Night clouds can be seen in about an hour after sunset, said the head of the Hydrometeorological Center of Russia

Unusual noctilucent clouds can be seen in the night sky over Moscow. This was announced on Wednesday TASS director of the Hydrometeorological Center of Russia Roman Vilfand.

He noted that this phenomenon is a beautiful decoration in Summer sky. Such clouds can be observed on 4 and 5 July in the clear sky at night.

"These clouds are visible at night, they are often also called nocturnal clouds They are silvery and beautifully lit at night. When the sun sets, its rays penetrate deep into the atmosphere, penetrating it with light." - Vilfand said.

According to him, the noctilucent clouds are a cluster of molecules of water vapor. "These clouds are very high, at a distance of about 100 km from the surface of the Earth. To predict their occurrence can not be because we do not understand their nature. They appear in the summer, and the nature of these clouds is not fully known..." said Vilfand.

Circumhorizontal arc creates brilliant display in clouds over Nanaimo, BC

The colours in the sky never cease to amaze me; from cool sunrises to brilliant sunsets, to rainbows and halos around the sun.

Karen Butler of Nanaimo snapped a few pictures of bright colours dancing across the clouds a few days ago, the result of a circumhorizon arc.

A circumhorizon arc is a halo of sorts, and it appears when the sun is very high in the sky - higher than 58°. It's typically oriented parallel to the horizon. Often it's only visible in fragments when cirrus clouds aloft are lit with a rainbow of colours. The colours are the result of sunlight passing through the ice crystals that make up the cirrus cloud. The crystals themselves act like a prism, essentially splitting the sunlight into the spectrum of colours.

A massive sinkhole shut down Highway 212 in Damascus Sunday evening, according to the Clackamas County Sheriff's Office.

Reported in the 20200 block of Highway 212, near South Wiese Road, the sinkhole is 20 feet wide by 4 feet deep, transportation officials said Sunday.

According to the Sunrise Water Authority, a water main broke, emptying a 1-million-gallon reservoir. Water service was restored to the reservoir.

Sunrise Water Authority urged customers who lost water pressure or service to boil any water that was used for drinking purposes only. All other uses, such as showers, baths, and watering, are safe, the bureau said. The boil water advisory was lifted Monday evening.

A video showing a rare waterspout in Dangxiong county of China's southwest Tibet Autonomous Region on Saturday has wowed millions of viewers online.

On-site witnesses said that a funnel-shaped rotating waterspout suddenly appeared after the sky was covered by black clouds. The whole process lasted for over ten minutes, Global Times reported.

According to a local meteorologist, the waterspout in Dangxiong was actually a "land tornado", which is a strong wind whirlpool created when the base of the thundercloud reaches to the ground. It usually happens in summer afternoons or dusks when there are thunderstorms.

It is the first time a land tornado has been spotted in Tibet since the autonomous region started meteorological observation in 1961.

The large hole, at the junction of the major commuter route and Beech Street, formed this morning and began at three metres deep and six metres wide.

Throughout the day the hole has continued to grow , as an investigation involving bodies including the council, gas experts and United Utilities gets under way to determine the cause.

John Brown, manager at the Devonshire House Hotel, which is close to the site of the sinkhole, said staff have been told it could be three to four weeks before it is fully repaired.

Montana hit by strongest earthquake in over 20 years, raising concerns that Yellowstone 'supervolcano' is slowly waking up

Following a swarm of over 1100 earthquakes recorded in the Yellowstone caldera over the past month, prompting scientists to voice concerns about a dormant Yellowstone "Supervolcano" slowly waking up, overnight these concerns escalated after a strong M5.8 earthquake hit western Montana early on Thursday morning - the strongest quake to hit the area in the past 20 years - the U.S. Geological Survey reported, with Reuters adding that the tremor was felt hundreds of miles away, from Missoula to Billings and some surrounding states.

The quake appears to be the largest to hit Montana since a slightly weaker M5.6 struck outside of Dillon a dozen years ago. By comparison, the state's largest quake which struck the West Yellowstone region 58-years ago was 7.2 magnitude.

Record amounts of rain have fallen in parts of south-western Japan in recent days.
Almost 500,000 people have been ordered or advised to evacuate their homes in south-west Japan after torrential rain triggered widespread flooding.

Landslides were reported in several areas, and one man was dug out from the mud without signs of life, public broadcaster NHK said.

At least 11 people were missing or could not be reached, including a child, and many more were stranded and calling for help across areas of Fukuoka and Oita prefectures on the Japanese island of Kyushu.

Children and teachers at a school were among those cut off by the floodwaters.

Japan's weather bureau said the amount of rain in the region had broken all records and was continuing to fall.

Parts of Fukuoka prefecture were hit by 774 millimetres of rain in nine hours on Wednesday, more than two times the amount of rain that falls in a normal July, NHK said.

The massive landslides caused by the flooding left at least two houses swept away.

Contrary to what the media is rattling off about above normal temperatures in the Arctic, the Danish Meteorological Institute (DMI) shows that temperatures are record low and just 1C above freezing. Also for the first time ever in history Squaw Valley and Tahoe ski areas will remain open for July 4th skiing and beyond. There is still so much snow up in the mountains that mountain biking and hiking is dangerous because of the still deep snows.
