I’m sure you’ve seen the videos of hurricane Fiona in Puerto Rico… here’s some of the rain & flow data to better visualize the impacts of this storm. 

Flow – river increased from 150 cfs to 83,000 cfs in half a day. Watershed is only 120 sq miles. Gage sits 13’ above sea level.

2017 Hurricane Maria had more rain to produce a peak flow of 68,300 cfs, 3rd highest peak in 49 years of data.

Highest peak flow recorded was 128,000 cfs, September 16, 1975 from Hurricane Eloise in a 120 square mile watershed ! Wow!
