An exclamation point at end of every sentence...

...is meaningless.
And so is this "warning". It has been issued almost every day this summer for the Dallas/Fort Worth area:
"SEVERE WEATHER ALERT
...AIR POLLUTION WATCH LEVEL ORANGE...
AIR POLLUTION WATCH - LEVEL ORANGE - FOR DALLAS-FORT WORTH.

THE TEXAS COMMISSION ON ENVIRONMENTAL QUALITY (TCEQ) HAS ISSUED A LEVEL ORANGE AIR POLLUTION WATCH FOR THE DALLAS-FORT WORTH AREA FOR TUESDAY, SEPTEMBER 1, 2009.
ATMOSPHERIC CONDITIONS ARE EXPECTED TO BE FAVORABLE FOR PRODUCING HIGH LEVELS OF OZONE AIR POLLUTION IN THE DALLAS-FORT WORTH AREA ON TUESDAY. OZONE LEVELS COULD REACH THE LEVEL ORANGE UNHEALTHY FOR SENSITIVE GROUPS CATEGORY."
"ATMOSPHERIC CONDITIONS ARE EXPECTED TO BE FAVORABLE FOR PRODUCING..." So it's not even a real warning of an actual condition. Just a "might be" condition.
The upshot is, the TEXAS COMMISSION ON ENVIRONMENTAL QUALITY (TCEQ) has conditioned people to ignore "SEVERE WEATHER ALERTs". Now if we actually do have something we should be paying attention to, like, say, a tornado on the way, we'll never see the warning, because "SEVERE WEATHER ALERT" has completely lost any real meaning. Just like an exclamation point at the end of every sentence loses any meaning.

Haven't these people ever heard the story of the boy who cried wolf?
