Thousands hit by flooding on Sumatra Island, Indonesia

flood
Over 60,000 people have been affected by floods and landslides on the island of Sumatra, Indonesia, over the past few days according to disaster authorities.

The ASEAN Coordinating Centre for Humanitarian Assistance on Disaster Management (AHA Centre) reports that over 52,000 people were affected by floods in northern parts of Medan City, capital of Indonesia's North Sumatra province on 30 March 2021.

The flooding mostly affected areas of Medan Belawan sub-district and was blamed on a combination of heavy rain, high tide and blocked drainage channels. Around 12,335 homes were inundated.

Flash floods and landslides were reported in other parts of the island over the last week.

"Insane depth of cold" to blast Britain in April, as sea ice at both poles continues to grow exponentially

"Insane depth of cold" to blast Britain.

An "insane depth of cold" is set to strike the UK over the Easter weekend, warns the Weather Outlook's Brian Gaze.

Freezing temperatures and frosts will arrive in Scotland on Thursday, April 1, with "polar spring" conditions engulfing the majority of the country by Good Friday.

Looking further ahead, the mercury is expected to sink even lower during the following week, as a violent kink in the jet stream (associated with the historically low solar activity we continue to experience) delivers Arctic air to the lower-latitudes.

Thermometers could sink to -10C (14F) in northern parts, which would topple all-time daily cold records.

The UK's lowest-ever recorded temperature for April 5, for example, is the -9C (15.8F) set in 1990, while 1935's -8.9C (16F) for April 7 could also tumble. In fact, most of the daily benchmarks between early-to-mid April are under threat, including some that have stood for more than a century.

Cascades snow depth running 109% to 167% of normal

Snoqualmie snow
Skiers and snowboarders arrived Monday to fresh snow at Snoqualmie Summit.

"During different times this season it has been the number one snow pack in the county - currently it's over 600 inches (50 feet)at the top of Alpental," said Guy Lawrence, general manager at Summit at Snoqualmie. Fifty feet! That's the height of a 5-story building!

And that will continue growing, because more spring snow is expected.

"Next week we're probably going to get a couple of systems that will bring snow to the higher elevations in the Cascades," said Nick Bond, a professor at the University of Washington and a state climatologist.

6.0-magnitude earthquake hits Fiji region - 2nd major quake in that area of the Pacific Ocean in 5 hours

graph
An earthquake with a magnitude of 6.0 jolted Fiji region at 15:11:18 GMT on Thursday, the U.S. Geological Survey (USGS) said.

The epicenter, with a depth of 597.77 km, was initially determined to be at 21.8731 degrees south latitude and 179.3414 degrees west longitude.

Comment: In the same region of the Pacific Ocean and a little over 5 hours earlier a huge 6.6 magnitude earthquake struck just off the Kermadec Islands.

Thundersnow at Denver International Airport captured on camera

An unusual thundersnow storm moved directly over Denver International Airport on Tuesday night. Thunderstorm is rare in most of the country but does happen with some regularity in Colorado, mainly in the early spring and late fall.

Thundersnow is simply a thunderstorm that occurs when it is just warm enough for a storm but still cold enough for the storm to produce snow instead instead of rain.

Alex Inscoe captured the weather event on video. It shows lightning during a snowstorm which brought half inch of snow to the airport between 10:15 p.m. and 10:45 p.m.

Extensive areas of flooding resulted from the torrential rain, killing one person and forcing thousands to evacuate their homes, dpa news agency reported.

Rainfall that resulted in last month's flood crisis across the Australian state of New South Wales (NSW) was more than double the average, making it the second-wettest March on record, the Bureau of Meteorology (BoM) said on Thursday.

Extensive areas of flooding resulted from the torrential rain, killing one person and forcing thousands to evacuate their homes, dpa news agency reported.

The disaster is estimated to have caused A$2 billion ($1.5 billion) in damage, according to the Australian Financial Review.

Huge 6.6 magnitude earthquake strikes just off Kermadec Islands

AN earthquake measuring 6.6 in magnitude has been recorded north-east of New Zealand, within the so-called Ring of Fire, the USGS has reported.

The tremor is the latest in a a series of 34 in the region in the last day, the USGS has said. It struck at a depth of 6.2 miles. There is currently no tsunami alert in force - but a series of quakes did trigger one earlier this month.

Seismic activity is commonplace in the region, located within the so-called Ring of Fire which stretches around the Pacific Basin.

On Monday, the American Geophysical Union tweeted: "An M8.1 #earthquake off the coast of #NewZealand triggered an estimated 300 #landslides on #RaoulIsland, the largest of the #Kermadec Islands.

Taal Volcano, Philippines records more earthquakes, gas emissions

Taal Volcano (taken October 26, 2020).
TAAL Volcano registered more earthquakes and emitted more gas over the past 24 hours, signs of a looming eruption, the state-run Philippine Institute for Volcanology and Seismology (Phivolcs) said on Wednesday.

Based on the Taal Volcano Network (TVN), 212 quakes, including 168 tremors with durations one to 20 minutes, and 44 low frequency volcanic earthquakes were recorded.

Some 1, 229 tons of sulfur dioxide were emitted by the volcano in Batangas province in the past 24 hours, according to Phivolcs chief Renato Solidum.

Solidum said with the volcano under Alert Level 2, an increased unrest may lead to an eruption and advised "all concerned to remain vigilant".

"The fact that we have volcanic tremors and prolonged background tremor recorded, higher than normal sulfur dioxide emission rate of 923 tons per day, slow but steady inflation of the volcano still indicates magmatic activity at shallow depth beneath the volcano," he said.
