Th e Florida Department of Health in Collier County is advising the public not to enter Gulf waters due to increased risk of water-borne illness due to Hurricane Helene .
Swimming is not recommended because bacteria from street flooding and storm surge can be carried back into the Gulf after flooding recedes.
The health department conducts water quality testing on a regular basis and testing at specific beaches for bacteria levels should resume in the days after Hurricane Helene has passed.
Coastal areas in Marco Island, Goodland, Everglades City, East Naples and Naples experienced storm surge flooding Thursday morning before Helene passed and authorities advise that more flooding is possible.
