An Arctic surge will bring bitter cold air to the Northeast this weekend, with record low temperatures expected.
About 20 cities across the East endured record-breaking cold Sunday, forecasters say.
New York City's temperature plummeted to 1 below zero at Central Park, shattering the record of 2 degrees, set during World War I.
Boston reported 9 below. Toronto's temperature reached 16 below over the weekend.
And those are just the real temperatures.
Factor in strong winds, and states from northern Pennsylvania to Maine felt wind chills well, well below zero.
In all, more than 75 million people from the Midwest to the Eastern Seaboard are expected to be affected by snow and freezing rain into Tuesday.
New York City Mayor Bill de Blasio urged residents to brace for dangerous conditions.
"The city is facing some of the coldest temperatures and wind chills we've seen in the last 20 years," de Blasio said. "Extremely cold weather can be life-threatening -- especially for seniors, infants and people with medical conditions."
The mayor thanked first responders.
"I think, the combination of the way New Yorkers have heeded the warnings, and the fact that our first responders are out constantly scanning for anyone who might need help, it's been very effective. And thank God, we have no reports to date of any fatalities," he said.
Comment: Unusual migratory patterns and deaths of sea creatures around the world seems to be increasing:
- North Sea sperm whale death toll increases to 23 as another 8 are washed up on German coast
- 300 turtles and a bottlenose dolphin found dead on beach in India
- Tens of thousands of dead jellyfish and starfish found on beaches of West Sussex and Hampshire, UK
- Rare deep sea ragfish found dead on coast of Gustavus, Alaska: 4th for the state in 3 years
- Wrong time, wrong place: Rare Arctic Beluga whale seen off the Irish coast
As the number of volcanoes erupting right now is greater than the 20th century's YEARLY average, a comparable escalation in activity of their underwater counterparts seems logical.It is estimated there are up to one million submarine volcanoes on our planet. Effects from this volcanic activity, combined with increased methane outgassing, radiation from the Fukushima disaster are probably also causing the ongoing devastation of marine life, mass fish die offs and strange migratory behaviour we are currently witnessing.
