Fire!

While not intrinsically wrong, there's really no need for an exclamation point here.

Since the Burbank Fire Department clearly wants to impart some urgency, wouldn't they be better off putting the exclamation point after "HIGH"? I mean, on the "FIRE DANGER MODERATE TODAY!" days - which are, admittedly, few and far between in Los Angeles County - it seems like this sign would be left with some misguided enthusiasm.
