Monster alert 

Your phone doesnt send you one when a monster is near.

The monster's ankle monitor didnt set off a monster alert in their area.

Monster alert 

One of two alerts the sim city folks that send alerts to your phone about weather and disasters don't send you, the other being alerts about alien invasions.

Had people gotten the monster alert sooner, they might have had time to prepare instead of react.
