It appears that a noxious red tide algal bloom has reached one of Florida’s main metropolitan areas.

The Tampa Bay Times reported Sunday that hundreds of thousands of dead fish have been found on and near roughly 20 miles of beaches located in Pinellas County on the Gulf Coast.

County and city crews cleaned up fish that washed up on the shore. A Pinellas County environmental official told the newspaper that she expects the clean-up to run through this week.
