They still don't know what Isabela will do. The prediction is for it to possibly be 350 miles off of Vero by Wednesday.
Here's what is on the West Palm (Ch 5)'s website
The storm's five-day forecast placed it roughly 350 miles east of Vero Beach by early Wednesday, provided it makes a predicted turn to the northwest. Forecasters said they would know more about the potential direction of the storm late this weekend.
"The big question continues to be what will happen beyond the five-day forecast period," National Hurricane Center forecaster Richard Pasch said. "It is still impossible to state with any confidence whether a specific area along the U.S. coast will be impacted by Isabel."
