unfortunatly they still don't see a problem. Hydro Quebec is still going by NOAA's K index, this is a index that measures the change in magnetic activity over the course of 3 hours and magnetic storms can change very rapidly so when NOAA issues a K-index observation you have no idea if the change they are showing occured in a minute or gradually over 3 hours. keep in mind that it is the rate of change that will induce currents in the transmission system.
unfortunatly power companies in the states have little (if any warning). NOAA often posts a warning and the observed information in the same minute. the only system in the world that currently has any real advanced warning system is the power grid in England and Wales. they have about a 45 minute advanced warning of geomagnetic activity and how it will effect the power grid.

CME generally take 2 to 3 days to reach us, so tuesdays story is still of concern.
