These stores currently have positions listed at jobs.sears.com that explicitly mention "Store Closing" in their descriptions. In reverse chronological order:
Las Vegas NV - Kmart - 2/4
Hemet CA - Sears - 2/4
Humble TX - Sears - 2/4
Hookset NH - Kmart - 1/18
Richmond CA - Sears - 1/7
Hookset was part of a previously announced round of closings, but I don't think the other four were.
