Young children and pets are especially vulnerable to extreme heat.

Never leave children or animals unattended in a parked vehicle, as interior temperatures can rise to life-threatening levels within minutes.

If you must work or exercise outdoors, wear lightweight, light-colored clothing, take frequent breaks, and know the signs of heat exhaustion and heat stroke.

Symptoms such as dizziness, heavy sweating, weakness, nausea, or confusion should be taken seriously. Seek medical attention immediately if someone shows signs of heat stroke, including loss of consciousness or a high body temperature.

The dangerous heat is expected to continue through this evening before conditions gradually improve. Stay weather aware, limit outdoor activities when possible, and continue monitoring the latest forecasts and advisories throughout the day.
