The Australian Transportation Safety Bureau's (ATSB) website
now has an extensive section devoted to the MH370 search: Australian Transportation Safety Bureau - MH370 - The Search for MH370 Continues
Of particular interest is the ATSB's Progress Report
section, which has a map posted on it. The map has 'Priority Search', 'Medium Search' and 'Wide Search' areas labeled on it. On the bottom right corner of the map are "Day of Release" and "Map Number" labels, so I presume this map will be regularly updated.
The website also includes MH370 external links, Frequently Asked Questions (FAQs), an explanation of the 7th Arc, Definition of Underwater Search Areas, Three-dimensional models of the seafloor terrain and Bathymetry Survey Data.
I also assume that this ATSB website was the source for the BBC News article above.
