| China was hit by snowstorms and a significant cold wave over the weekend, and the extreme conditions are expected to persist as the country approaches the new year on Wednesday. | China was hit by snowstorms and a significant cold wave over the weekend, and the extreme conditions are expected to persist as the country approaches the new year on Wednesday. |
| Temperatures are forecast to drop to more than 10C (50F) below the seasonal average in some areas, with northern regions experiencing the most severe weather. Maximum temperatures in Shenyang are expected to plummet by more than 13C, while Yinchuan could tumble to -8C. | |
| Snowstorms have been affecting north-western China, with accumulation reaching 8cm in some areas. Additional snowfall is expected later this week, potentially disrupting travel during the festive period. | Snowstorms have been affecting north-western China, with accumulation reaching 8cm in some areas.

| The cold wave is caused primarily by a weakening of the polar vortex, allowing cold air from the north to push farther south. This is exacerbated by a high-pressure system known as the Siberian high, which is funnelling cold and dry air from Siberia southwards, trapping it over the region and intensifying the drop in temperatures. | |
| The high pressure and associated cold air over China has extended south into Thailand, triggering a notable fall in temperatures and strong winds in the country. Northern, central and eastern Thailand – including the capital, Bangkok – have experienced temperature drops of 2-4C, with 3-5C in the north-east. | The high pressure and associated cold air over China has extended south into Thailand, triggering a notable fall in temperatures and strong winds in the country.

| According to the national meteorological department, the La Niña phenomenon is likely to bring strong south-easterly winds in the coming months. This will cause increased humidity, a higher frequency of thunderstorms and cooler-than-average temperatures. | According to the national meteorological department, the La Niña phenomenon is likely to bring strong south-easterly winds in the coming months.

| Meanwhile, Alaska was hit by extreme stormy conditions over the weekend, including heavy rain, strong winds and snow, prompting blizzard warnings. Gusts of 70mph (116km/h) lashed southern regions and heavy rainfall caused significant flooding in low-lying areas across southern and central Alaska. | Meanwhile, Alaska was hit by extreme stormy conditions over the weekend, including heavy rain, strong winds and snow, prompting blizzard warnings.

| Avalanche warnings have been issued for several areas including Turnagain Pass, Summit Lake and Chugach state park. The combination of intense winds, heavy rain and snowfall has created unstable snow conditions, increasing the risk of avalanches. The temperature is expected to plunge by the end of the week as cold polar air returns, potentially the coldest the season. | Avalanche warnings have been issued for several areas including Turnagain Pass, Summit Lake and Chugach state park.
