Why a Full Moon Could Make This Weekend’s Blizzard More Destructive
January 21, 2016 - Supermoon
All signs are indicating toward a record blizzard attack a D.C. Metro area this weekend, and a snowpocalypse chaos is already environment in. To make a imminent meteorological blockbuster even some-more ominous, Jonas is going to coincide with a full moon. Quick, scapegoat a goat!
Now, a Moon gets blamed for a lot of things that it unequivocally has zero to do with (births, werewolves, ruthless rages), and we’re not perplexing to calumniate Earth’s nearest neighbor. But one Earthly matter a Moon does change is a tides. As Gizmodo’s Ria Misra pointed out yesterday, a full moon means aloft coastal tides. Pair that with hurricane-level breeze speeds this weekend, and we could be in for some critical flooding.
The tides are caused by a total gravitational yank of a Sun and a Moon on a Earth. Full moons start when a Sun, Moon and Earth are ideally aligned, with a Earth in between. When this happens, it causes a clever gravitational tug-of-war and a many impassioned tides of a month—the tip highs and a lowest lows. High waves during a full moon is typically one to dual feet aloft than it is during other tools of a lunar cycle.
Normally, a monthly lessen and upsurge of a tides does us no harm, though when a full moon happens to coincide with stormy conditions, things can get a bit messy. We saw an impassioned instance of this final September, when climactic and astronomical army total to move us a supermoon and a pleasant charge (Hurricane Joaquin) during a same time. (A supermoon occurs when a Moon is full during perigee, a closest proceed to a Earth.) The outcome was some pretty epic flooding on both sides of a Atlantic.
This time around, we’ve usually got a unchanging full moon to contend with, though winter charge Jonas is earnest extreme winds, with tip speeds adult to 40 to 50 miles per hour along a Delaware and Jersey shores. According to Bob Henson, a meteorologist and blogger with Weather Underground, we saw a identical unfolding play out over a decade ago, when a President’s Day II storm struck a northeast.
“This is not too opposite from a 2003 storm, that also happened during a full moon,” Henson said, observant that a storms had somewhat opposite marks though were of identical magnitude. The 2003 charge caused between 8 and 9 feet of flooding along a Jersey shore—which lines adult really closely with a National Weather Service predictions for this weekend.

There is a china lining: a flooding this weekend could be even worse if a fixing of a charge and a tides was somewhat different. “This weekend, a morning high waves is higher,” Henson said. “The full moon is adding about dual feet to a morning waves and a feet to a afternoon. That’s a good thing since a tip charge swell will substantially be Saturday night.”
The Moon will arise around 5 pm Saturday and will be full by 8:46 pm. If we have any rite rituals to keep a Moon from messing with your life, now would be a good time to do them.
