Already up to 12 inches of snow fell in western Pennsylvania, where travel was impossible at times on I-90. We are not expecting severe weather, but there could be a few stronger storms tomorrow afternoon.
The nor'easter has also prompted the cancellation of more than 3,300 flights, snarled ground traffic and knocked out power to 900,000 customers with more than 400,000 of them in MA, reports CNN. The duration of the wind will be most of the day on Friday and weakening into Saturday morning.
More than half the flights scheduled to arrive and depart from New York's LaGuardia Airport were cancelled, with sweeping disruptions at Boston Logan International and New York's two other area airports, Newark and John F. Kennedy International.
Urban flooding is possible, especially in Southeast New England.
State politicians are warning constituents to take the storm seriously, with Massachusetts Gov Charlie Baker announcing that he was mobilising 200 National Guard members to help with the storm's fallout, according to the Associated Press.
And the snow that falls will be the wet gloppy, heavy variety. Trees, limbs and power lines could come down as well from the strong winds. So scary, right? Riley is expected to hit the Atlantic coast, and people from Chicago all the way to Boston may experience really harsh conditions.
As a bomb cyclone develops, the risk for coastal flooding is high, in this case in areas surrounding Boston and southern NY. Snowfall accumulations could be 3-8 inches with locally higher amounts of 10 inches possible.
"Flooding from rainfall is also a concern; 2-4" inches of rain are possible and there is flood warning for the Pawtuxet River in Cranston; minor to moderate flooding is possible late Friday into Saturday.
Winter will not go quietly - at least not yet - as a powerful n'oreaster is set to plow its way through the region from late tonight through Friday night. Over 2 inches of rain has fallen from OR to Northern California, with reports of flooding in the San Francisco Bay area.
