Large sinkhole opens in Winter Garden, Florida neighborhood

Residents in an Orange County neighborhood said a sinkhole opened up near their homes.

The hole forced crews to shut down a road in the Orchard Hill subdivision on Cypress Hill Road, not far from State Road 429.

Residents said the hole was filled with dirt and it's not blocked by barricades.

"It's pretty scary. We don't want it to spread," said Heather Kelly.

Kelly and her family live feet away from what the county calls an active sinkhole. "It's a lot wider now than it was in the first place," said Kelly.

Residents said the sinkhole was 6 inches deep and, before it was filled, it had grown to a depth of 12-feet.

"We're always concerned. This is a new home. We've been here for about a year," Kelly said.

Huge amounts of snow, up to 8 m, at Mt Gassan, Yamagata prefecture, Japan over the past few days.
Go to this link to see pics. of up to 26.2 feet of snow on the ground in Japan. This is near Mt. Gassan, which at 6,509 feet above sea level is not a terribly high mountain. Very cold air coming off Siberia can produce incredible ocean-effect snow there. And check out these pictures of gigantic snowcover in N. Japan. I think the pics. at this second link are from 2012. Looks like the sun is fairly high in the sky in these pics.

8.2% of the U.S. has a snow cover - mostly out West, but also in northern Maine and northern N. Dakota.

Most of Canada is still snow covered and the lakes are frozen (except near the U.S. and western British Columbia).

This is Northern Hemisphere snow extent, which been increasing a little over the past couple decades (pic. from Rutgers Snow Lab).

Mountain snowpack well over average in Northwest Montana


A plow clears snow from Going-to-the-Sun Road in Glacier National Park earlier this month.
The higher elevations of Northwest Montana can expect another round of winter-like weather this week, adding to a mountain snowpack that remains well above average for this time of year.

As of Tuesday, the snowpack in the Flathead River basin was at 120 percent of normal. The Kootenai River basin boasts snow totals 113 percent of average, while the Upper Clark Fork basin is at 108 percent.

"We still have a lot of snow in the high elevations," said Ray Nickless, a hydrologist with the Weather Service in Missoula. "And it continues to build. We certainly have a lot of water still to come down this spring."

Nickless pointed to a weather station at Flattop Mountain at 6,300 feet in Glacier National Park. The site shows more than 10 feet of snow on the ground, holding about 52 inches of water.

Surprise snowfall in the heart of France

It snowed Tuesday night in the northern Côte-d'Or! Snowflakes begun falling around 19:30 in the Saulieu area, leaving a light white coat covering the landscape as shown by photographs taken shortly before 20:30.

The snowfall could continue for a few hours since Météo France forecast some flakes for parts of the department (Etalante, Vitteaux, Saulieu, Arnay-le-Duc) early on Wednesday.

Is the Tahoe Glacier making a comeback?

This is not as far-fetched as you may think. In fact, if history is any guide it is inevitable. Not only inevitable, the process may have already begun.

California's Squaw Valley ski resort, just west of Lake Tahoe, has been buried beneath more than 58 feet of snowfall this season. That's enough snow to completely cover a five-story building. With such copious amounts of snow, Squaw Valley CEO Andy Wirth announced last week that some ski trails may stay open all summer and into next season.

In other words, the snow may not entirely melt this summer. I don't know if Mr. Wirth fully understood the import of his words, but readers of this website ( iceagenow.info ) certainly do.

"Isn't this how glaciers are formed?" asked one reader. "Snow in one year still existing the following year?"

"Golly! Wouldn't that start a glacier?" asked another.

"Ski all Summer thru Fall? That's called a glacier," exclaimed yet another reader. "Glaciation of the Sierras."

Those readers are correct. That is indeed how glaciers form. That is also how ice ages begin - not because some huge ice sheet starts grinding southward (or northward if coming from the bottom of the globe), but because the more the snow accumulates, the less chance it has to melt.

An "extraordinary" collapse in temperatures, up to 15 degrees C in northern areas.

25 Apr 2017 - Galicia will be this cold and, during the next 48 hours in the province of Lugo, the low will vary between 0 and 3 degrees.

At night, Vitoria and almost all the provinces of Castilla y León will ​​range from 2 below zero to 2 degrees.

On Thursday night there will be frosts in the northern highlands. Leon will fall to 4 degrees below zero.

The cold ​​will cause significant snowfall in the north, especially in the Cantabrian mountain range and the Pyrenees, and will occasionally affect flat northern areas above 600 / 1,000 meters on Wednesday and Thursday.

Yellow alert: In Asturias there is yellow alert for snow in the Cantabrian mountain range and the Picos de Europa at 900 meters, which is expected to fall to 600 meters tomorrow.

From tomorrow, the snow will affect Huesca, Barcelona, ​​Girona, Lérida and Asturias. On Thursday the snow will remain in Teruel, Barcelona, ​​Gerona and Lleida. Efeverde

Local fishermen have reported an increase in tropical fish caught just off Perth beaches over the past week.

According to Recfishwest, many Perth fishermen had reported landing tropical fish off the coast in unusual spots.

"We've been receiving some reports of uncharacteristic tropical fish caught just out of Perth the last week," a spokesperson said.


"Both north and south have seen rare catches which is exciting for the fishing community."

Most notably, Perth locals have reported landing a rankin cod out of Mindarie, and a large red emperor off Rottnest Island in the last week.

Three hikers killed by lightning bolt in Java, Indonesia

On April 23, 2017, three hikers on Mount Prau in Central Java died after being struck by lightning. The unfortunate incident occurred when a group of 11 people hiked from their base camp at Patak Banteng and decided to spend the night on Mount Prau.

The next day, the group decided to go down into the valley due to heavy rain on top of the mountain. They pitched their tents near the mobile signal transmitter tower. Not long after, lightning struck their location, killing three members of the group.

After the incident, one of the survivors said the strike may have been triggered by one of the hikers who opened his mobile phone after detecting a signal in the area.

In addition to three fatalities, the lightning strike caused severe burns to six of the hikers and minor burns to two of them. Those who died were identified as private sector workers named Deden Hidayat Maulana (31) from West Java, Aditya Agung Darmawan (30) from East Jakarta and Adi Setiawan (31) from East Jakarta.

Floods in Manoguayabo, Santo Domingo, April 2017.
Flooding has caused major problems in at least 5 provinces in the Dominican Republic after staggering amounts of rainfall over the last few days.

According to the country's meteorological office (ONAMET), almost 400 mm of rain fell in 24 hours in Barahona between 22 and 23 April, 2017. Further heavy rain has fallen since, mostly in southern areas of the country.

In their latest report of 25 April, the Emergency Operations Centre (Centro de Operaciones de Emergencias - COE) says that flooding has affected several areas in Santo Domingo, San Cristóbal, Monte Plata, Sánchez Ramírez, Duarte and Barahona provinces. Several rivers have overflowed, including the Ozama, Yuna, Cevicos, Manoguayabo and Haina.

As many as 3,429 homes have been damaged or affected by the flooding, with around 9 houses completely destroyed. Emergency services and military have rescued 153 people.

Föhn winds: New insight into what weakens Antarctic ice shelves

New research describes for the first time the role that warm, dry winds (katabatic winds) play in influencing the behaviour of Antarctic ice shelves. Presenting this week at a European conference scientists from British Antarctic Survey (BAS) explain how spring and summer winds, known as föhn winds, are prevalent on the Larsen C Ice Shelf, West Antarctica and creating melt pools. The Larsen C Ice Shelf is of particular interest to scientists because it of the collapse of Larsen A in 1995 and Larsen B in 2002.

The researchers observed the föhn winds, which blow around 65% of the spring and summer period, extend further south and are more frequent than previously thought, and are likely to be a contributing factor that weakens ice shelves before a collapse. The results are presented this week (Tuesday 25 April) at the European Geosciences Union General Assembly (EGU) in Vienna.

In 1995 and 2002, the Larsen A and B ice shelves collapsed, depositing an area the size of Shropshire into the Weddell Sea. Whilst ice shelf collapse doesn't directly contribute to sea level rise, the glaciers which fed into the ice shelves accelerated, leading to the loss of land ice, and subsequently indirect sea level rise. The processes responsible for the collapse of these ice shelves were largely debated, and it is now thought that crevasses on the ice shelf were widened and deepened by water draining into the cracks. Föhn winds are thought to be responsible for melting the ice shelf surface and supplying the water.
