A storm system causing severe weather Sunday along the Gulf Coast is forecast to move off the East Coast, turn into a nor'easter and threaten the Northeastern United States on Monday night into Tuesday.The storm's exact path remains a bit uncertain, but the system will bring precipitation and wind in what will be the third significant winter storm in the past 10 days.A winter storm watch is in effect for 8.5 million people in New England, including residents of Boston and Portland, Maine. The National Weather Service Boston estimated 6 to 8 inches of snow for parts of Massachusetts, Rhode Island and Connecticut.New York, Philadelphia and Washington are only under a hazardous weather outlook at this time. The next forecast update will come at 8 p.m. on Sunday.The American model forecasts heavy snowfall for areas of New England and upstate New York, whereas the European model shows less snowfall. Still, both models agree there will be more snow on the way for the Northeast.If the nor'easter tracks closer to the coast, then stronger winds and coastal flooding may become issues as well.Last weekend, a powerful nor'easter that morphed into a "bomb cyclone" slammed much of the Northeast with heavy snow and rain, hurricane-force wind gusts, and significant coastal flooding. The storm left six people dead from falling trees, and about 900,000 people lost electrical power.As residents were still digging out from that snow, a second storm hit the Northeast late last week. The storm dropped heavy, wet snow in areas west of Interstate 95, leaving feet of snow in some areas. One 88-year-old woman died Wednesday when a tree fell and struck her in Suffern, in southern New York, police said.This winter's snowfall totals so far sit around the annual average at this point for the major Northeast hubs of Boston, New York and Philadelphia, according to the National Weather Service. 1937

A standoff between police and an armed suspect that resulted in one officer's death and the wounding of another remains underway Saturday afternoon in Pomona, California, near Los Angeles, more than 15 hours after it began.The suspect is barricaded inside an apartment home after fatally shooting an officer and wounding a second one, according to the Los Angeles County Sheriff's Department."It is with a heavy heart that I must report that one officer did not survive," Pomona police Chief Michael Olivieri tweeted early Saturday morning. "The second officer is in stable condition."  599

A Russian journalist and Kremlin critic, reported to have been shot dead in Ukraine, has appeared alive at a news conference.Arkady Babchenko was earlier reported to have been killed in his apartment building in the Ukrainian capital Kiev,.Ukrainian state news agency Ukrinform had said that Babchenko, 41, was shot in the back and died in an ambulance, citing his friend and supervisor, Ayder Muzhdabaev, deputy general manager of Ukrainian TV channel ATR.Police in Kiev said Babchenko's wife found him outside their apartment.But Ukrinform later reported that Babchenko was alive.This is a developing story - more to comeThe-CNN-Wire 643

A mysterious cigar-shaped object spotted tumbling through our solar system last year may have been an alien spacecraft sent to investigate Earth, astronomers from Harvard University have suggested.The object, nicknamed 'Oumuamua, meaning "a messenger that reaches out from the distant past" in Hawaiian, was first discovered in October 2017 by the Pan-STARRS 1 telescope in Hawaii.Since its discovery, scientists have been at odds to explain its unusual features and precise origins, with researchers first calling it a comet and then an asteroid, before finally deeming it the first of its kind: a new class of "interstellar objects."Now, a new paper by researchers at the Harvard Smithsonian Center for Astrophysics raises the possibility that the elongated dark-red object, which is 10 times as long as it is wide and traveling at speeds of 196,000 mph, might have an "artificial origin.""'Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization," they wrote in the paper, which has been submitted to the Astrophysical Journal Letters.The theory is based on the object's "excess acceleration," or its unexpected boost in speed as it traveled through and ultimately out of our solar system in January 2018."Considering an artificial origin, one possibility is that 'Oumuamua is a light sail, floating in interstellar space as a debris from an advanced technological equipment," wrote the paper's authors, suggesting that the object could be propelled by solar radiation.The paper, written by Abraham Loeb, professor and chair of astronomy, and Shmuel Bialy, a postdoctoral scholar, at the Harvard Smithsonian Center for Astrophysics, points out that comparable light-sails already exist on earth."Light-sails with similar dimensions have been designed and constructed by our own civilization, including the IKAROS project and the Starshot Initiative. The light-sail technology might be abundantly used for transportation of cargos between planets or between stars."In the paper, the pair theorize that the object's high speed and its unusual trajectory could be the result of it no longer being operational."This would account for the various anomalies of 'Oumuamua, such as the unusual geometry inferred from its light-curve, its low thermal emission, suggesting high reflectivity, and its deviation from a Keplerian orbit without any sign of a cometary tail or spin-up torques."'Oumuamua is the first object ever seen in our solar system that is known to have originated elsewhere.At first, astronomers thought the rapidly moving faint light was a regular comet or an asteroid that had originated in our solar system.Comets, in particular, are known to speed-up due to a process known as "outgassing," in which the sun heats up the surface of the icy comet, releasing melted gas. But 'Oumuamua didn't have a "coma," the atmosphere and dust that surrounds comets as they melt.Multiple telescopes focused on the object for three nights to determine what it was before it moved out of sight. 3063

A new internal document shows the Transportation Security Administration's proposal to eliminate screening at more than 150 small to medium sized airports is just one of several cost-saving measures the agency is discussing.The document, which an agency source says TSA Administrator David Pekoske was briefed on last month, shows how the TSA could save more than 0 million in 2020.Among the proposed cuts listed in the document are a reduction in full-time air marshals, a reduction in the workforce at TSA headquarters, fewer reimbursements to airports for janitorial services at TSA checkpoints, cuts for benefits for new part-time employees and a 50% cut in reimbursements to state and local law enforcement agencies for use of their K-9 units.The TSA did not respond to multiple requests for comment.Spending cuts would have to be approved by Congress, which sets the TSA's budget. 902
