Heat domes can lead to prolonged heatwaves, with daytime and nighttime temperatures remaining unusually high. This can create 'tropical nights,' where temperatures do not drop below 20°C, increasing the risk of heat stress. The extreme heat can also exacerbate drought conditions, fuel wildfires, and strain energy resources as people rely more on air conditioning. In some cases, heat domes can affect regions far from their center, spreading heatwaves across large areas.
