Episode notes
Understanding 100-Year Floods
- A 100-year flood means a flood has a 1% chance of occurring in any given year at a location.
- Increasing extreme rainfall makes these odds likely underestimated now, possibly twice as high in many areas.
Check Local Floodplain Maps
- Texans should check their local floodplain maps on FEMA's website to understand flood risks.
- Know safe evacuation routes that avoid floodplains to prepare for flooding emergencies.
Climate Change Enhances Flooding
- Climate change is not the sole cause of catastrophic Texas flooding but acts as an enhancement factor.
- It intensifies rainfall by about 10-15%, combined with factors like tropical storm remnants and hurricanes.
