So, while I still haven't launched the weather generation app I still use my command line version for me campaign.

One thought occurred to me while determining the random encounters and weather, "How long do the conditions last?"

I ask this because the weather for the day in question is nasty.  During the course of the day they will encounter a great white shark and a pirate ship.

However, the weather would make the pirate encounter kinda not viable.

I was thinking that of having the storm last from midnight until 6am or so.

Any thoughts?
