Heat and humidity will ramp up in parts of the province Thursday
After a brief respite, the heat and humidity are making a return to southwestern Ontario. Environment Canada has issued a heat warning for parts of the province, including Brantford, Six Nations, Flamborough and all of Haldimand County, as well as Milton, Halton Hills, Niagara Falls, Hamilton, Burlington and Toronto. Daytime temperatures are expected to hit 33 degrees Celsius on Thursday, but with the humidex, it will feel closer to 44. Thursday night, the mercury will only drop to 20 to 23 degrees Celsius. There also won't be any relief from the heat on Friday. Temperatures are expected to reach 30 degrees Celsius, feeling more like 40 with the humidex. Environment Canada said the hot conditions could also continue into the weekend. 'Staying cool and hydrated is key,' advised Alexandra Pinto, CTV Kitchener's Community Weather Host. 'Turn on air conditioning, move to a cooler area of your living space and plan outdoor activities during the coolest parts of the day. Also, never want to leave pets unattended in a vehicle.' Signs of heat illness Heat illness is a serious concern when the mercury rises, especially in older adults, infants, young children, pregnant people, those with physical or mental illnesses, people with mobility issues, those who work outside and the homeless community. Symptoms of heat exhaustion include: Headache Nausea or vomiting Dizziness or fainting Extreme thirst Dark urine and decreased urination Intense fatigue Confusion or lack of coordination Skin rash Muscle cramps Heavy sweating Rapid breathing and heartbeat Heat stroke, meanwhile, is considered a medical emergency. Those symptoms include: High body temperature Very hot, red skin Confusion or change in consciousness Dizziness or fainting If someone is experiencing heat stroke, experts advise moving them to a cool place, giving them water and placing ice packs on their body. Call 911 immediately. Beating the heat The key to avoiding heat illness is to plan ahead. Here are a few things to keep in mind: Know the weather forecast before going outside Modify your plans according to the weather Drink plenty of cool liquids, especially water, even before you feel thirsty Avoid drinks that are high in sugar, caffeine or alcohol Wear loose-fitting, light-coloured clothing made of breathable fabric Seek shade Avoid sun exposure if you can Take breaks as needed Avoid using your oven Take a cool shower or bath Take a break by spending a few hours in a cool place Close blinds and shades, Turn on air conditioning or use a fan Cooling centres The best way to get relief from the heat and humidity is to seek out a designated cooling centre. The Region of Waterloo has locations listed on their website. They include libraries, community centres, museums and regional offices. The map also includes a list of public swimming pools and splash pads. Protecting your pets Leaving pets inside a hot vehicle, even for a few minutes, could be dangerous. Dogs can experience heatstroke, which could lead to organ failure and, ultimately, death. Signs of an overheated pet include: Excessive panting Drooling Vomiting Collapsing Lethargy Tongue can appear red or hang out of their mouth If your pet is suffering from the heat, it's a good idea to gradually cool them down. Experts suggest using a cool blanket or towel that is wet. Avoid using ice. Owners should keep pets at home when the temperature climbs but if they need to go outside, keep them off the pavement as much as possible, only go for a short walk, or take them out in the morning or evening when it's cooler.

Record high temperatures set Wednesday in the Maritimes
The combination of heat and humidity made for a summer scorcher in the Maritimes Wednesday. Temperatures set some new records for July 16. High temperature records approached As of 4 p.m. the hottest temperature in Canada reported from Environment Canada monitored weather stations was at Bathurst, New Brunswick which reached 33.9 C. Humidex values across the Maritimes made it feel well into the high 30's and even near 40 C for many communities. Sites in all three Maritime provinces broke previous high temperature records. Record temperatures Preliminary and unofficial high temperature records set on Wednesday. Thursday thunderstorms Building heat and humidity increases the potential for thunderstorms. All you need is a trigger. A weak cold front passing across the Gaspe Peninsula into northern New Brunswick could be the trigger Thursday. The risk of thunderstorms will be highest in western and northern areas of New Brunswick beginning mid-to-late afternoon and extending into Thursday night. The risk of thunderstorms would typically diminish through the evening but because of the high heat and humidity I would extend the risk well into Thursday night. Thursday Thunderstorms A risk of thunderstorms for parts of western and northern New Brunswick on Thursday. Along with lightning the most likely hazards associated with any developing storms include downpours and flash flooding. There is also a moderate risk of strong local winds, with gusts that could approach 90 km/h in close vicinity to the thunderstorms. A more widespread chance of showers and thunderstorms is expected for the Maritimes on Friday.
