Tropical Storm Imelda caused mild to moderate beach erosion on the Treasure Coast, with officials in St. Lucie County, Martin County, and Indian River County reporting impacts to local beaches as of late September 2025. The storm’s effects on beach erosion were closely monitored by county and state agencies, as rough surf and hazardous conditions persisted along the coastline, including hazardous beach conditions reported in Martin County.
Tropical Storm Imelda Brings Beach Erosion to St. Lucie County
The main keyword, beach erosion, was a concern for St. Lucie County officials as Tropical Storm Imelda passed near the area. According to Joshua Revord, Director of Port, Inlet and Beaches for St. Lucie County, county staff surveyed the shoreline early on September 29, 2025. Revord reported “low to moderate erosion” at many county beaches.
High surf conditions are expected to continue through the week, increasing the risk of further erosion. Revord stated that ongoing rough waves could turn early signs of erosion into larger escarpments—steep slopes formed by wave action—especially at Fort Pierce Beach, which is likely to see the most severe impacts.
Safety Warnings for Beachgoers
Revord advised residents and visitors to stay clear of escarpments, warning that these features are unstable and can collapse. He also recommended staying out of the surf while storm conditions persist. According to the National Weather Service, hazardous beach conditions are expected to last through October 1, 2025.
Revord noted that some natural recovery of the beaches may occur once wind and wave activity subsides. However, he cautioned that signs of erosion, such as escarpments, may remain even after conditions return to normal. Erosion is common during the winter months on the Treasure Coast, and beach safety measures have been enhanced across all three counties to address ongoing concerns.
Martin County Beaches Hold Up Against Imelda
In Martin County, officials reported that beaches fared better than in neighboring counties. Jessica Garland, the county’s coastal program manager, said on September 28 that the beaches “have done fairly well” and “have been stable” despite high waves reaching the shoreline.
Garland explained that the dunes and beaches are protecting county infrastructure, including roads and utilities. “They’re doing their job,” she said. According to Garland, waves did not cause severe erosion, and the beaches remained intact after the initial impact of Imelda.
Continued Rough Surf and Hazards
The National Weather Service forecasted 4-8-foot waves along the Treasure Coast, peaking from late Monday through late Tuesday. Meteorologist Robert Haley advised beachgoers to avoid entering the water due to dangerous surf and rip current risks. Officials expect hazardous conditions to continue into October 1, as weather advisories remain in effect for the Treasure Coast.
Indian River County Continues Beach Assessment
In Indian River County, beach erosion from Tropical Storm Imelda is still being evaluated. James Gray, executive director of the Sebastian Inlet District, said his team is monitoring the storm’s offshore effects and will conduct before-and-after comparisons of the beaches they manage.
County spokesperson Kathy Copeland stated that a full assessment of the county’s 20 miles of beaches will not be completed until October 1. Officials are watching for lingering effects, including potential impacts to wildlife and infrastructure.
Potential Impact on Sea Turtle Nests
Officials in Indian River and Martin counties are also concerned about exposed sea turtle nests due to erosion. Garland urged the public not to disturb turtle nests or eggs, which are protected by state and federal law. According to Florida Atlantic University, only 4% of the season’s 11,000 nests remain, with most hatchlings having already reached the ocean.
Ongoing Monitoring and Official Sources
All information regarding beach erosion and storm impacts is based on statements from local officials, the National Weather Service, and county agencies. According to a preliminary report from the National Hurricane Center, Imelda’s center was about 216 miles southeast of Cape Canaveral at 2 p.m. on September 29 and was expected to continue moving parallel to the Florida coast before turning east-northeast.
Officials emphasize that details may be updated as assessments continue and as the storm’s effects are fully evaluated. For the latest information, residents are encouraged to consult official county and weather agency updates.
