Japan Tsunami Debris Reaching West Coast Already?

This video shows what appears to be debris from the Japan Tsunami reaching the shores of Vancouver yesterday. But could it have really made it that far, that fast? NOAA's initial simulation didn't have it reaching the western North American shores until March 2013:

I was a little disappointed that the Associated Press didn't find out whether the languages printed on the objects were "Japanese or Chinese," as that would make a difference. Of course, as the interviewee points out, plenty of junk washes up on shore on the west coast, and some of it may be from boats dumping trash.

I believe further investigation is warranted, but the Daily Mail does not, quoting a local oceanographer from Seattle, where more debris was found. Although the NOAA map shows most of the debris missing the coast, the oceanographer quoted said that 100 million tons will arrive. That's a pretty big disagreement but I'm more likely to believe NOAA, who has an entire Marine Debris department.
