WXSIM: forecast formatting script by: Saratoga-Weather.org. Greek translation: Τσιουκανάρας Αθανάσιος.

*Precipitation: Rain, snow, hail and all other forms of water falling from the sky. It is counted in mm. (Equivalent= l/m² - liters per square meter). Snow, is referred as water (melted snow = water equivalent in mm)

*UV Index: The UV index is an international standard measurement of how strong the ultraviolet (UV) radiation from the sun is at a particular place on a particular day. The Index predicts UV intensity levels on a scale of 1 to 11+, where 1 indicates a low risk of overexposure and 11+ signifies an extreme risk!

*Humidex:

*The humidex is an index used by Μeteorologists to describe how hot the weather feels to the average person, by combining the effect of heat and humidity. For example, if the temperature is 30° C and the calculated humidex is 40, that indicates that the humid heat feels approximately like a dry temperature of 40°.

*According to the Meteorological Service of Canada, a humidex of at least 30 causes "some discomfort", at least 40 causes "great discomfort" and above 45 is "dangerous." When the humidex hits 54, heat stroke is imminent.

*The index is widely used in weather reports during summer.
