 There isn't really too much difference between an excessive heat warning and a heat advisory from what I could tell based on what the National Weather Service was passing along to us. But in terms of this excessive heat warning, the what is dangerously hot conditions with heat index values up to 110. Now, in terms of the heat, excuse me, in terms of the heat advisory, just getting a look of the National Weather Service has to say about that. They're saying here.
