Event rainfall totals varied from 2 to 4 inches in the western part of the county, to as much as 10 to 12 inches in the eastern part of the county. Numerous roads were made impassable due to standing water issues, up to 3 feet in some areas, and a few homes had minor water intrusion, particularly in the Vero Beach South area. A daily record rainfall was set at the Vero Beach Airport on Oct 9 where 7.71 inches of rain was recorded. Damage to property and county infrastructure was minimal.

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.
