Typhoon Rammasun (the strongest storm to hit southern China in 40 years) arrived at the southern Chinese island province of Hainan on Friday, then moved on to strike parts of the mainland later on Friday and early on Saturday. Clocking sustained winds of 155 mph and gusts up to 175 mph, Rammasun is now one of the strongest typhoons to make landfall in mainland southern China on record. It is not over… What next?
