this is a hugely threatening storm, but it's also very ominous because it's so unpredictable and slow. >> that's the main thing. it's so slow. this is incredibly powerful. this is not just barely a category 5. this tops the category 5 threshold by leaps and bounds. this is the strongest storm to ever hit the bahamas. it has made that first land hall, the an co-islands that's part of the bahamas. it's moving at a snail's pace. you can pretty much walk fast or jog faster than this storm is going. and it's go ing to sit over the bahamas for a good 36 hours at least before making that northward turn. and so when you think about that, 185-mile-per-hour winds, gusts higher than 200 for a 36-hour duration, that is unprecedent. so this is moving at seven miles per hour right now. it's going to slow even more before this takes a turn to the north. and how soon that turn happens
