Where I live in West Central Florida we get about 50 strikes per square mile per year, 1.5 million per year for the state. Lightning is common here during the rainy season.
Cary resident here. In NC it's pretty much guaranteed that 90% of the days between mid-May and end-July will have a 30-40% chance of thunderstorms in the late afternoon to early evening. I like it, but it can make planning outdoor activities a bit tricky.
