We have quite a deep low pressure system just off the New Jersey coast tonight. A weather station I set up along the Jersey Shore with a fairly accurate barometer recorded a pressure of 967.7mb I believe that is the lowest pressure that particular station has ever recorded in its two years or so at the location.
In addition to having a central pressure lower than 968mb (some hurricanes don't ever get that low) the storm may still be intensifying. Heavy waves of precipitation are still pushing northward into Cape Cod which probably is an indicator of continued deepening, and the pressure at the New Jersey shore continues to drop despite veering(clockwise turning) winds which would normally indicate the center of the storm passing a location and better weather on the way.
I'll leave you with some real time images to track the storm with
