Well, Danielle didn't make it north of 38 North as a hurricane, but Earl might set a record for the first known Cat 4in the high latitudes on Friday. When we say "high" latitudes we're talking unusually far north, say the latitude of Syracuse, New York. Normally, hurricanes don't give birth at such latitudes, let alone get to Cat 3 or 4 status. A Cat 4 would certainly be unprecedented that far north.
