Looking at the metar history, the worst at de Gaulle (just behind the
cold front) was 27034G50KT (270 degs, 34 gusts 50 knots). That is
more or less straight down the runway so no serious crossswind
problems.

Before the front, 22033G47KT (220 degs, 33 gust 47 knots) so although
a crosswind, shouldn't have been a problem for modern aircraft.

It seemed to be a poor call before the event to close the airports -
it looks even less defensible with hindsight.
