FORT MYERS, Fla. -  A WINK News viewer provided reporter Kyle Jordan with suspected tar balls, found on Fort Myers Beach this morning. The possible tar balls were found  just outside the Lani Kai; they've also been reported in the area of Diamondhead.

The Coast Guard tells WINK News that right now, it is not concerned about the black tar-like balls. 

The Fort Myers Beach Chamber of Commerce will hold a public meeting tonight about the spill's potential impact.  It begins at 5:00 p.m. at the Pink Shell Beach Resort.

The Coast Guard has confirmed that 20 were found on Monday in Key West; they have been sent off to a lab for analysis. Park rangers at the Fort Zachary Taylor State Park were finding the clumps at a rate of three an hour Monday.

Notably, tar balls can occur naturally or they can originate from other sources, like ships.

University of South Florida researchers are forecasting that oil from the spill off Louisiana could reach Florida's Key West by Sunday, March 23.

The southern arm of the massive oil spill has entered or is near the Gulf of Mexico loop current, which circulates water from the Gulf to the Florida Keys and toward the Gulf Stream.

Experts believe that the Gulf Stream may eventually take the oil slick up Florida's Atlantic coast. USF scientists use currents, wind forecasts and other elements to make their predictions.
