I am seeing plenty of signs from the SEO community, the tracking tools and so on that there was and is a Google algorithm update going on right now. It started on March 12th, yesterday and is continuing on today. It is early on, this is not confirmed by Google, but I am seeing plenty of chatter and signals of an update.
Update: This is now confirmed by Google:
This week, we released a broad core algorithm update, as we do several times per year. Our guidance about such updates remains as we’ve covered before. Please see these tweets for more about that:https://t.co/uPlEdSLHoXhttps://t.co/tmfQkhdjPL

The last update we reported on was also unconfirmed and was on March 1st, before that February 27th and February 22nd.
The ongoing WebmasterWorld forums have these comments from SEOs:
I mean today. The last 5 hours. I think google made huge adjustments in the medicine sector.
People are seeing changes?
Yes, big flux going on here in USA. Should be interesting to see what Google does for ecommerce. The last update was horrible. Google can’t take away anymore converting traffic because it’s all gone. Google is dead….
yes, I can see also a improvment arround 10-20% and we made NO changes.
For example we have lost our (non commercial) main keyword on EAT in august. Drop from position 1 to 8. This keyword and a few more are now back to position 2.
Now for the tracking tools that track fluctuations in the Google search results.
Mozcast (Ill update it later today):
Have you noticed changes in the past 24 hours or so? Please let us know.
