Narrative:

Departed teb on ruudy two SID. As this was the first time for me; I studied it before departure. I wasn't exactly sure if the FMS would head 240 degrees to intercept 260 degree track to ruudy or not or if I had to do any action. Please understand the weather was truly terrible. Thunderstorm had joined with a fairly strong fall cold front bringing rain and wind to new york area. We took off with 25 KTS gusting to 37 KTS. As this was a strong crosswind; the heading track to ruudy was strange to say the least. Well; at ruudy the FMS CDI swung around to a 160 degree turn; i.e.; I almost made a u-turn. I knew this couldn't be right so I just selected the dto function to brezy; the next fix. I turned to brezy and was stabilized on course for 2 minutes or so when approach told me I should have been heading 280 degrees from ruudy not brezy. I missed that on the chart. He was right. In writing this; it sounds like I'm an idiot; but in this weather and in this crowded; difficult airspace (that I am not all familiar with); I wonder if any one else could have done better. Lesson learned: I should have used the autopilot earlier in the flight.

Title: A high performance corporate jet Captain departed on the TEB RUUDY TWO departure and because of a high cross wind track deviation lost situational awareness and then the FMS apparently did not track accurately. The reporter pickup an inaccurate heading and had to be corrected by ATC.
