When the local FSS were closed NavCan recognized that the briefers in the
centers may lack the local knowledge that the local FSS had provided. A
project to gather this local knowledge for briefer training lead to the
production of weather manuals for each of the weather regions. These
manuals are available on their website. The general weather chapter seems
to be common to each manual.
