Ultraviolet Levels at a High Exposure Rate Today & Tomorrow

Today and tomorrow's ultraviolet index level in Los Angeles is 7, which means a person could be sunburned in 7-8 minutes of exposure to the sun. Everyday, the National Weather Service's Climate Prediction Center releases the next day's UV levels and as we approach summer, these numbers have been climbing out of the low and moderate levels towards the high. "There are two prices to pay for overexposure to UV radiation: a severe sun burn following an intense short term overexposure, and the more serious skin cancers developing after long term overexposure," the Service explains. "Melanoma, the more deadly of the two types of skin cancer occurs when the patient has been subjected to several intense short term overexposures." If UV levels reach 10 or beyond, it could take four minutes to develop a sunburn.
