The National Weather Service is predicting an Ultra Violet Index of 11, what is considered an extreme exposure level, for noon tomorrow.

The UV Index measures ultra violet radiation exposure on a scale of 0-15. Readings over 10 are considered "very serious" or "extreme."
Under such conditions, people are advised to use SPF 15 skin protection, protective clothing, and sun glasses and to avoid being in the sun between 10am to 4pm.
