LOS ANGELES – The ultraviolet index level in the greater Los Angeles area is expected to be a ’10’ on Tuesday, meaning “very high,” 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.

Under very high UV conditions, it’s recommended that people minimize their sun exposure between 10 a.m. and 4 p.m. If outdoors, you should seek shade and wear sun-protective clothing, a wide-brimmed hat, and UV-blocking sunglasses.

Those who will be outdoors should apply broadspectrum SPF 30+ sunscreen every two hours, and after swimming or sweating. Bright surfaces, such as sand and water can increase UV exposure.

A very high exposure level reading of 10, or greater, means a fairskinned person could suffer a sunburn in about four minutes if not protected.
