PROJECT ALERT NOTICE (FL) Flood measurements

Date: Fri, 30 Sep 2022 09:38:18 EDT

Summary: Rainfall from Hurricane Ian caused widespread flooding in Florida

This project alert covers the central Florida area north to the Florida border. Hurricane Ian made landfall on Wednesday, Sept. 28 as a Category 4 storm and dropped record rainfall across southwest and central Florida. The hurricane weakened as it moved onshore, and some areas received an estimated 20+ inches of rainfall in less than 24 hours. Tropical storm force winds continued into the day on Thursday making immediate event response impossible.
Significant property damage and flooding occurred, and the National Guard and local first responders performed emergency evacuations yesterday in the St. Johns and Kissimmee River basins. Approximately 20 streamgages experienced peaks of record, and this number may increase in the next week as streamgages are repaired and as the runoff reaches the receiving rivers. 17 streamgages were damaged.

A total of 11 field personnel from the Orlando, Florida office responded Friday morning, Sept. 30, to repair streamgages and measure streamflow. They plan to measure 12 and repair 3 streamgages, if possible.
