States along the East Coast are grappling with high winds, rain, snow and flooding Friday as Winter Storm Riley intensifies — but the effects of the massive Nor'easter aren't limited to the land and sea.

The storm is large enough to be seen from space, prompting New York-based meteorologist John Homenuk to tweet a wild aerial view of the East Coast.

Winter Storm Riley is the East Coast's second bomb cyclone of the year. The weather event is caused by a phenomenon called bombogenesis, which occurs when a storm drops 24 millibars of atmospheric pressure over the course of a 24-hour period, resulting in extreme weather conditions. The rapid uptick in precipitation often leads to flooding along the coast.

That's been the case for Winter Storm Riley, which has already dropped more than a foot of snow in some parts of New York and Pennsylvania. New York City got an unexpected hit of wet, heavy snow, while Boston may get up to a foot of fresh powder in the next 24 hours, according to ABC News. Boston is also experiencing extreme flooding, with harbor levels at their third-highest since the National Weather Service began monitoring that statistic in 1928.

The Nor'easter has also made weekend travel a nightmare, leading to nearly 4,000 flight delays and cancelations as of Friday morning. Many airlines, including Jet Blue, Delta and more, preemptively offered flight waivers and free cancelations for travelers who were affected by Winter Storm Riley.
