 people remained evacuated from their homes by Sunday morning. The heavy rainfall moved north overnight and alerts have been lifted throughout the country, ministry officials said.

South Korea rain death toll rises to 14: government
At least two people were killed during heavy downpours in South Korea Sunday, the interior ministry said, bringing the death toll to 14 from torrential rains this week. The toll could rise, with 12 people still unaccounted for after five days of heavy rain. Close to 170 millimetres (6.7 inches) of rain hit Gapyeong county in Gyeonggi province — 70 kilometres (40 miles) east of Seoul -- early Sunday, leaving at least two dead and four missing. A woman in her 70s was killed when her house collapsed in a landslide while body of a man in his 40s was found near a bridge after he drowned, Yonhap news agency reported. The total number of deaths from the five-day deluge now stands at at least 14, according to official data. Most of the deaths occurred in the southern county of Sancheong, which has seen nearly 800 millimetres of rain since Wednesday. Two bodies were found there early Sunday during search and rescue operations, raising the number of deaths in the rural county of 33,000 to eight, with six still missing. South Korea typically experiences monsoon rains in July and is usually well-prepared. But this week, the country's southern regions were hit by especially intense downpours, with some of the heaviest hourly rainfall on record, official weather data showed. Scientists say climate change has made extreme weather events more frequent and intense around the world. In 2022, South Korea endured record-breaking rains and flooding, which killed at least 11 people. kjk/mtp

3 people are still missing from deadly July 4 floods in Texas county, down from nearly 100
KERRVILLE, Texas (AP) — Officials in a Texas hill country community pummeled by deadly flooding July 4 said Saturday that just three people remain missing, down from nearly 100, after people who had previously been reported missing have since been accounted for. The reduction in the number of people on the missing list came as the search for victims entered its third week. It was a significant drop from the more than 160 people officials previously said were unaccounted for in Kerr County alone. 'This remarkable progress reflects countless hours of coordinated search and rescue operations, careful investigative work, and an unwavering commitment to bringing clarity and hope to families during an unimaginably difficult time,' Kerrville City Manager Dalton Rice in a statement. The death toll in Kerr County, 107, held steady for much of this week even as the intensive search continued. The Flash floods killed at least 135 people in Texas over the holiday weekend, with most deaths along the Guadalupe River in Kerr County, about 60 miles (100 kilometers) northwest of San Antonio. Just before daybreak on July 4, the destructive, fast-moving waters rose 26 feet (8 meters) on the Guadalupe, washing away homes and vehicles. The floods laid waste to the Hill Country, a popular tourist destination where campers seek out spots along the river amid the rolling landscape. It is naturally prone to flash flooding because its dry, dirt-packed soil cannot soak up heavy rain. Vacation cabins, youth camps campgrounds fill the riverbanks and hills of Kerr County, including Camp Mystic, a century-old Christian summer camp for girls. Located in a low-lying area of a region known as 'flash flood alley,' Camp Mystic lost at least 27 campers and counselors. The flooding was far more severe than the 100-year event envisioned by the Federal Emergency Management Agency, experts said, and it moved so quickly in the middle of the night that it caught many off guard in a county that lacked a warning system. In Kerrville, about 100 miles (160 kilometers) west of Austin, local officials have come under scrutiny over whether residents were adequately warned about the rising waters. President Donald Trump and Texas Gov. Greg Abbott have pushed back aggressively against questions about how well local authorities responded to forecasts of heavy rain and the first reports of flash flooding. Crews have been searching for victims using helicopters, boats and drones. Earlier efforts were hampered by rain forecasts, leading some crews to hold off or stop because of worries about more flooding.
