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.

On 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.

The 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.
