This intense cyclone that made landfall on the east coast of #France is one of the more extreme cases of explosive cyclogenesis I can recall.

Just 24h ago there was not even a closed low. Now, a rapidly intensifying sub 970-hPa cyclone with wind gusts nearing 100mph! https://t.co/zQv0Sq4O9K pic.twitter.com/djEQbW1Wns
