For each of the events described in the article is reported:
- A bried description of the event and its impact in air traffic.
- The delay propagation network with main propagators, absorbers and intermediary airports.
- Selected Shankey plots diagrams with delay flows.
- The airports with most cancelled flights.
- When it exists, the cancellation propagation network with main propagators, absorbers and intermediary airports.
For the baseline case we are presenting information related with delays, as the number of cancelled flights is negligible.
1 The January 2017 North America Winter storm (TE1)
The January 4–8, 2017 North American winter storm was a major snow and ice storm that affected the Lower 48 of the United States with winter weather. Moving ashore on the West Coast on January 3, the system produced heavy snowfall in the Sierra Mountains, with nearly 4 feet of snowfall falling in the highest elevations. After impacting the Northwest and Southwest, the winter storm went on to strike the Southeast on January 5–6 with snow and ice, with snowfall accumulations up to 4 inches (10 cm). Afterwards, it began to morph into a nor’easter as it moved off the Southeast coast late on January 6, while producing blizzard conditions in the Carolinas. It then began to affect the Northeastern United States as it tracked northwards early on January 7. It produced a swath of moderate snowfall accumulations up the East Coast, with easternmost areas such as parts of Massachusetts receiving up to 1.5 feet (18 in) of snow.

2 The February 9–11, 2017 North American blizzard (TE2)
The February 9–11, 2017 North American blizzard was a fast-moving but powerful blizzard that affected the Northeastern United States with winter weather in the time span of February 8–9. Forming as an Alberta clipper in the northern United States, the system initially produced light snowfall from the Midwest to the Ohio Valley as it tracked southeastwards. It eventually reached the East Coast of the United States and began to rapidly grow into a powerful nor’easter. Up to 18 inches (46 cm) of snow as well as blizzard conditions were recorded in some of the hardest hit areas before the system moved away from the coastline early on February 10.

3 The March 2017 North American Blizzard (TE3)
The March 2017 North American blizzard was a major late-season blizzard that affected the Northeastern United States, New England and Canada, dumping up to 3 feet (36 in; 91 cm) of snow in the hardest hit areas, mainly New York, Vermont, New Hampshire and Southern Quebec. Forming out of an extratropical cyclone near the Northwest, the storm system dived into the northern portions of the United States, dropping light to moderate snow across the Great Lakes, Upper Midwest on March 11–12 before reaching the Ohio Valley the next day. It later coalesced into a powerful nor’easter off the East Coast, producing a swath of heavy snowfall across a large portion of the Northeast. The storm was given various unofficial names, such as Winter Storm Stella, Blizzard Eugene, and Blizzard of 2017.
Ahead of the storm, residents prepared in advance for the major nor’easter, with blizzard warnings issued for several states, including New York, Pennsylvania, New Jersey, Connecticut, Rhode Island, and Massachusetts. Several officials had crews with salt trucks ready to deploy to clear roads. The system also disrupted travel across the country, with numerous flight cancellations at most of the major airports in the Northeast. It dropped a swath of moderate snow accumulation as it moved across the northern tier of the country, with as much as 13 inches (33 cm) reported. The storm was also responsible for ending a record streak without snowfall in Chicago, Illinois, where no snow had occurred since December 25, 2016.

https://edition.cnn.com/2017/04/07/business/storms-delta-cancellations/index.html
Delta Air Lines, still working to get back to normal days after thunderstorms blew through the eastern US on Wednesday, had to scrub about 275 more flights on Saturday.
The No. 2 US airline, which already canceled around 3,000 flights in the wake of the powerful mid-week storms, said in a statement on Saturday that it’s possible even more flights will be called off, stranding and frustrating passengers during one of the busiest travel weeks of the year.

5 Hurricane Irma September 2017 (TE5)
Article of 11 September 2017 (source: https://thepointsguy.com/2017/09/flight-cancellation-southeast-irma/=
After making landfall in the Florida Keys on Sunday, Hurricane Irma made a beeline up the Florida peninsula, hitting the city of Naples on the mainland and moving up north at a steady pace. Next in its crosshairs: Georgia and Alabama.
The storm is just north of Tampa at midday Monday, with its center of circulation forecast to head northwest toward Tallahassee, Florida, and then over Birmingham, Alabama, on Tuesday morning. However, the strongest impacts from the storm will continue to be to the east of the circulation. And there’s a major airport there: Atlanta’s Hartsfield-Jackson Airport (ATL).
Meanwhile, it’s going to take a day or two for operations to get restarted in Florida airports, including American Airlines’ hub Miami International (MIA). That means both Delta and American Airlines are facing a rough couple of days.
More info about hurricane Irma, and its impact in US:
Wikipedia article (https://en.wikipedia.org/wiki/Hurricane_Irma):
Hurricane Irma affected multiple states in the South, especially Florida. Except for the Florida Keys, the total damage Irma caused was not as great as government officials and forecasters had warned. Irma weakened after making landfall in Cuba, but strengthened back into a Category 4 prior to hitting the Keys. The Florida Keys suffered the worst of the damage in the United States.
