I was a bit west of the plant last week when the Coast Guard came to check a boat that was inside where the bouy line would be. The bouys were not out but he would definitely have been within them. I was about 1/4 mile away. After a long time with him, they came and did a safety checkhart on me. All was OK and they were completely professional.
With such a large rise in temp, you may have been too close.
