Re: Raspberry Pi Storm Warning
My experience with depending on local sensors is that their warning is inadequate. When the barometer and temperature start falling through the floor, you can already see the wall of T-storms just a few miles away. Cloud state and wave patterns require some sort it of quantification too, and they can help when you are well away from land. The hurricane gives you a couple of days of warning with the unusual sea state and barometer drop, but a sailing vessel is too slow to avoid it completely.
Your proposed system would be more useful if it incorporated keyword recognition of text weather broadcasts from satellites or incorporates information from remote sensors. That will of course require an order of magnitude more work. Still, if you want to continue then you need the expertise of a meteorologist. I would suggest you do several things:
1. Review Dutton's Nautical Navigation
2. Review Chapman's Piloting and Seamanship
3. Talk to a local meteorologist. He may have both valuable insights and good references you can read.
