BEIJING, Feb. 28 (Xinhua) -- China's national observatory issued a yellow alert for snowstorm for Wednesday and Thursday as heavy snow continued to hit northeastern China.

The National Meteorological Center said snowstorms would hit parts of Heilongjiang, Jilin and Liaoning provinces, dropping 5 to 15 centimeters of new snow. Some areas are expected to see blizzards.

The center advised residents to stay indoors and asked local authorities to take precautions on roads, railways, electricity and telecommunications.

A cold front will hit parts of North China and bring temperature drops of up to 10 degrees Celsius, according to the center.

In the country's four-tier weather warning system, red is most severe, followed by orange, yellow and blue.
