Updated models reveal serious shortcomings in infrastructure readiness

The federal government's estimates of flood risk are outdated and do not account for the effects of climate change.
New analysis found that over 100 million Americans live in areas with a much higher risk of extreme rainfall than government models predict.
Billions of dollars in infrastructure funding could be misdirected due to the government's outdated rainfall models.
The atmosphere is changing in many places, bringing more frequent and intense periods of extreme rain, yet infrastructure projects rely on models that do not reflect this.
NOAA's updated model will not be ready for several years, leaving many projects without the needed information to ensure they can withstand future conditions.
