Heat advisory

Weather statement indicating high heat index values

Weather statement indicating high heat index values

A heat advisory is a notice issued by the National Weather Service of the United States. Local offices often have their own criteria. High values of the heat index are caused by temperatures being significantly above normal, coupled with high humidities. Such combined high levels can pose a threat to human life through conditions such as heat stroke.

Example

The following is an example of a heat advisory issued by the National Weather Service office in Pittsburgh, Pennsylvania.
