Episode notes
Flash Flood Dynamics
- Flash floods occur rapidly with intense rainfall over small areas, often surprising people.
- Urban pavement and steep topography worsen flooding by funneling water quickly into rivers.
Understanding "Corn Sweat" Effect
- Corn crops in the Midwest transpire water vapor, increasing humidity during heat waves.
- This "corn sweat" intensifies heat waves by raising moisture levels in the air.
Tips for Staying Cool Safely
- Avoid outdoor exertion during peak heat and stay hydrated with loose, light clothing.
- Use air conditioning, fans, blackout blinds, and seal windows to keep indoor spaces cool.
