Despite summer's rapid approach, parts of the nation have been blanketed by record-breaking snowfall.

Residents of Hobart in Tasmania shivered through their coldest night since 1953 on Sunday night when the mercury fell to just 2.9 degrees.

Up to 300mm of snow was also dumped over the Huon Valley.

Conversely, it follows the state's record-breaking winter, which saw the warmest daily temperatures in 33 years.

Meanwhile, on the mainland, in Victoria's Grampians region a dusting of snow was visible throughout the weekend and into Monday morning.

As if last week's wild weather wasn't enough, days of nearly ceaseless heavy rain and high winds prompted extensive flooding and mudslides Monday, forcing evacuations, school and road closures and a state of emergency declared in 14 Western Washington counties.

The weekend's heavy rains stemmed from the Pineapple Express, also known as an atmospheric river. The National Weather Service issued a flood watch for portions of northwest and west-central Washington, including King, Pierce and Snohomish counties.

NWS issued a wind advisory warning of southwest winds between 15 and 30 mph with gusts up to around 40 mph in Seattle, Bremerton, Tacoma and areas of the Hood Canal. The strongest winds, with gusts of up to 60 mph, were near the Strait of Juan de Fuca and the shorelines of Snohomish, Skagit and Whatcom counties thanks to a cold front passing through the region.

More than 158,000 customers were without power in Western Washington at one point Monday afternoon.

M3.1 earthquake shakes Scotland, first tremor felt in Ireland since 2019

Residents of western Scotland received a bump in the night after an earthquake shook the region in the early hours of Tuesday.

A quake with a magnitude of 3.1 occurred shortly before 2am with its epicentre 11 miles north-west of the town of Lochgilphead, 88 miles north-west of Glasgow, the United States Geological Survey (USGS) said.

More than 30 people reported to the USGS that they had felt the tremor, with reports coming from as far as Edinburgh and Ballycastle in Northern Ireland.

Comment: The BBC provides some additional info that reveals quakes of this kind don't happen that often:
Rosemary Neagle, who lives on a farm in Kilmartin Glen near Lochgilphead, said the noise of the tremor was so loud that she initially thought something had exploded in one of her sheds.

She told BBC Radio's Good Morning Scotland programme: "It kept on intensifying and the house vibrated. It rumbled on for about 10 seconds afterwards, so it was quite frightening.

"I have experienced them before here but never to that extent. The house has never shook like that in the past."

The overnight earthquake registered on all the seismographs across Ireland.

Dr Martin Möllhoff, director of Seismic Networks in Dublin, said it was the first felt earthquake that had been anywhere in Ireland since one was recorded close to the Irish border in County Donegal in 2019.

"It is a little bit exciting because this does not happen so often and most people think there are no earthquakes in Ireland," he said.

This home in Levittown, New York was damaged in Saturday’s tornado touch-down.
The National Weather Service has confirmed that 9 tornadoes touched down across portions of New York, Connecticut, and Rhode Island on Saturday while a waterspout was observed off the Jersey Shore as severe weather moved through the region. Since 1950, there was never a tornado recorded in Connecticut or Rhode Island in the month of November; 2021 clearly shatters that record.

The National Weather Service uses the Enhanced Fujita Scale to classify tornadoes. Weak tornadoes of 65-85 mph are rated EF-0 while weak tornadoes with winds of 86-110 mph are considered EF-1. A EF-2 with 111-135 mph is considered strong, while an EF-3 with winds of 136-165 mph is also considered strong. EF-4 and EF-5 rated tornadoes are considered violent; EF-4 has winds of 166-200 mph while EF-5 has winds in excess of 200 mph.

Flooding in Merritt B.C., early in the morning of November 15, 2021.
Flooding has forced the evacuation of the entire community of Merritt, B.C.

On Monday morning, the city announced an evacuation order had been issued.

Residents were being asked to stay with friends or family if possible, or to go to the Emergency Social Support reception centres in Kamloops and Kelowna.

"The flood waters have now inundated two bridges across the Coldwater River, and flood waters prevent access to the third," the city said in a statement.

"High flood waters have rendered the City's Wastewater Treatment Plant inoperable for an indefinite period. Continued habitation of the community without sanitary services presents risk of mass sewage back-up and personal health risk."

U.S. Coast Guard evacuates flooded RV park at Oregon Coast
Downpours across northwestern Oregon, particularly in coastal communities in Lincoln and Tillamook counties, saw severe flooding Friday. Swollen rivers blocked roadways, threatened homes and trapped people.

At least two RV parks — one in Neskowin and one in Otis — were flooded and evacuated Friday morning. U.S. Highway 101 is seeing slow travel due to high water.

High water prompted the closure of Highway 18 at milepost 1, near the interchange with Highway 101 outside Otis.

Numerous rivers and creeks reached minor flood stage on the northern Coast, including the Siletz, Nestucca, Salmon, Trask and Wilson rivers. The rivers appeared likely to crest Friday afternoon before dropping Friday night and Saturday, according to National Weather Service river gauges.

NWS said that in the past 24 hours, Tillamook and Lincoln counties have received between 2.77 and 4.04 inches of rain.
