What a heat advisory means
A heat advisory is issued when the heat index, which combines temperature and humidity, is expected to reach levels that can cause heat exhaustion or heat stroke. Thresholds vary across the country because people adapt to their local climate: offices in the Gulf Coast use higher values than those in the Northeast or Pacific Northwest.
