 For YHN News, I'm Elizabeth Kramer. Hot temperatures are in full force this summer, but even activities such as pool or beach time could quickly bring on an unwanted sunburn. Forecasters say the UV index will remain in the extreme range. With a UV index of 11 for the rest of the week, it means you can easily get a sunburn within 10 to 15 minutes if unprotected. Health experts are stressing the importance of wearing sunscreen when outdoors.
