What is the UV Index?

Some exposure to sunlight can be enjoyable; however, too much could be dangerous. Overexposure to the sun's ultraviolet (UV) 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 the sun's rays.

The UV Index provides an indicator of the expected risk of overexposure to the sun. The Index measures UV intensity levels on a scale of 1 to 11+, where low indicates a minimal risk of overexposure and 11+ means an extreme risk. The UV Index takes into account clouds and other local conditions that affect the amount of UV radiation reaching the ground.

By taking a few simple precautions, you can greatly reduce your risk of sun-related illnesses. To Be SunWise, consider the following steps:

  • Limit your time in the sun between 10 a.m. and 4 p.m.
  • Whenever possible, seek shade.
  • Use a broad spectrum sunscreen with an SPF of at least 15.
  • Wear a wide-brimmed hat and if possible, tightly woven, full-length clothing.
  • Wear UV-protective sunglasses.
  • Watch the daily UV Index.

While you should always take precautions against overexposure to the sun, please take special care to adopt the safeguards when the UV Index indicates levels of moderate or above.

 Pepper Ridge North Valley Random Weather Facts

The word "monsoon" comes from the Arabic "mausim" which means "a season" A common misuse of the term "monsoon" is to refer to INDIVIDUAL thunderstorms as "monsoons" (example - "The North Valley was pounded by monsoons this evening!"). The correct statement would be "The east valley was pounded by strong thunderstorms this evening!"

A MONSOON is a Seasonal wind shift that often brings a dramatic increase in moisture, and associated shower and thunderstorm activity, to the affected region. As the monsoon ends, and the winds shift again, the reverse occurs, with much drier air moving into the area.
