Episode notes
Hurricane Categories Misleading
- Hurricane categories only reflect wind speed, not size or rainfall.
- A large Category 4 hurricane can be more destructive than a small Category 5.
Warmer Oceans, Wetter Storms
- Warmer oceans lead to increased water vapor, fueling stronger hurricanes and heavier rainfall.
- This compounding effect results in disproportionately more rain than just from increased atmospheric moisture.
Harvey vs. Helene
- Hurricane Harvey stalled over Houston, drawing moisture from the Gulf and causing massive flooding.
- Helene, while fast-moving, still caused inland flooding due to high moisture content.
