All city snow-clearing equipment, including two plow trucks last used to clear snow after the March 2017 blizzard, has been pressed into action since April 3, the second day of a six-day span that saw 65.6 centimetres of snow fall, with three of those days setting daily snowfall records.
An unprecedented six-day stretch of early April snowfall in Thompson has led to the biggest snow-clearing effort since the blizzard of March 2017 and, with everyone's nerves already frayed as a result of the coronavirus pandemic, harsh words from the city's mayor for citizens "whining" about the state of city roads.

Snow fell in Thompson four of the six days from April 2 to April 7, setting records on three of them. The 15.6 centimetres that fell last Thursday was the most since 6.8 cm of snow in 1995, while the 34.4 cm that fell on Friday beat the previous record of 6.4 cm from 1967 by 28 cm. Only 2.8 cm fell April 4, well below the 1973 record of 8.4 cm, while the 12.8 cm of snow on April 7 was close to double the previous record of 6.5 cm in 1981.

Extreme rainfall has become increasingly common in metropolitan São Paulo, Brazil. The capital of the state of São Paulo is the largest city in the southern hemisphere. The metropolitan area suffered from flooding due to heavy rain in February. Early in the month, no less than 114 millimeters (mm) fell in a single 24-hour period. This was the second highest 24-hour amount for the month since 1943, according to Brazil's National Meteorological Institute (INMET).

According to a study by researchers at the Natural Disaster Surveillance and Early Warning Center (CEMADEN), an agency of the Brazilian Ministry of Science, Technology, Innovation and Communications (MCTIC), both the total rainfall and the frequency of extreme rainfall events in metropolitan São Paulo have increased significantly in the last seven decades.

While there were practically no days with heavy rain (more than 50 mm) in the 1950s, such days have occurred between twice and five times per year in the last ten years in metropolitan São Paulo, according to the authors.

The study was supported by São Paulo Research Foundation — FAPESP under the aegis of its Research Program on Global Climate Change (RPGCC). The findings are reported in the Annals of the New York Academy of Sciences.

Researchers affiliated with INMET, the National Space Research Institute (INPE) and the University of São Paulo's Institute of Astronomy, Geophysics and Atmospheric Sciences (IAG-USP) also took part in the study.

"Intense rainstorms lasting a few hours with huge amounts of water, as much as 80 mm or 100 mm, are no longer sporadic events. They're happening more and more frequently," José Antonio Marengo, a senior researcher at CEMADEN and principal investigator for the study, told.

The Shiveluch volcano in Russia's Kamchatka in the Far East has spewed ash as high as 10 km above sea level on Wednesday, the Kamchatka Volcanic Eruption Response Team (KVERT) said.

"The column of ash rose 9.5-10 km above sea level. According to KVERT's satellite data, the ash cloud spread nearly 45 km to the south and south-east from the volcano toward the Kamchatka Bay," KVERT said.

Volcanologists say that Shiveluch's explosive-extrusive eruption continues. The volcano may spew ash again as high as 10-15 km above sea level at any moment.

The Shiveluch is the northernmost active volcano on the Kamchatka Peninsula. It is located in 50 km from the Klyuchi settlement with around 5,000 residents. The Shiveluch is 3,283 meters high and around 60,000-70,000 years old. The volcano has been erupting since spring 2009.

A deadly Pacific storm slammed Fiji on Wednesday, tearing off roofs and flooding towns in the capital Suva days after the category-five cyclone hit the island of Vanuatu.

Cyclone Harold passed over Fiji's south at about midday, levelling homes and snapping communications links in the archipelago, which has adopted curbs on the movement of people to rein in the coronavirus.

"We've seen reports of injuries," Vasiti Soko, the director of the National Disaster Management Office (NDMO), said by telephone.

"As to the number, as well as the intensity, of the injuries, that's yet to be ascertained."

100% fruit losses in many parts of central Europe and the Balkans

Poland frosts
One of the coldest April mornings in decades.

2 Apr 2020 - With temperatures dropping below -5 °C (even to -8 °C in some valleys) during the time of blossoming trees, the damage is almost complete - 100% in many vineyards and fruit plantations.

There are numerous reports of destructive frost to the fruit trees (cherry, peach and almond orchard) and some other crops across Slovenia, northeast Italy, Croatia, Serbia and Hungary.

Frosts will not stop in Italy - 100% damage to some fruit crops

frost
The wave of night frosts that are affecting much of Italy goes on. In the north, the situation has reached an unprecedented level, with 8 hours below zero on the night of April 2 and minimum peaks of -6 °C. Even the anti-frost systems are struggling, because protecting an orchard with 5 °C below zero is not easy.

After three sleepless nights operating the anti-frost system, Davide Vernocchi, president of Apo Conerpo, is dispirited: "With these temperatures, this defense system is in crisis. We are talking about 5, 6 degrees below zero in some areas of the province of Ravenna. Apricots, peaches, plums, kiwis: in some cases, the damage is of 100%. There will be less work for everyone. Nature has cruelly solved one of our great concerns: the lack of manpower. Paradoxically, several farmers in the next few months will have to go looking for work somewhere else".
