The worst storm of the season so far was on track to hit Hong Kong as Typhoon Nida barreled Monday toward south China. The Hong Kong Observatory, a government weather agency, issued a No. 8 storm signal late Monday as schools suspended classes and airports canceled more than 120 flights. No. 8 signals indicate that gales or storm-force winds are expected with sustained speeds up to 72 mph and gusts up to 112 mph.
