Dozens of flights, trains and ferries scheduled for Monday and Tuesday were canceled on Monday as China issued its highest alert for Typhoon Nida, which was heading toward Guangdong province and neighboring southern areas.

Nida, the fourth typhoon to hit China this year, was moving northwest toward southern and southeastern China. It was forecast to make landfall in the central coastal part of Guangdong on Tuesday morning, said DongLin, an expert in typhoon forecasting at the National Meteorological Center.

The center issued a red alert, the highest emergency response among the four-tier national system, on Monday afternoon, warning of squalls, heavy rain and rough seas.
