First heat wave of 'torrid summer' to hit Eastern Canada next week
The first heat wave of Summer 2025 is about to hit Eastern Canada, with temperatures climbing to the mid-30s early next week. Add the humidity from a wet spring and it will feel even hotter. We'd better get used to it, as it is signalling 'a torrid summer ahead,' says David Phillips, senior climatologist with Environment and Climate Change Canada. 'We rarely go a year without a heat wave,' he says, 'but this will be the first one and people have to learn how to deal with it again.' The high pressure system will settle over southern and eastern Ontario as well as southern Quebec. It will edge into southeastern Manitoba on one side and western New Brunswick on the other. Contrasting this spate of heat with the renown 'polar vortex' of winter, Phillips refers to this phenomenon as a 'Bermuda High.' That's a semi-permanent, subtropical area of high pressure, which usually migrates east-west, back and forth across the North Atlantic, influencing weather patterns. Except this one is further west and further north than usual, says Phillips. 'It circulates southern air further north.' There's no doubt it will feel oppressive, says Phillips, adding that a heat dome squeezes air molecules, pressing them downward, creating heat from the friction. Moisture from a particularly wet spring will compound with the heat. There has been 30 to 40 per cent more precipitation than normal this year, he says. During the day the humidity may make it feel like 40 degrees Celsius or more. Another factor in the mix is the sunshine. Long summer days 'prevent the cool-off,' he says. At night, it will feel tropical, with temperatures above 20 C. The Maritimes won't get the extreme heat, but temperatures will rise, particularly in western New Brunswick. Western Canada has been experiencing heat already, with many hot, dry days (made worse by wildfire smoke), he says. But, he adds, in eastern Canada, people have been asking when the warmth is going to arrive. Normally, Eastern Canada would have several days in the 30s by now, says Phillips, but there were none in May and only one in June. Contrast that with Winnipeg, which he says has had nine or 10. 'In eastern Canada, people have felt left out, on the sidelines.' But now summer heat is arriving with a vengeance. It will be a three-day event with temperatures rising to the mid-30s in Toronto, Ottawa and Montreal, accompanied by nighttime temperatures in the 21-23 C range, with the humidex in the low to mid 40s. 'That's eight or nine degrees warmer than normal.' Ultimately, it seems we had better get used to this. All the weather-mapping models from Canada, the U.S. and Europe are predicting increasingly hot summers, says Phillips. 'This will be the first heat wave, but it's not going to be the last. We're going to see repetition throughout the summer.' He cautions that publicized high temperatures are measured in the shade. As a result, 'going out into the sun could add another seven to 10 degrees to the body. It's a lot of stress on the body. Too much.' It results in increased hospital admissions, he notes. 'People may not be dying in the streets but there is increased respiratory and cardiovascular distress.' The Canadian Red Cross urges people to stay indoors between 10 a.m. and 2 p.m., the hottest period of the day. Drink plenty of cool fluids — even if you're not thirsty. And avoid alcohol and caffeine, as both can result in dehydration. Check regularly with the children and seniors in your life to ensure they are drinking enough water. Finally, says the Red Cross, be aware of the following signs of heat illness: dizziness or fainting; nausea or vomiting; headache; rapid breathing or heartbeat; extreme thirst; dark yellow urine; muscle cramps, especially in arms, legs, or stomach.

First Montreal heat wave to hit this weekend bringing a phenomenon called a Bermuda High
Get ready: the first Montreal heat wave of summer 2025 is about to hit the city. With temperatures already reaching into the mid-30s, sweltering humidity from the recent wet weather will make it feel even hotter thanks to a humidex in the mid 40s. The summer 2025 forecast predicted a wet, humid summer in Montreal, and now we're in it. Starting on Sunday, Monday may see temperatures in Montreal rise up to 46 degrees celsius. The extreme heat event called a "Bermuda High" will last over three days. No better time to hit the beaches in and around Montreal, not to mention the outdoor pools, tree-lined parks and shady hiking areas. What is a Bermuda High? According to an Environment Canada meteorologist, this three-day heat event is called a Bermuda High, due to a semi-permanent subtropical area of high pressure that is further north than usual. It's time to check on your air conditioning: the southern air that is circulating further north will feel oppressive, and thanks to the abundant precipitation we've had over the past months (40 percent more than usual), the moisture will compound with the heat making it feel like 40 degrees celsius (or more). When will the heat wave hit Montreal? According to the Weather Network, things will really start to heat up on Sunday. Here's what to expect: Sunday, June 22: Expect a high of 30 degrees celsius that will feel like 40 degrees celsius Monday, June 23: The heat will reach 34 degrees celsius with a humidex soaring to 46 degrees celsius Tuesday, June 24 : The heat will hover around 33 degrees celsius and feel like 44 degrees celsius Why is Canada having heat waves? As greenhouse gas levels rise and drive global climate change, Canada is heating up at nearly twice the global average. With hotter springs and summers, we're seeing earlier snowmelt, more extreme heat waves, and ideal conditions for wildfires to spread.

'Incredible' Lightning Rainbow Strikes Florida
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. Striking images and video shared on social media captured the dramatic sight of lightning and rainbows lighting up the Florida sky. The Context The southwest Florida coast was forecast to see multiple rounds of slow-moving showers and thunderstorms by the National Weather Service (NWS) on Thursday. The agency warned that several inches of rainfall was possible, potentially leading to flash flooding in urban areas. A photo posted to social media captures the striking moment when lightning bolts flashed beneath a rainbow-streaked sky. A photo posted to social media captures the striking moment when lightning bolts flashed beneath a rainbow-streaked sky. Matt Devitt/X What To Know The images were posted Thursday by WINK News chief meteorologist Matt Devitt on X, formerly Twitter. "WOW! Incredible lightning and double rainbow combo this evening in Southwest Florida," Devitt said of the first image. "Amazing rainbow and lightning combo illuminating the sky this evening in Port Charlotte, Florida," read his post accompanying the second. Amazing rainbow and lightning combo illuminating the sky this evening in Port Charlotte, Florida! Credit: @WINKNews viewer Katie Johnson @spann @stormhour — Matt Devitt (@MattDevittWX) June 20, 2025 The NWS said it issued a flood advisory for the Naples metropolitan area after heavy rainfall developed. The service said this followed between 2 and 4 inches of rain. On Friday, the NWS forecast office in Miami said that more showers and thunderstorms were expected in the afternoon, primarily across interior and western South Florida. Much of the region would be hot and humid, with highs in the low 90s, it said. What People Are Saying NWS Miami, Thursday on X: "A pinned gulf breeze combined with ample atmospheric moisture will result in the potential of heavy rainfall & localized flooding along the Gulf coast of South Florida as slow moving showers and storms develop. Lightning & gusty winds are also possible with storms! "Over the last several weeks, the focus of afternoon showers and storms has been across southwestern Florida while mainly dry conditions have continued along the east coast metro. Why? Slightly stronger easterly flow thanks to the persistent influence of the Bermuda High." Meteorologist Matt Devitt, Thursday on X: "Classic, rainy season day in Southwest Florida with big rainfall amounts. 2 - 5" for many communities, leading to street flooding. More storms Friday too!" What Happens Next Elsewhere in the U.S., a heat wave is expected to bake swaths of the country from the Midwest to the East Coast starting Friday, with about one-third of the country set to contend with challenging temperatures, according to forecasters at AccuWeather. Meteorologist Adam Douty told Newsweek that this stretch of heat will intensify over the Plains and Midwest through the weekend, shifting to the East by early next week. While temperatures are expected to ease in the middle or late next week, highs will still stay above normal in many regions, he said.
