Snow cover analysis of the Lower 48 states early Sunday morning. In the South, sleet accumulations are shown in some areas.
An analysis of snow cover across the Lower 48 showed that only Florida had no snow or ice on the ground Saturday into early Sunday morning, according to the National Operational Hydrologic Remote Sensing Center (NOHRSC).
It should be noted that in this depiction of snow cover, sleet accumulations may be shown as well. This is the case for parts of the South after Winter Storm Helena.
The NOHRSC analysis says that 66.4 percent of the Lower 48 was covered by snow or ice as of Sunday morning. That's the highest coverage so far this winter season in the U.S.
Some of the deepest snowpack across the nation was in the northern Plains, Great Lakes snowbelts, northern Maine and the mountain West.
If you are wondering about Hawaii, yes, there was snow on ground there too. This satellite image shows the snow-capped volcanic peaks of Mauna Kea and Mauna Loa on the Big Island on Saturday.
The quake was detected at 5:47 pm, with its epicentre located in the Barrow Strait waterway. It was initially measured at magnitude 6.4 before being downgraded.
There are no reports of deaths or casualties at this time.
An Earthquakes Canada seismologist told Global News that there is likely little cause for major concern given the distance of the epicentre from Resolute.
"I would expect the damage to be pretty minor, if there was any," Nick Ackerley said.
Resolute has a population of around 240, and is the second most northerly community in Canada.
The last earthquake to hit the Barrow Strait occurred in December 1987, and was measured at a magnitude of 5.4.
