The Vero Beach High School Main Campus, Freshman Learning Center, and Rosewood Magnet will be open Thursday, the district announced.
Weather-related problems forced their cancelation Wednesday.
There are contingency plans for students whose classrooms may need to be moved at Vero High’s main campus.
Some areas might also be off limits.
The district says staff members “are taking the necessary precautions to ensure students return to a safe learning environment.”
