flood peru
Days of heavy rain triggered flooding and mudslides in Arequipa department in southern Peru.

The heavy rain began around 13 March, 2020, causing rivers and streams to break their banks, triggering mudslides and flooding.

Among the worst hit are areas in the north of the city of Arequipa, where streets were swamped in water, mud and debris.


Media report that at least 100 homes have been damaged and a bridge in the north of the city is in danger of collapse.

Residents in Sachaca district were asked to move away from a local stream that had broken its banks.

The National Weather Service issued two rare tornado warnings for western Hawaii on Tuesday morning, the first tornado warnings for the state in over a decade. The storms resulted in no reports of damage, but the threat for stormy weather and flash flooding will continue across the Hawaiian Islands for the next couple of days.

The first tornado warning went up for the island of Niihau just before 1:30 AM Tuesday local time, followed by a second for Kauai around 6:00 AM local time.

The most serious of the two thunderstorms affected southern Kauai. The National Weather Service in Honolulu issued a severe thunderstorm warning for southwestern Kauai before the storm came ashore, warning residents that damaging wind gusts up to 60 MPH were possible. The storm began to take on some characteristics of a supercell, complete with a hook-like appendage that began rotating as it approached shore. A nearby radar site showed strong low-level rotation that prompted the tornado warning. The rotation quickly dissipated once the storm came ashore near Kaumakani just after 6:00 AM. There have been no reports of damage so far.

Indian Army rescues 560+ stranded civilians amid heavy, record breaking snowfall

Record snow in India
Over the past week, the Indian Army has airlifted some 600 stranded civilians from Sela Pass and Gurez following months of intense snowfall and sub-zero temperatures.

The entire Gurez Valley has been cut off from Kashmir since early November, 2019 due to exceptionally heavy snowfall, with snow-clearing efforts along the key Razdan Pass -which connects Bandipora to Kanzalwan- not expected to be completed until the end of April.

On March 14, the Dawar Battalion of Snow Leopard Brigade received a request from the civil administration to evacuate 160+ civilians stranded in the "cut-off" Gurez and Bandipora regions.

The operation lasted hours amid record-breaking snowfall, reports republicworld.com — and key to its success was the immediate medical support given to critically-ill patients suffering from the cold.

Saturday's evacuation of 160+ people came just days after March 8th's efforts to save 390+ stranded at Sela Pass in Tawang district, again due to record-breaking snowfall.

"The rescue operation was carried out at an altitude of 14,000 feet on the nights of March 7 and 8," Tezpur based Defence Spokesman Lt Col Harsh Wardhan Pande said. Those rescued were again provided with "immediate medical support" as well as "hot snacks".

India's record snowfall has contributed to the staggering accumulations across the Northern Hemisphere this season — levels are currently some 500+ gigatons above the 1982-2012 average:

The weather in Iceland remains turbulent this week and the Westfjords region is worst affected. There is an orange weather warning in effect and the north-easterly storm with heavy snow will continue into tomorrow. The orange warning remains in effect until 20.00 this evening.

The Coastguard vessel Týr is arriving in Flateyri as a precaution, as the village is on avalanche alert; as is Patreksfjörður. Some residential properties in both communities have been evacuated as a precaution, and some industrial buidlings in Ísafjörður have been evacuated for the same reason.

According to the Icelandic Met Office, there has also been a strong easterly wind affecting the north and east, with significant precipitation in East Iceland. South Iceland has gentler southerly winds with scattered sleet and rain showers but plenty of sunshine in between.

Tropical Cyclone Herold
© NASA WorldviewOn March 16, the MODIS instrument that flies aboard NASA’s Aqua satellite took this image of Tropical Cyclone Herold and showed a well-developed hurricane with a visible eye.
Tropical Cyclone Herold swept over Madagascar, bringing winds of more than 140 km/h and heavy rain from 13 March, 2020. Severe flooding was reported in north-eastern areas of the country, where 4 people have reportedly died.

Herold formed on 13 March 2020 as Tropical Cyclone 22S and was later renamed Herold once it had intensified into a tropical storm.

Heavy rain from the storm caused flooding in Sava and Analanjirofo Regions in Madagascar. At least 4 people are thought to have died.

Disaster authorities said initial assessments showed that over 3,000 people have been affected in the district of Maroantsetra in Analanjirofo Region and Sambava and Antalaha districts in Sava Region. Flood water reportedly reached up to 2 metres in some areas, damaging around 500 homes.

Late winter storm continues in Sierra Nevada - dumps up to 4 feet of new snow

The Sierra snowpack has been boosted over the last few days.
© Mike PeronThe Sierra snowpack has been boosted over the last few days.
After a slow wet season without much precipitation, the Sierra Nevada mountain range region in California is finally starting to see some heavy snow.

AccuWeather Senior Meteorologist Alex Sosnowski said parts of the central and northern Sierra Nevada were buried under somewhere between 1-4 feet of snow since it started falling on Sunday. The Sierra Nevada Mountains are usually pummeled with "yards and yards" of snow in the winter, and this snowfall is helping that area make up for a long drought.

"There have probably been periodic blizzard conditions, but most places were below that criteria," Sosnowski said. Blizzard criteria are reached when a storm sustains winds or wind gusts of 35 mph or greater, and the visibility diminishes to less than one-quarter of a mile for three consecutive hours.


Comment: Immediately prior to this latest dump up to 38 inches of snow in 24 hours hit the region.
