About 17 centimetres of snow fell on St. John's Tuesday night.
St. John's didn't get the full brunt of a storm system that swept across the island on Tuesday night, but high winds are still expected to make a mess of it Wednesday.

About 17 centimetres fell in the capital city and surrounding area. A further five centimetres is forecast to fall throughout the morning on Wednesday, as winds gust up to 90 km/h.

"We probably shouldn't let our guard down because as the day goes on, the wind is going to pick up,"said Environment Canada meteorologist Rodney Barney.

The system was initially expected to bring as much as 30 centimetres to the northeast Avalon, but Barney said the system tracked a little further west.

The brunt of it hit Clarenville and Terra Nova, where roughly 27 centimetres of snow fell.

Storm brings more flooding to Cartagena, Spain - 4th such event in 7 months

The fourth clean-up in 7 months begins in Los Alcázares

The latest heavy storm to cause flooding in Los Alcázares and other towns and villages in the Campo de Cartagena and along the coastline of the Mar Menor was rather less expected than the other three which have hit the Costa Cálida since last September, but the amount of rain it brought with it was very significant indeed in the south-east of the Region of Murcia and in and around the regional capital.

The Aemet national weather summary for Tuesday 24th March makes for very unusual reading in that eight of the ten wettest places in Spain were in the Region of Murcia! Heading the list is the city of Cartagena with 121.2 millimetres, followed by Alhama de Murcia (90.6), Mazarrón (86.6), Torre-Pacheco (84.8), Fuente Álamo (83.0), San Javier, La Manga and the city of Murcia. The top ten is completed by Pinoso in the province of Alicante (Very close to Jumilla in the north of Murcia) and the north African enclave of Ceuta.


Explosive eruption by Shiveluch volcano in Kamchatka, Russia

KVERT recorded one explosive eruption today that generated an ash plume which reached approx. 32,800 ft-49,200 ft (10,000 m-15,000 m) altitude and drifted NW.

The volcano's lava dome remains in a very active state with elevation at 2,500 m.

Ongoing activity could affect international and low-flying aircraft.

It's springtime, and STEVE is back

It's springtime, and STEVE is back. Jocelyn Blanchette photographed the purple ribbon over Fermont, Quebec, on March 22nd. "STEVE was right beside Venus," she says.

STEVE (Strong Thermal Emission Velocity Enhancement) looks like an aurora, but it is not. The phenomenon is caused by hot (~3000°C) ribbons of gas flowing through Earth's magnetosphere at speeds exceeding 13,000 mph. Glowing with a soft-purple hue, these ribbons sometimes appear when Earth's magnetic field is unsettled by the solar wind.

Studies show that STEVE tends to occur more frequently during spring and fall than summer and winter. The onset of northern spring seems to lure the arc out of winter hiding. That means *now* is the time to look for STEVE.

STEVE's usual habitat lies between latitudes +50N and +55N; Blanchette's hometown is located squarely in that range: +53N. Recently, however, sky watchers have been seeing STEVE farther north, as high as +63N. Is STEVE's range increasing?

A 7.2-magnitude quake has struck Russia's Far East region, striking off the Kuril Islands and prompting a tsunami warning for the sparsely populated region.

The quake was felt across the region on Wednesday afternoon local time, with a depth of 56.7km (35 miles). There are no reports of damage or casualties as of yet.

The earthquake triggered a tsunami alert in Hawaii, 5,600 kilometers away, but it was soon called off, with the US National Tsunami Warning Center concluding there was no danger to the small Pacific island chain.

A tsunami warning was also issued for Severo-Kurilsk District of Russia's Sakhalin Region, a local branch of the Geophysical Survey of the Russian Academy of Sciences reported.

Comment: Three days ago Croatia's capital Zagreb was rocked by a 5.3M earthquake, the strongest to hit the city in 140 years.


UrduPoint reports that a small tsunami did indeed strike the northern Kurils:
A magnitude 7.6 earthquake occurred some 500 kilometers (300 miles) from the Russian Far Eastern city of Petropavlovsk-Kamchatsky, the Kamchatka office of the Geophysical Service of the Russian academy of Sciences said.

"Earthquake 14:49 (02:49 a.m. GMT), max magnitude 7.6, total of 463 kilometers from Petropavlovsk-Kamchatsky. The data will be specified," it said.

No casualties or destruction have been reported by regional emergencies services.

There is a risk of tsunami in the North Kuril area after the earthquake, the Yuzhno-Sakhalinsk seismological station's head, Yelena Semenova, told Sputnik.

The authorities said residents were being evacuated on the Kuril island of Paramushir due to the tsunami threat.

Later in the day, the the department of the Russian Emergencies Ministry in Sakhalin island region said that the height of a tsunami wave in Severo-Kurilsk town was 50 centimeters (1.6 feet).

"The tsunami wave with the height of 50 centimeters hit Severo-Kurilsk at 03:15 p.m. local time [04:15 GMT]. There were no preliminary reports about injuries or damage. The threat of tsunami remains, that is why residents of Severo-Kurilsk will stay in a safe area on a hill. Experts will make a decision to cancel the alert after the low tide begins," the statement said.
