The answer to the short notice is due in at least part to administrative procedures. Emergency regulations are limited to just 120 days. In that at least part of the season just modified go through May they can offically be enacted until early February. Any news release put out well advance of that time would have to be so full of "maybe"s and "likely" that it may be more confusing then what we currently have.
