Wildfire smoke timeline. What to expect:
Meteorologists report that the smoke will retreat northeast this afternoon as winds shift. A few showers and thunderstorms may develop, but widespread soaking rain is unlikely.
All indications point to smoke returning by tomorrow evening. It is uncertain how thick the smoke will be, but air quality issues are expected to resurface, with the possibility of sludge from the mix of smoke and water.
With high temperatures expected in the area, Cook County Public Health is reminding residents and visitors to take steps to stay cool and hydrated, and to know where they can go for relief from the heat.
Cook County may be known for its cooler weather, but unusually hot temperatures for our area can still pose health risks. Many homes in our community also lack air conditioning.
If your home gets too warm, consider spending time in a cooler, well-ventilated, or air-conditioned public space. Locations in Grand Marais where people can go to stay cool include:
- Grand Marais Public Library, 104 2nd Avenue West
- Cook County YMCA, 105 5th Street. Access may depend on membership or facility policies.
- The Grand Marias Hub, 10 N Broadway Ave, Grand Marais, MN 55604
Other cool, well-ventilated, or air-conditioned public buildings and businesses that are open to the public. Residents should check current hours and access requirements before visiting.
During periods of high heat:
- Drink plenty of water, even if you do not feel thirsty.
- Limit strenuous outdoor activity during the hottest part of the day.
- Take frequent breaks in the shade or a cooler indoor space.
- Wear lightweight, loose-fitting clothing.
- Check on family members, friends, and neighbors who may be more affected by the heat.
- Never leave children or pets in a parked vehicle.
- Pay attention to local weather forecasts, heat advisories, and air quality alerts.
Heat exhaustion can cause heavy sweating, headache, nausea, dizziness, weakness, and thirst. Move to a cooler location, drink fluids, and cool the body if symptoms develop.
Heat stroke is a medical emergency. Signs may include confusion, slurred speech, loss of consciousness, seizures, or a very high body temperature. If you think someone may be experiencing heat stroke, call 911 immediately.
Cook County Public Health will continue to monitor conditions and will share additional information if a formal cooling shelter is opened.
