Normally not that many (likely somewhere between 2000-5000, but almost certainly <10k; depends on time day, etc.) although the visitors may well be bunched up around the time the article comes out.

What can make traffic explode is if other news sites pick up on the article to do their own or if it triggers a viral response on twitter. But if you keep an eye on things you should have enough advance warning if that happens.

I'd make sure you have a good "about" page, the value of a techcrunch article isn't the amount of visitors but rather the fact that the visitors are often high-value (journalists, investors, M&A people, job seekers, etc.) so at the very least have an about page with mini-bios of the team, location and contact information.
