Series W of the MUTCD is for warning signs.
Temporary warning signs
This series includes warning signs for temporary traffic control zones, i.e., construction zones, as well as for incident management areas. Whereas a regulatory sign appears the same inside and outside a construction zone, a temporary warning sign has an orange background instead of the usual yellow, and an incident management warning sign has a fluorescent pink background. California and Texas place construction warning signs in separate series C and CW, respectively. Incident management area signs are not to be confused with the emergency management signs of Series EM.

Incident management area
In general, OpenStreetMap only maps long-term closures and construction sites. For routing purposes, short-term construction is more reliably and efficiently tracked in incident management systems along with real-time traffic congestion data. However, if a temporary warning sign happens to be posted on a long-term basis for some reason, you can map it as you would map a permanent warning sign. If you map the temporary traffic sign as a node, use a W code but add colour=orange or pink to the node.
