Current Conditions: 18°C with Smoke
At 6:00 AM today, the temperature was 18°C, with sunny skies observed at Big Trout Lake Airport. The humidity is high at 84%, and a light southwest breeze is blowing at 11 km/h. However, the seemingly calm start hides two serious weather advisories in effect: extreme heat and poor air quality due to wildfire smoke.
Heat Advisory: High Temperatures and Humidex
A heat event is gripping the region, with maximum temperatures expected to reach near 30°C today, accompanied by humidex values between 34 and 37. Overnight lows will remain near 18°C, offering only slight relief from the daytime heat. Extreme heat can pose significant health risks, particularly to vulnerable populations, so it’s crucial to stay hydrated and avoid strenuous outdoor activities.
Air Quality Alert: Smoke from Wildfires
Smoke from ongoing wildfires across northern Ontario is expected to cause poor air quality and reduced visibility throughout the day. The fine particles in the smoke are a significant health hazard, particularly for those with pre-existing health conditions, young children, and the elderly. If you must go outside, consider wearing a well-fitted N95 mask to reduce exposure to these harmful particles.
Today’s Forecast: Hot and Hazy
Expect mainly cloudy skies with local smoke reducing air quality. Winds will increase to 20 km/h, gusting up to 40 km/h by noon. The high temperature will reach 29°C, but with the humidex, it will feel more like 34°C. The UV index is moderate at 5, but with the haze, direct sun exposure may be less of a concern.
Tonight: Chance of Showers and Continued Smoke
Clouds will thicken tonight with a 40% chance of showers, possibly accompanied by a thunderstorm. Smoke will continue to affect air quality, and the wind will remain gusty before calming after midnight. The low will be 17°C.
Extended Forecast: Cooling Down with Showers
- Friday, August 23: Expect cloudy skies with a 70% chance of showers and a risk of thunderstorms in the morning. Smoke may persist early on, with winds becoming northwesterly at 30 km/h, gusting up to 50 km/h. The high will be cooler at 21°C, feeling like 25°C with the humidex.
- Saturday, August 24: Clearing skies will bring sunshine and a high of 26°C.
- Sunday, August 25: A return to warmer temperatures with a high of 29°C under sunny skies. Some cloudiness and a slight chance of showers will develop overnight.
Health Precautions: Stay indoors where possible, keep hydrated, and avoid outdoor activities during peak heat hours. Monitor air quality and health advisories closely, and check on vulnerable community members.
