I have relatives who have never experienced snow, but the events in Atlanta have made them interested in snow storm preparation. The knowledge would be good for them.

Likewise, you don't have to live in drought territory to benefit from drought preparation. Chances are you know several people who live in drought territory, or you may be visiting drought territory.

A good rule of thumb for this topic is to focus prep around what is hot in the news. Using such a rule, the preparation may be too late in many circumstances. However, if you post winter prep at the beginning of summer for example, then only a few people will swing by your Facebook page to read those tips.
