What is the UV Index?The UV Index provides a daily
forecast of the expected risk of overexposure to the sun. The Index
predicts UV intensity levels on a scale of 0 to 11+, where 0
indicates a minimal risk of overexposure and 11+ means a very high
risk. Some exposure to sunlight can be enjoyable; however, too much
could be dangerous. Overexposure to the ultraviolet (UV) rays of
the sun radiation can cause immediate effects, such as sunburn, and
long-term problems, such as skin cancer and cataracts. The UV
Index, which was developed by the National Weather Service and the
U.S. Environmental Protection Agency (EPA), provides important
information to help you plan your outdoor activities to prevent
overexposure to sun rays.
