A winter storm dumped up to nearly 20 inches of snow in northern Arizona on Sunday with the Flagstaff area getting between 12 and 18 inches of snowfall, according to the National Weather Service.

With more snow expected Monday, Northern Arizona University announced it was canceling all classes Tuesday on the Flagstaff Mountain Campus due to the storm.

But school officials said classes held at other NAU locations, including online, will meet at their regular time and place.

Arizona Department of Transportation officials said multiple closures were in place Sunday for State Route 64 in the Grand Canyon area and northbound State Route 89 near Sedona through Kachina Village.

“We have 200 snowplows statewide that are working around the clock to get the roads clear,” said David Woodfill, an ADOT spokesman. “Before these storms, we’re always out ahead of time, prepping the roads with de-icing material.”

Around the Southwest, mountainous areas west of Las Vegas, northern New Mexico and other mountainous areas also were expected to see heavy snowfall during the holiday weekend.

The National Weather Service predicted up to 11 inches of snow in Chama, although most of northern New Mexico will see far less.

The U.S. Department of Energy announced a conditional loan of $700 million to an Australian mining company to pursue a lithium project still facing environmental hurdles in Nevada as the U.S. seeks domestic supplies for a key component in electric vehicle batteries.

The move ups the ante in what’s already a high-stakes battle over President Joe Biden’s energy agenda and conservationists fighting to protect an endangered wildflower found only at the proposed mine site on a high desert ridge halfway between Reno and Las Vegas.

Ioneer Ltd. has hoped to begin mining at Rhyolite Ridge by 2026 in Esmerelda County.

The Energy department said the site could produce enough lithium to support production of about 370,000 electric vehicles annually for decades.

More rain and snow fell during the weekend in storm-battered California, making travel dangerous and prompting new evacuation orders over flooding concerns along a swollen river near Sacramento.

Bands of thunderstorms with gusty winds started Saturday in the north and spread south, with yet another atmospheric river storm following close behind Sunday, the National Weather Service said.

Up to two inches (5 cm) of rain was predicted for the saturated Sacramento Valley, where residents of semi-rural Wilton, home to about 5,000 people, were ordered to evacuate as the Cosumnes River continued to rise.

Another three inches (7.6 cm) of snow and gusty winds were expected in the Sierra Nevada. Interstate 80, a key highway from the San Francisco Bay Area to Lake Tahoe ski resorts, reopened after being closed most of Saturday because of slick roads, snow and whiteout conditions.

The University of California Berkeley Central Sierra Snow Lab tweeted Sunday morning that it received 21.5 inches (54 centimeters) of snow in 24 hours.

Its snowpack of about 10 feet (3 meters) was expected to grow several more feet by Monday.

A backcountry avalanche warning was issued for the central Sierra, including the greater Lake Tahoe area, through Monday.

The Dumont d’Urville Station is a scientific research station that belongs to the French Republic, and it is located on Île des Pétrels, which is part of the Géologie Archipelago in the claimed territory of Adélie Land in Antarctica.

Named after the French explorer, naval officer and rear admiral, Jules Dumont d’Urville, it was opened officially on 12 January 1956, where the research station nowadays is operated by the joint operation of French public and para-public agencies, French Polar Institute Paul-Émile Victor.

As the station covers an area of about 5,000 square m (53,820 square ft), there are between 20 to 30 persons accommodated between March and November, or when it is the overwintering.

The entire facility is comprised of comprehensive scientific observatories with about 50 installations, among which the most notable and important are the living quarters for the staff and the laboratories for biology, geophysics, and meteorology.

Dumont d’Urville Station is also used as part of the transportation route for supplies of the Italian Concordia Station which is further 1,100 km (684 mi) in the interior of the continent.

Still, this French scientific facility is playing an important role in the understanding of the climate, in addition to the wildlife that is blossoming in the area.

From the fauna, the Emperor penguins are the most common sight in the vicinity of the station, nevertheless, the Adélie penguin is too present as they are using the rocks around Dumont d’Urville as a refuge to reproduce.

There is even a large population of birds, especially skua, snow petrel, giant petrel and Cape petrel who are returning every year when the temperatures are a bit higher than the usual ones.

All in all, this year round open research facility is an interesting feature from the cold continent of Antarctica, giving every visiting scientist an interesting perspective about how the life on the planet has changed and how we are the ones making that change.

As some schools re-open across California, the scale of the damage caused by a once-in-a-generation deadly “parade of storms” is becoming clear – as well as the major clean-up effort that will be required for residents of all ages.

Many schools in central and northern California cancelled classes shortly after the start of 2023 as road conditions became impassable due to downed trees, landslides, floods and snow.

But even as the foul weather continues into a third week, pupils further south are now back in school as officials forecast that the worst of the continuing storms may be over.

In Santa Barbara County, where the exclusive community of Montecito was evacuated due to fears of mudslides, the school district resumed classes for most pupils on Wednesday – one day after Montecito’s order to flee was lifted.

On social media, parents fretted about whether pupils commuting to school – navigating through work crews repairing damages -would be penalised for lateness or absence.

Fort Christian is a historic colonial fortress built in the capital city of the Virgin Islands of the United States, Charlotte Amalie.

Considered to be built between 1672 and 1680, it served a great purpose for defense and governing of the island during the entire period of the Dano-Norwegian rule of the islands, which later was only a Danish rule.

Designed by Governor Jørgen Iversen, it originally occupied a narrow peninsula that jutted south into the harbor, which was basically a square structure with stone curtain walls and diamond-shaped stone bastions at the corners.

The first attempt to settle on the island was unsuccessful due to the Second Anglo-Dutch war when there were plenty of raids, where later Governor Iversen lead the second expedition, which was this time successful.

He landed on the island in 1672, and began with the plans of building this fortress which was named after the Danish King Christian V.

In the past, there was a circular stone tower in the center which was torn down in 19 century and replaced by the present Gothic Revival structure, and in addition to the three of the curtain walls and the four bastions that remain today, there are also some living quarters built along the surviving curtain walls.

Designated as a National Historic Landmark in 1977, it is the oldest building in continuous use on the islands which was from governor’s residence, to a a place of worship, a police station, to become what it is today, a museum. Most likely the most interesting part of the fortress is the colorful Victorian Clock tower which was added at one of the entrances with the expansion of 1874.

As there are constant reconstructions to the museum, Fort Christian is one of the biggest landmarks of the US Virgin Islands, and all of the visitors to the islands are witnessing the impressive and great colonial history that occurred in the capital.
