…EXCESSIVE HEAT WATCH REMAINS IN EFFECT FROM FRIDAY AFTERNOON THROUGH SATURDAY EVENING…

- Humid with low temperatures in the middle 70s Friday night.
- The combination of hot temperatures and high humidity will lead to an increased risk of heat-related stress and illness. The very young, the elderly, those without air conditioning, and those participating in strenuous outdoor activities will be the most susceptible.
- Car interiors can reach lethal temperatures in a matter of minutes.
An Excessive Heat Watch means that a prolonged period of hot temperatures is expected.
