We have new information in a massive red tide bloom that we have been tracking.

More testing done Tuesday shows the algae was 10 miles off Pinellas County's shore. While the red tide is patchy, it's 90 miles long, 60 miles wide and moving southeast toward us.

It has already killed thousands of fish and continues to do so. It can cause breathing problems for people if it's close to shore, but that hasn't been the case.

The red tide has been detected off the coast of Sarasota County inshore in very small concentrations. The Florida Fish and Wildlife Commission and Mote Marine Lab are both working together on this.

They tell us they're going to test the water at the Sanibel Causeway and in the Charlotte Harbor. They were supposed to test that water today, but they were dispatched to Pinellas County where there were some reports of a fish kill.

Even though it's very large, it is patchy and that's a good thing. Researchers say that means it's starting to break apart, like algae blooms eventually do.

Researchers say they still plan on testing in Lee and Charlotte counties, but they don't know when. Right now, no red tide has been detected in Southwest Florida.
