Heat exposure can lead to severe or fatal results, particularly in older people, infants and young children and those with chronic illnesses.

Heat waves begin when high pressure in the atmosphere moves in and pushes warm air toward the ground. That air warms up further as it is compressed, and we begin to feel a lot hotter.

As the ground warms, it loses moisture, which makes it easier to heat even more. As that trapped heat continues to warm, the system acts like a lid on a pot called “heat dome.”
