Sunday's ultraviolet index level in the Los Angeles area will be 9, according to the National Weather Service.
- The reading indicates what the UV exposure is expected to be at noon, when the sun's rays are at their strongest.
- A reading of 0-2 indicates a minimal exposure level, and very fair skinned people could become sunburned in 30 minutes if not properly protected.
- A reading of 3-4 is considered a low exposure level, reducing the danger range for those with fair complexions to 15-20 minutes if not protected.
- A moderate exposure level of 5-6 indicates that a person with a fair complexion could be safe from sun burn for 10-12 minutes, unless protected.
- A high exposure level reading of 7-9 means that a person could be sunburned in 7-8 minutes.
- A very high exposure level reading of 10, or greater, means a fair skinned person could suffer a sunburn in about four minutes if not protected.
Ultraviolet radiation is blamed for a host of health problems, including skin cancer and cataracts.
