Heat warning vs. watch vs. advisory
Excessive heat poses a significant risk to people’s health, including heat stroke and heat exhaustion, which can result in death. Excessive heat generally means unusually hot temperatures, possibly combined with oppressive humidity, that persists for two or more days.
An Excessive Heat Watch is typically issued two to five days ahead of possible dangerous heat conditions. Certainty regarding the development and timing of the event is lower than a warning.
An Excessive Heat Warning, sometimes preceded by an Excessive Heat Watch, is typically issued within one to three days of the onset of extremely dangerous heat conditions and remains in effect until the extreme danger subsides. Certainty is high that the event will occur
A Heat Advisory is typically issued within one to three days of the onset of dangerous heat and remains in effect until the danger subsides. These conditions pose a lesser, but still dangerous, risk to communities. Certainty is high that conditions will occur.
