This is not good. I've been following her blog daily, and the picture is one of a person with progressive fatigue, who is sometimes making poor decisions. For example, a day or two ago, she went to bed with the wind rising, without reefing her sails, a standard precaution. This happened apparently, because she hoped it would settle down. It didn't. She did this in the most problematic area on her trip. Bad decisions in this environment tend to "stack", creating much more dire situations. I'm not quite sure what would have made her trip her manual EPIRB, but not trigger her automatic. The problem is that all the electronics that were enlisted to compensate for her inexperience and lack of strength, are failing.
Let's hope she is ok, but time is critical, and a lot seems to have passed.
