The National Weather Service is forecasting an extended period of hot weather for Vermont starting Tuesday and continuing into the weekend. Heat index values are expected to reach the mid 90s in some locations later this week, with warm overnight temperatures. During the spring and early summer, when our bodies have not fully adjusted to warmer weather, heat illnesses are more common. People involved in outdoor activities and anyone without access to air conditioning are at especially high risk.
Vermont data indicates that emergency department visits for heat-related illnesses increase when temperatures reach the mid- to upper-80s, with impacts getting progressively worse as temperatures rise into the 90s. Sun exposure and humid conditions make the temperature feel even hotter.
Populations Most Affected
Individuals who are generally at higher risk for heat-related health impacts include: older adults; young children; outdoor workers and hobbyists; people who are pregnant; people who are overweight, have a chronic medical condition, mental illness, or disability; people using recreational drugs or alcohol; and people using certain prescription medications. Risk is further elevated for people that are unhoused but cannot access cooling facilities and for people that are housed but do not have air conditioning, especially if also living alone - dehydration and prolonged exposure to hot living conditions are major concerns for these populations.
Symptoms and first aid
Muscle cramps, heavy sweating, nausea, headache or light-headedness may all indicate a heat-related illness. Most heat-related illnesses can be treated with fluids and by resting in a cooler place. If symptoms persist or get worse, or someone you are with seems confused or loses consciousness, dial 9-1-1 and get immediate medical help. Learn more about symptoms and first aid.
Prevention guidance for communities
• Use Front Porch Forum or social media to raise awareness – examples are provided in our Hot Weather Media Toolkit.
• Be familiar with symptoms of heat-related illnesses and first aid responses.
• Offer safe and fun ways to stay cool, such as free or extended access to beaches and pools, providing hoses or misters, and offering free cold beverages.
• Consider opening a cooling center, which could be any air-conditioned, publicly accessible location (for example, a library or community center)
• Mobilize local care networks to use our Heat Guidance for Caregivers to check in on people at high risk for heat-related illnesses.
• For outdoor work, recreational activities, or other local events, ensure that organizes are prepared with water, cooling strategies, and event modification or cancellation plans.
• Hot weather can affect anyone – be aware of your own symptoms and look out for others.
• Use our local hot weather preparedness guidance and planning template to create a response plan for hot weather emergencies.
