Event narrative

Seminole County Emergency Management reported significant urban, street, and low-lying flooding as a result of 4 to 8 inches (southeast) 8 to 12 inches (northwest) of rain in association with Hurricane Milton. A period of very heavy rainfall rates associated with the core of the storm led to flash flooding during the overnight period (Oct 9 - 10).

The heavy rain that fell as a result of the storm also led to a long-term river flood event along the St. Johns with the river near Geneva entering major flood on Oct 14, peaking at 10.15 feet on Oct 15. At Deland, the river rapidly rose to major flood stage on Oct 11, peaking at 5.49 ft on Oct. 14.

Wider weather episode

Hurricane Milton moved ashore the west-central Florida coast as a category 3 hurricane on Oct 9 around 1930EST. The system continued slowly in an east-northeast trajectory across central Florida, becoming a category 1 hurricane before emerging into the Atlantic Ocean near Cape Canaveral. The outer rainbands of Milton overspread the Florida peninsula earlier in the day, leading to a prolific tornado outbreak across Okeechobee, Martin, St. Lucie, Indian River, Osceola and Brevard counties with over 19 confirmed tornadoes within a 4-hour period. Milton's slow forward motion produced very heavy rainfall, with significant urban and street flooding particularly near and north of the center's track, as well as a significant river flood event along the St. Johns. Considerable tree damage and some structural damage occurred due to the system's tropical storm force winds, and hurricane force wind gusts, particularly near and north of the track of the center.
