Red Tide Confirmed Along Local Beaches.
PANAMA CITY BEACH, Fl., Oct. 14 - If you have been to the beach in the last day or two you no doubt have noticed the irritation to your throat and eyes.
The problems are the beginning stages of Red Tide. The west end of Panama City Beach is already having a problem with dead fish washing up on shore. Red Tide is an algae bloom which depletes oxygen from the water causing the fish to suffocate.
It also creates irritants, which are generally not harmful to humans, although those with breathing problems may experience some more difficulties than normal.
Many people are already reporting raspy throats, coughing, inflamed sinus and red-watery eyes.
Earlier tests for Red Tide in local waters came back negative. But, new tests done on Monday show what some residents feared. What we are seeing now is the beginning of the Red Tide. The test results were confirmed late Monday by state biologists.
