“The dealership is holding a sales event over Memorial Day weekend.”
“Yesterday’s rain event in Oklahoma caused widespread flooding. However, tomorrow should bring only minimal shower activity.”
“The defense attorney cited acts of an inflammatory nature.”
“The drought condition has many farmers concerned.”
“The police responded to an emergency situation at the rest stop.”
Events, situations, conditions, and activities are almost always fillers used to make something sound more impressive (but not very effectively). Whenever you use one of those words, see if you can’t reword your sentence more concisely:
That dealership is holding a sale. The report was about yesterday’s rain in Oklahoma. The prospect for tomorrow is merely showers. Those farmers are worried about the drought, and the police officers responded to an emergency.
