Dangerous US Heat Wave Puts Millions at Risk This Week
Dangerous US Heat Wave Puts Millions at Risk An intense heat dome is spreading across large parts of the United States this week, bringing dangerously high temperatures and humidity that could put more than 130 million people at risk. The latest forecasts from the National Weather Service (NWS) show the mercury will soar well above seasonal averages and the heat index or “feels like” temperature could top out at over 110°F (43°C) in several areas. Health officials are telling people to stay inside during the hottest part of the afternoon, stay hydrated and to check on elderly relatives, children and people without air conditioning.
This weather pattern is being driven by a strong high pressure system often referred to as a heat dome. This weather pattern traps hot air near the surface, allowing temperatures to climb day after day. The risk of heat exhaustion, heat stroke and other heat illnesses is up with prolonged heat in the forecast for major cities across the Midwest, Great Lakes, Mid Atlantic, North-east and parts of the South. Travellers are also being warned to brace for extreme weather conditions during the Fourth of July travel period.

Why the Heat Wave Is Becoming More Severe
Meteorologists say a powerful heat dome is preventing cooler air and storm systems from reaching areas affected by the current dangerous US heat wave, worsening it. When the humidity is higher, the heat index is higher and it feels hotter than the actual temperature. Unlike the occasional hot weather, which is just for a few days, this will be for several days and will put more strain on power grids, transportation systems, agriculture and public health services.
Medical officials warn that extreme heat can affect healthy adults if they are exposed for long enough. If temperatures remain high overnight, heat-related illnesses can develop more rapidly because the body has less opportunity to recover. Concrete buildings and paved roads create urban heat islands that can raise the temperatures of cities.
Important Instructions During the Dangerous US Heat Wave
- Even if you don’t feel thirsty, drink a lot of water.
- Stay inside during the hottest part of the day.
- Wear light-colored, lightweight clothing.
- Never leave children or pets in a parked vehicle.

The hottest temperatures in the current forecast are for parts of the Midwest, Great Lakes, Ohio Valley, Mississippi Valley, Mid Atlantic, North-east and Southern states. Cities such as Chicago, New York, Philadelphia, Washington, Detroit, St. Louis, Dallas and Memphis could see temperatures near or above 100 degrees with humidity making it feel even hotter.
Dry conditions in several areas are also driving heightened wildfire risks in western states. Officials are encouraging people to adhere to local fire restrictions and not do anything that could inadvertently spark wildfires.
