Mike, 'frizzle top' is caused by a nutrient deficiency, I thought it was magnesium, but Erik says manganese.
It looks like the very top fronds have been fried with a blowtorch, or permed (like to curl yer hair, y'know?)
In any case, a sprinkle of a slow-release complete fertilizer specifically formulated for palms will prevent it. Here in FL we have a company called Lesco that makes a good one. Don't know if it's available nation wide.
