Earth Changes
Some 3,000 firefighters were battling several blazes with triple-digit temperatures recorded in valleys and inland areas.
A wildfire in the Sierra Nevada foothills north of Sacramento was only two percent contained by early evening and had destroyed 10 homes, scorching 2,000 acres (800 hectares) of forest and sparking evacuations and road closures.
The California Department of Forestry and Fire Protection (CalFire) said five residents and a firefighter had sustained minor injuries.
Meanwhile a blaze that forced evacuations in San Luis Obispo County tripled in size from Saturday morning to 19,000 acres by the evening. Fanned by hot, dry winds, it was just 10 percent contained, CalFire said.
Some 17 wildfires in various states of containment were burning in California Saturday, from the Six Rivers National Forest in the north to the San Bernardino Forest east of Los Angeles.
An excessive heat warning has been extended until 11:00 pm (0600 GMT) for much of southern California, with temperature records being broken across the region.

Think of Yellowstone as a gigantic pressure cooker, fueled by a massive supervolcano. Water from rain and snowmelt, much of it centuries-old, percolates through cracks in the Earth's crust until heated by molten rock reservoirs deep below. The water then filters upward, eventually finding release in the thousands of geysers, hot springs, and other hydrothermal wonders.
More than 1,800 firefighters were fighting around 200 fires on Saturday, many of which are considered to be out of control. Another 260 firefighters were coming to help from across Canada.
Official province-wide evacuee numbers have not been released; however an estimated 6,000 people had been forced from their homes as of Saturday afternoon, according to the Cariboo Regional District.
Evacuation orders have been issued for the communities of:
Ashcroft
Cache Creek
Princeton
105 Mile House
108 Mile House
150 Mile House
MetService duty forecaster Tuporo Marsters said the city was struck by 701 flashes and rocked by loud, rolling thunderclaps.
The dangerous storm swept across the city at rush hour, grounding flights, flooding homes and shops, and leaving roads knee-deep in water.
Spectacular footage has also emerged on social media capturing the moment a lightning fork struck the top of the city's tallest building.
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.
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.
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.
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.

The wildfires temporarily trapped at least 90 children and some 50 councilors at a local summer camp, Zaniboni said, adding that later the campers had been safely evacuated.
On Saturday, the blaze dubbed the Alamo Fire burned more than 23 square kilometers outside Santa Maria and remained 10 percent contained, Zaniboni added. The Santa Barbara blaze is one of three separate wildfires that have rocked California.
Some 300 residents were to evacuate Santa Barbara and neighboring San Luis Obispo County, AP reported.
