An extreme precipitation event in 2008 cost one Upper Midwest town more than a million dollars in infrastructure repairs. Now, other municipalities can simulate how a similar event might affect them.

Flash floods scoured Phoenix and surrounding areas on September 8, 2014. How did the rainfall totals compare to normal September precipitation?

On August 25, 2011, Dr. Elwynn Taylor, Iowa State University’s Extension Climatologist, tweeted to Iowa corn farmers: “Weather based statistics indicate a US corn yield of 149BPA, the prime factor this year is the Aridity Index.” Taylor uses NOAA climate information and seasonal outlooks to help thousands of the region’s farmers manage risk. Nearly 5,000 followers look to his Twitter feed for guidance.
