Early Warning System

Description
The Early Warning System is a Disaster Resource Structure. It's always better to evacuate people before a disaster, rather than trying to recover from the effects of one. As such, the Early Warning System is a very useful structure when it comes to preventing damage from natural disasters. These are especially useful in regions that are particularly prone to natural disasters, such as typhoons and volcanic eruptions. They are also a fairly small and inexpensive structure, though they're not necessarily the most efficient.

Gameplay
The Early Warning System serves as a Disaster structure. It is generally more useful than sandbags, but not as potent as other disaster structures. It's recommended that you don't rely on Early Warning Systems entirely, instead using them as a stepping stone to being completely prepared for a natural disaster.
