Severe storms possible for southern Ontario, including Toronto
'Temperatures are expected to surge to the mid to even high 20s today across southern Ontario and the GTA as the area will be in the warm sector of a low-pressure system moving to the north of the area,' he explained.
'Humidex values will be approaching 30 as temperatures rise ahead of a cold front. There will also be gusty southwesterly winds as the above average temperatures settle in. That warmth and humidity will bring the potential for strong storms as a potent cold front slices through this sultry air mass today.'

'We are not ruling out an isolated tornado as the atmospheric ingredients will be conducive for it especially for parts of eastern Ontario.'
On Tuesday morning, he said it still uncertain how strong the storms will grow.
'The strength of the storms will also depend on how much sunshine areas see ahead of the front wish would lead to some additional atmospheric energy,' Hull explained.
He noted that the balmy weather Ontarians are seeing on Tuesday, will be gone as they make their way into the office on Wednesday.
'After the passage of the front temperatures will drop dramatically across the area … overnight into early Wednesday morning with values expected to be in the low single digits,' Hull offered.
'Calmer weather is expected Wednesday with clearing skies however with a daytime high near the low double digits cooler than average temperatures can be expected.'

Low water levels in Quebec rivers spur navigation warnings, watering bans
Boat pilots on the St. Lawrence River are being asked to take cautions because of low water levels that can cause navigation hazards. Kevin Lajoie, spokesman for the company that manages the St. Lawrence Seaway, says the corporation has restricted speeds in response to lower water levels on Lake St. Louis. Francis Fortin-Legault of Canadian Hydrographic Service says ship pilots should be subtracting about 10 centimetres from the available depth of water in the St. Lawrence River compared to what's indicated on maps of the waterway.

The Canadian Coast Guard put out a notice on Aug. 6, warning that buoys between Montreal and Trois-Rivières may be off position and unreliable due to levels that have fallen below the norms. Story continues below advertisement Montreal officials have also imposed restrictions on lawn watering and other water use in some boroughs west of downtown because of low levels in the Rivière des Prairies. They say the low levels create poor water quality and increase strain on water-treatment infrastructure. This report by The Canadian Press was first published Aug. 13, 2025.

Struggling with the heat? It's not just you as summer days above 30 C spike
Parts of Canada are starting to exit the latest crushing heat wave of the summer. And if this summer has felt particularly brutal for you, you're not alone — data shows multiple cities across Canada have already surpassed their normal number of days above 30 C. Halifax, Toronto and Montreal are among those that have seen more days above that threshold than they normally do, while roughly 51 daily heat records were broken across the country on Monday as temperatures in many regions soared into the mid-30s C, according to Environment Canada. Global News chief meteorologist Anthony Farnell says multiple heat waves and long-lasting ones is becoming a new normal. 'We've always had heat waves, that's nothing new; it's the duration,' he said. 'The fact that it's not just a two- to four-day stretch of hot weather, it is lasting longer than typical and that leads to more drought and it can sometimes lead to extremes like we're seeing now across the East.' Story continues below advertisement In Halifax, for example, there have been seven days so far this summer where the temperature has surpassed 30 C. It might not seem like much, but Farnell said it's higher than the five seen last year, and above the normal number of days above 30 C, which is about three. Ontario and Quebec have seen many more. 2:15 Health Matters: Heat wave continues in Eastern Canada As of Tuesday, Toronto has seen 22 days since June 1 where the temperature was above 30 C.

Sign up for breaking National newsletter Sign Up By providing your email address, you have read and agree to Global News' Terms and Conditions and Privacy Policy The normal number for the city is about 17, but last year it only saw 10 days. In an average summer, Montreal would normally see about 11 days above 30 C and last year it saw 12, but this year, Farnell said the city has already had 20 days. Story continues below advertisement 'We still have several weeks of warmth left, so it just really is a variable that alternates year to year, but it's above normal this year in Toronto and for many cities across the country,' he said. In Ontario, 10 heat records were broken or tied in places like Algonquin Park, Goderich, Parry Sound and Bancroft. The Maritimes also saw records broken, with Mirimichi, N.B., breaking a temperature record that has stood for more than 150 years by hitting 37.6 C on Monday. La Scie, N.L., set a new monthly high of 31.5 C, breaking the 31 C record set on Aug. 7, 1990. All that heat has also led to drought conditions in many locations. Agriculture Canada reported that fully 71 per cent of the country was classified as abnormally dry or being in a moderate to extreme drought by the end of July. St. John's, N.L., typically sees a normal precipitation of 230 millimetres, but since June 1 has only had about 101 mm, while downtown Toronto has seen 80 mm instead of the normal 185 mm. Toronto's rain is also a large decrease from the higher amount of rain seen last year, when it hit about 340 mm. Farnell said these cities, as well as Halifax, are running under 50 per cent of their normal rainfall since the start of summer, which, coupled with drought conditions, leads to a high risk of fires. Story continues below advertisement The latest figures posted by the Canadian Interagency Forest Fire Centre suggest wildfires have torn through 72,000 square kilometres, making it the second-worst season on record. Yet not every city has faced high heat and low rain. Farnell noted that Calgary has actually seen higher amounts of rainfall, with 314 mm having fallen since June 1, compared with its normal 193 mm. The city also has seen a slightly higher number than the normal five days of 30-plus temperatures with eight so far, but it's still below the 15 seen last year. Environment Canada told The Canadian Press in an interview that British Columbia and the Prairies are expected to see some rainfall this week as the heat wave facing parts of the country lifts, while some rain will also fall on the Maritimes toward the end of the week. Farnell says that while rain is welcome, it will need to be more than a short shower for there to be an impact. 'Sometimes you can get a thunderstorm in a quick 20 to 30 millimetres, but it happens in less than an hour and most of that just runs off and it doesn't get absorbed into the ground,' Farnell said. More heat could be coming as summer still has a few weeks left, but Farnell says the weather pattern facing Canada is 'turning cooler,' meaning wetter weather could soon be on the way.

'We got out in about fifteen minutes.' 1:27 Out-of-control Mount Underwood wildfire closes roads, cuts off power to Bamfield The road between Port Alberni and Bamfield remains closed due to the fire. More than 500 BC Hydro customers in Bamfield and the surrounding First Nations villages also remain without power. 'I said to someone earlier today, I personally can't look out a window without seeing the plumes of smoke and I think many people are in that same situation,' Port Alberni Mayor Sharie Minions said. 'And I know that that comes with extreme discomfort.'
