BEIJING, Oct. 6 (Xinhua) -- A cold front will chill most parts of north China on Saturday, the country's national observatory said Saturday.

Most parts of Inner Mongolia, northeast and northwest China will see strong winds and temperatures 4 to 8 degrees Celsius lower than Friday, the National Meteorological Center (NMC) said.

Temperatures in some parts of Inner Mongolia and northeast China will decrease by up to 10 degrees Celsius, the NMC forecast.

The northeastern part of Inner Mongolia and northwest Heilongjiang will be hit by light to moderate snow or sleet, said the NMC.

The observatory also renewed a blue alert for Typhoon Kong-rey, this year's 25th typhoon, on Saturday morning.

The eye of Kong-rey, which was located over the ocean in the Korea Strait as of 5 a.m., is expected to unleash gales in northeast China.
