....... be replaced. I was surprised the flooring is not tongue-and-groove; it's just flat nailed. I don't suppose that helped, but I believe the main problem is just residual moisture that came in through the open door and worked it's way in over time. The rest of the floor is fine, and it doesn't appear the sub-floor or sleepers below the afflicted area have buckled, although need to investigate that more to verify we don't have a more extensive problem.
Anyway, we've been thinking about what to do to fix the problem and prevent a re-occurrence. Have considered cutting out the flooring and installing tile in front of the entire door area, (something like a fireplace hearth), and maybe running a dehumidifier during rainy times.
Some of the material suggestions in this thread are interesting - we'll have to look into them as well.
When I put flooring down I sealed the wood as to minimize or slow down the absorption and expelling of moisture, especially near doors. Tile of course would fix this and given the boards are not tongue and grove will allow for moisture to leach in.

agree on the WaterHog rugs. Have a couple and with rubber bottoms, should be waterproof while offering cushion. I'm sure there are others out there making similar. Just ask a manager at a business or two should you see something, too hit the custodial service businesses.
If you can't find the cushion needed, or pricing of thick stuff is prohibitive, then you could opt for cork underlayment between a waterproof rug. Cork is sold in various thicknesses and typically in rolls but one outfit sells it in sheets to eliminate warping. Typically in 3, 6, etc mm thicknesses. It can be pricey too. then one can consider other underlayments such as rubber (farm stores usually have it by the foot) and even thick felt at carpet stores.
of course that beckons the obvious, hitting an established carpet/flooring store. Most have commercial product that would/could save a lot of expense of replacing damaged floors.
then too, if waterproof you will want to move it every so often as to ensure you haven't trapped moisture under it only to find it 4 months later in a black slick mildewed state ...
