Much of the official english-language resources (e.g. summary bulletins) are available at this page: http://www.bangkokgis.com/flood/index.php. However, a picture is worth a thousand words and the people at our hotel in Bangkok were mostly glued to Thaiflood, refreshing a couple times an hour:
The Flood Monitoring System is a clearing house for satellite data, the office of which is shown below (and there's a gallery of photos of the office in action)
|The GIS "War Room"|
|Longdo also has overlays of flood direction|
This United Nations sponsored webpage UNITAR-UNOSAT also allows people to upload Geotagged digital photos and combines it with various layers of information, such as flood extent:
Again, all this is just flood monitoring, but for maps of forecasts, the Bangkok Post recently posted an image from the Disaster Warning Centre, describing a "Worst-case scenario". This somewhat resembles Bangkok's land elevation map, the medium blue areas in the south center area being the lower elevations (and hence some of the deeper flooding).

A phrase like the "worst case scenario" is a double-edged sword. This is the kind of information that decision-makers crave and request from forecasters. But what is the chance of this worst case scenario happening? 1 in 3? 1 in 10? 1 in 100? History is filled with examples of where the actual outcome was above the worst case scenario and decisionmakers ended being very resentful of this. Of course, forecasters could instead conjure up a wildly high scenario (e.g. take the above map and multiply it by 3), but this leads to wasteful overplanning and its own form of resentment.
