Storms
After enduring a freezing cold with temperatures in mountainous areas dropping to minus four degrees Celsius, northern Vietnam is to undergo another fresh cold snap starting Saturday.
Deputy Director of the National Hydro-meteorological Forecast Center Le Thanh Hai said the new cold bout will drive down temperatures in mountainous provinces to under 10 degrees Celsius and even lower in higher mountainous areas.
Temperature in delta region provinces will dip to 11-12 degrees Celcius.
The Center also predicts an even stronger cold front on January 21 lasting until January 25.
More than 350 people have been killed after floods and landslides devastated towns and villages in a mountainous area near Rio de Janeiro.
Rescue workers were digging desperately on Thursday in an attempt to reach people buried after the equivalent of a month's rain fell on the Serrana region in less 24 hours, toppling houses and buckling roads.
"It's like an earthquake struck some areas," Jorge Mario, the mayor of Teresopolis, where at least 168 people were reported to have died, said.
"There are three or four neighbourhoods that were totally destroyed in rural areas. There are hardly any houses standing there and all the roads and bridges are destroyed."
Television images showed emergency workers going through the ruins of collapsed homes in a search for survivors, but often finding only bodies.
The heavy downpour continues in Rakiraki, Tavua, Ba, Lautoka, Korovou and Naqali.
The Department of National Roads said people are still stranded on the main highway to Rakiraki town near Vaileka as the highway is still flooded and closed to traffic.
The FSC road and crossing, the Waimari and Korotale roads are also flooded.
On the East Nusa Tenggara island of Flores on Wednesday, high waves that reached as far as 100 meters inland swept away at least 18 houses in Sikka district's Nangahale village, said Fransiska Palan Bolen, secretary of the province's Natural Disaster Management Agency (BNPD).
No injuries were reported in the incident.
Fransiska said the affected villagers had been evacuated to emergency camps and that her office had sent personnel, supplies and food to help the victims.

Roy Williams of Westfield, Massachusetts, shovels snow from in front of his car on a ramp to Interstate 91 south during a winter storm in Windsor, Connecticut, on Wednesday.
Hundreds of schools remained closed in Massachusetts as crews continued to clear snow and to salt icy roadways, according to state Emergency Management spokesman Peter Judge.
The state's 250 National Guardsmen -- who were mobilized as a precautionary measure on Wednesday -- were relieved from duty by Thursday morning, Judge said.
Delta Air Lines canceled more than 200 Delta and Delta Connection flights in an effort to minimize delays, the airline said. It had canceled 1,300 flights Wednesday because of the storm.
Amtrak, which had suspended rail service between New York City and points north, resumed full service by Thursday morning, according to Amtrak spokesman Cliff Cole.

A partially submerged vehicle is seen after a landslide in Teresopolis, Jan 13, 2011.
Torrents of mud and water set off by heavy rains left a trail of destruction through the mountainous Serrana region near the city of Rio de Janeiro, toppling houses, buckling roads and burying entire families as they slept.
"It's like an earthquake struck some areas," said Jorge Mario, the mayor of Teresopolis, where 185 people were killed and scores more were feared dead.
"The death toll is going to climb a lot. There are a lot of people buried who can't get help because rescue teams can't get there," Mario said, adding that three of the town's neighborhoods were destroyed by the flooding.
The mudslides swept away the homes of rich and poor alike in and around Teresopolis and other towns, likely causing billions of dollars in damage. But the brunt of the disaster was borne by poorer rural residents in houses built in risky areas without formal planning permission.
The floods have not affected Brazil's main export crops -- soy, sugar cane, oranges and coffee -- although they could push up local food prices further as the small Serrana region is an important producer of fruit and vegetables for the Rio metropolitan area.
Television images showed rescuers trying to haul residents from raging floodwaters, and going through the ruins of homes in search of survivors, often finding only corpses. One success came when a 6-month-old baby was rescued alive from the rubble of a house, drawing thunderous cheers from residents.
The red alert, which is a maximum level on a scale of three (yellow, orange, red) was due to come into force at 3 pm local time (GMT+11), the French High Commission in Nouméa said in a release.
The red alert effectively means that people should stay indoors until further notice and continue to monitor cyclone-related advice on local media.
A previous orange alert had been imposed on the Loyalty Islands, on Wednesday, prompting the population to store goods and essential items such as batteries, water and food.

Cars sit in debris in a flooded street in Teresopolis, Rio de Janeiro state, Brazil, Wednesday Jan. 12, 2011. Torrential summer rains tore through Rio de Janeiro state's mountains, killing at least 140 people in 24 hours, Brazilian officials said Wednesday.
Rescuers used heavy machinery, shovels and bare hands to dig through debris in a search for survivors Wednesday. It was not immediately clear how many people were rescued. At least 50 remained missing, and officials feared that figure would rise.
In Teresopolis, a town 65 kilometres north of Rio, the rain overflowed creeks and flash floods swept over already water-logged mountainsides. Brick and wooden shacks built on hillsides stripped of trees were washed away in surging earth and water, leaving behind only a long trail of rusty red mud.
Heavy rains and mudslides kill hundreds of people across Brazil each year. Especially punished are the poor, whose rickety homes are often built on steep inclines with little in the way of foundations.
At least 114 people died in Teresopolis, the local Civil Defence agency said. The mountains saw 26 centimetres of rain fall in less than 24 hours.
Southerners seemed resigned to waiting out winter headaches such as slick roads and paralyzed airports. But people from Ohio to New York, who face up to a foot of snow in their third blast of winter in as many weeks, were already putting pressure on state and local governments to spare them from travel tangles and snow-choked roads.
Across the South, communities remained encrusted in ice and snow for a second straight day. Road crews fared little better than in the storm's opening hours, owing mostly to their lack of winter equipment. Frustrated motorists sat idle on slippery pavement or moved at a creep. Millions of people just stayed home.
In Atlanta, which had only 10 pieces of snow equipment when the storm hit, officials planned to bring in nearly 50 more pieces - the most resources marshaled for a storm in a decade. Mayor Kasim Reed said backup supplies of salt and sand were on the way, too.
Mail delivery was restricted to just a few places because postal employees could not get to work. Many schools and other institutions planned to stay closed Wednesday out of caution. The storm has been blamed for 11 deaths and many more injuries.
Despite the inconvenience, Southerners confronted the aftermath with patience - and a certain amount of wonder.
Heavy, wet, pasty snow poured over eastern Massachusetts, stuck to everything and caused thousands of power outages.
Several reports of thunder and lightning came into the weather office before sunrise, as intense bands of snowfall rotated onshore.
The snow was a bit lighter and fluffier well inland, so it was a bit easier to move and shovel out in Worcester County.
Across the extreme South Shore and Cape and Islands, the snow is mixing with sleet and rain at times making for a big mess.
Time Frame
The heaviest snow, 1-to-3 inches per hour, continued through midday.
Steady moderate snow will fall for most of this afternoon and then becoming lighter by this evening.
