UV Index Forecast

This map shows expected UV Index values. We all know that exposure to the sun generally feels good and produces Vitamin D for the skin; however, too much exposure to the sun's ultraviolet (UV) radiation can be dangerous as it can cause sunburn, skin cancer and cataracts. The UV Index represents the risk of overexposure to the sun on a scale of 1 to 11+, where 1 is low risk and 11+ is an extreme risk.

National Weather Alerts and Warnings

National Weather Alerts and Warnings. Note that Coordinated Universal Time (UTC) is a 24-hour time standard, is determined using atomic clocks, and expresses the mean solar time at the Earth's prime meridian (zero degrees longitude) located near Greenwich, England. Time zones around the world are expressed as positive or negative offsets from UTC (Eastern Time is -4 hours and Pacific Time is -7 hours). UTC is also often casually interchanged with Greenwich Mean Time (GMT).
