(3TV/CBS 5) -

The National Weather Service issued its first extreme heat warning of the season for this Sunday, May 6,  from 10 a.m. to 8 p.m.

Temperatures may reach between 105-109 degrees and residents are advised to plan ahead and be aware of this sudden increase in temperature.

“Since we went from relatively mild temperatures earlier this week to high temperatures this weekend, there is a real potential for people to experience heat-related illness this Sunday and even into next week. However, this can be easily avoided by taking simple steps: plan ahead by exercising during the cooler part of the day, drink plenty of water, and take breaks in air-conditioned locations to cool your body temperature,” said Dr. Rebecca Sunenshine, medical director for Maricopa County Department of Public Health.

Sunenshine pointed out that it’s also important to be aware of your body.

If you start experiencing muscle cramps, headaches, vomiting, rapid heart rate, confusion, or you are no longer sweating, these are all symptoms of heat-related illness and you should seek medical care immediately.
