This is a 'superstorm' period in English & US usage of the word meaning it
is likley to include in the most exposed parts of main storm tracks winds
gusting to over 160kph (100mph) - i.e. resulting from hurricane force winds
of Beaufort force 12 average wind speed.


But "superstorm" is not in current English and US usage, nor has it
ever been. It has no formal definition, except that supplied by
Weather Action themselves.

I've seen a later proclamation talking of "hurricane force
gusts" (sic), not mean wind speeds.
