A low pressure system that could impact South Florida is poorly defined, but the National Hurricane Center is still calling for a 70 percent chance of tropical cyclone development.

Local 10 News hurricane specialist Max Mayfield, who served as director of the NHC from 2000-07, said the computer trajectory models vary. He said one brings the system on a path to South Florida, another takes it about 500 miles east of Florida and yet another has it headed closer to Bermuda.

Conditions remain conducive for development as a tropical depression or tropical storm. The mountainous terrain of Hispaniola could limit development during the first part of the weekend, but conditions are expected to become more conducive for development by Sunday when the system is forecast to move near or over the Bahamas.

"It's still something we have to watch, but nothing we can really grab hold of just yet," Mayfield said.

The next named storm would be Cristobal.
