Extreme heat wave expected to peak with record-breaking Monday

Monday is forecast to be the hottest day of an extreme, dangerous heat wave for the Ottawa-Gatineau area, with temperatures in the mid-30s and humidity making it feel like the mid-40s. Heat warnings remain Monday and Tuesday for all of eastern Ontario and western Quebec. The forecasted highs for some major local hubs are: 36 C in Ottawa and Gatineau, with humidity peaking at 44. 34 C in Maniwaki, with humidity peaking at 44. 34 C in Pembroke, with humidity peaking at 42. 33 C in Trenton, with humidity peaking at 44. 32 C in Kingston, with humidity peaking at 43. Many of those temperatures would set daily heat records. Ottawa topped out just under 30 C Sunday, with humidity making it feel like 37 at its hottest in late afternoon. It felt like 36 with the humidity there by 8 a.m. Monday. WATCH | Safety tips in extreme heat: Health agencies say people are likely going to have to change their routines to stay safe in this dangerous heat. Health Canada recommends staying cool and staying hydrated when extreme heat hits. That can mean everything from drinking lots of water and planning outdoor activities for cooler times, to preparing meals that don't require ovens and keeping nearby air-conditioned spaces in mind if needed. This is true for yourself and for vulnerable people you know. Watch for signs of heat exhaustion — like a headache, dizziness or a rapid heartbeat — and get to a cool place where you can drink water. Heat stroke, which includes confusion and very hot or red skin, is a medical emergency requiring a 911 call. More resources may be available through your municipality. Ottawa, for example, has a map of public and other places to cool off. New Ottawa fire ban Some changes are also being made in the name of safety, such as the Western Québec School Board cancelling classes Monday. Ottawa is now under an open air fire ban. Research shows heat waves are becoming increasingly extreme as the climate warms. Environment Canada has started analyzing weather data and climate model simulations to compare how heat waves have changed between today's climate and the cooler pre-industrial one.

Extreme heat safety tips as dangerous temperatures head to East Coast

Life-threatening heat is enveloping the eastern U.S., with some cities bracing for what could be their highest temperatures in over a decade. On Monday, the heat index -- what the temperature feels like with humidity -- is expected to skyrocket to 98 degrees in New York City; 107 degrees in Philadelphia; 109 degrees in Richmond, Virginia; and 106 in Raleigh, North Carolina, and Charleston, West Virginia. Temperatures are forecast to be slightly higher on Tuesday. Doctors recommend taking excessive heat warnings seriously. Over 700 people die from heat-related illnesses every year, according to the Centers for Disease Control and Prevention, and extreme heat is considered the deadliest weather-related hazard in the U.S., according to the Fifth National Climate Assessment. A heat wave is a continuous period of abnormally hot weather, generally lasting over two days, according to the National Weather Service. However, the definition of a heat wave varies by region. MORE: How to conserve energy during a heat wave In the Midwest and the Northeast, a heat wave is considered three or more days in a row of temperatures of at least 90 degrees. But in Phoenix, for example, temperatures are regularly well above 90 degrees and into the triple digits without it being from a heat wave. So a heat wave is relative to the local average temperature and may require temperatures to be significantly above normal for several days, according to the NWS. Here are tips to stay safe from the heat from the CDC: Take precautions to prevent sunburn, which can make you dehydrated and affect your ability to cool down. Use sunscreen that's SPF 15 or higher 30 minutes before going outside. Sunscreens that say "broad spectrum" or "UVA/UVB protection" are best. Drink extra fluids, and don't wait until you're thirsty. Avoid very sugary drinks and alcohol, which can cause your body to lose more fluid, and be wary of extra-cold drinks that may cause stomach cramps. Avoiding hot and heavy meals also can reduce your body's overall temperature. Cut down on exercise during heat waves and rest often and in shady areas. Try to limit your time outside to when it is cooler, like in the early morning and evening. Never leave children in a parked car -- even if windows are cracked open. MORE: Hot car safety tips Anyone can suffer from heat-related illness at any time, but these people are at greater risk: -- Babies and young children -- Overweight people -- Those 65 years old or older -- People who overexert during work or exercise -- Those who suffer from heart disease or high blood pressure and those who take certain medications, including for depression, insomnia or poor circulation Symptoms of heat stroke include: -- Body temperature of 103 degrees or higher -- Hot, red, dry or damp skin -- Fast, strong pulse -- Headache -- Dizziness -- Nausea -- Confusion -- Passing out -- No longer sweating Symptoms of heat exhaustion include: -- Heavy sweating -- Cold, pale, clammy skin -- Fast, weak pulse -- Nausea or vomiting -- Muscle cramps -- Feeling tired or weak -- Headache -- Passing out If someone shows symptoms of heat stroke or heat exhaustion, call 911, move them somewhere cooler and use towels to cool down their body. Don't forget about your furry friends! Here are some tips from the American Society for the Prevention of Cruelty to Animals for how to keep your pets safe in the heat: provide plenty of fresh water so they don't get dehydrated; don't over-exercise pets; never leave pets alone in a parked car; and watch for symptoms of overheating, which include excessive panting, difficulty breathing, increased heart and respiratory rate and drooling. Animals with flat faces, like pugs, can't pant as well and are more at risk of heat stroke. These pets, as well as older and overweight pets, should be kept inside as much as possible.
