The Florida Department of Health Palm Beach County has posted health advisories for two local beaches.
Water samples off the Dubois Park Lagoon in Jupiter and Kruesler Park in Lake Worth Beach tested in the poor range, with high levels of dangerous bacteria.
Causes are unknown but generally associated with runoff following heavy rains.
More samples will be taken and more tests will be conducted to determine whether to lift the no-swim advisories.
