The chatter and discussions around a Google search algorithm update is pretty strong this morning in the ongoing WebmasterWorld forums. It is very early on the chatter side, as it seems the ranking fluctuations have just started early this morning or late last night. I suspect we will see even more chatter over the weekend.
It may have been from the tremor we saw earlier this week or not. I will reach out to Google to see if something is up with this one, but I doubt they will reply with anything more than their normal statement about always making updates…
Here are some comments from webmasters and SEOs:

But today, my “human” traffic is up by a solid 30% from North America and Europe.

I’m seeing an improvement today as well. Unfortunately, traffic is still down 20-25% from what it was before the big Google update in May, but it’s at least better than it was all summer, and it’s been slowing improving all week.

Further losses in traffic yesterday, now about -75%, and this morning is looking even worse, however I can’t see why!

Please do check your traffic, rankings and analytics to see if you saw any impact as of this morning or not.
The automated tracking tools are showing signs as well, at least the ones that seem to have been updated with today’s data thus far. Here are some of those tools showing weather turbulence with Google today.
