Do temperatures cool down to comfortable levels at night?🌙

Not always! Even after sunset, the heat can stick around!🥵

@KaylaMcDonaldwx explains why our overnight temperatures are staying dangerously warm and the important steps you can take to stay safe during extreme heat.☀️🌡️

Know the signs of heat illness so you can act quickly. Symptoms can include weakness, muscle cramps, nausea, sweating, and dizziness.

Get inside. Find shade. Hydrate. Get help if symptoms get worse. #HeatAwareness

When taking action to protect yourself from the heat, don’t forget about your furry friends!

• If the asphalt is too hot for your feet, it's too hot for their feet!
• Keep pets inside & hydrated!
• Never leave pets alone in a hot car!

Heat affects us all, but some of us are at greater risk. People react differently to heat based on their age, health, and living conditions. Check in on your neighbors, friends, and family on hot days to make sure they’re staying cool!

Everyone is at risk from the dangers of extreme heat, but groups that are most vulnerable include pregnant mothers, young children, the elderly, & those with health conditions. These groups should always have adequate hydration & a cool place to shelter and rest. #HeatAwareness

Happy that April hasn't had any 100°F so far! 😀🫣 Record-breaking March ... but the past 12 months are also the hottest 12 months on record for Arizona. 🥵

Reminder that Heat Index is not always a good tool for AZ!

Pay attention to the actual air temperature in AZ (right now the Phoenix air temperature is 90°F 🥵 ... and the Heat Index is 85°F 🤥). #azwx
