Summer Time Weather Warnings: What do they all mean?

Over the past several hours, you have been hearing about Heat Advisories, Air Quality Alerts, Red Flag Warnings, and so on. So just what do all of them mean?

A Red Flag Warning means that critical fire weather conditions are either occurring now or will shortly. In order to have a Red Flag Warning, the humidity needs to be low, normally 25% or less, strong winds of more than 15MPH, high temperatures, and dry vegetation. If we were not in a drought and had rain yesterday with low humidity today and strong winds, we most likely would not have a Red Flag Warning.

A Fire Weather Watch means that critical fire weather conditions are forecast to occur and that a Red Flag Warning might be necessary later.

An Excessive Heat Warning means that the heat index will be at least 105 for more than 3 hours per day for 2 consecutive days or if the heat index is greater than 115 for any period of time.

A Heat Advisory means that a period of hot weather is expected. High temperatures and high humidity will combine to create a situation in which heat illnesses are possible.

An Air Quaintly Alert means that ambient concentrations of ozone may reach or exceed the level of the National Ambient Air Quality Standards for Ozone.
