In order to help the people better understand the strength of UV light in their area on any given day, The National Weather Service and The Environmental Protection Agency (EPA) have developed The UV Index.
The UV Index gives people an idea of how strong the UV light is in their area on ascale from 1 to 11+. A higher number means greater risk of exposure to UV rays and a higher chance of sunburn and skin damage that could ultimately lead to skin cancer,
The UV Index is given daily for regions throughout the country. Further information about about the UV Index can be found on the EPA's website
