Instead of gathering a widespread assortment of the week's best articles, videos, and photos, I've included the most thought-provoking and eye-opening articles on Sandy and her aftermath. Some are snapshots of people and places, others take a look at the science of the storm, and some take a look at the political effects of a storm that has caused tens of billions of dollars in damage and more than 150 deaths internationally. The articles begin with a blog posted on October 24.

Please share the best articles you've read about Sandy in the comments section.

The deterministic runs from the various global models continue to diverge, with some still showing a track out to sea (GFS and CMC) and some showing a more northerly track into the northeast U.S. coast (ECMWF and NOGAPS). It’s unclear yet which will verify, if any, but the ensembles have been trending westward, with more members now showing a very powerful cyclone (probably not completely tropical) slamming into the mid-Atlantic and Northeast states.

The ominous forecast by last night’s ECMWF deterministic run places an incredibly strong cyclone off the New Jersey coast on Monday evening ... with tropical storm to hurricane force winds covering every state between Virginia and Maine (note that the wind speeds on this map are at 5,000’ altitude, not the surface). A scenario such as this would be devastating: a huge area with destructive winds, extensive inland flooding, possibly heavy snow on the west side, and severe coastal flooding and erosion.

"Perfect Storm" Set to Occur on 21st Anniversary of Historic Event

While there is still inherent uncertainty in the forecast, especially considering we are at least five days away from the phase, the majority of the numerical guidance has now come into agreement that a phasing event will occur precisely on the 21st anniversary of the Perfect Storm somewhere between the mid-Atlantic states through Maine or potentially the Nova Scotia region. Most of the models now indicate even stronger jet dynamics will occur next week than occurred during for the Perfect Storm, and that today’s storm could potentially deepen to well below 960mb or even below 950mb. The fact that the Gulf Stream is anomalously warm for this time of year means that Sandy will weaken less as a tropical system than it otherwise would have prior to the phase. Also, a very strong blocking scenario (very negative NAO) has developed over the north Atlantic means that the cyclone will be very slow moving, and is likely to retrograde westward into the northeastern U.S. rather than continue out to sea like most recurving extratropical cyclones do. While it is too early to pin-down exact impacts from the system at this time, it is likely that portions of the coastal Northeast will experience a damaging storm surge, significant beach erosion, and a prolonged severe wind and heavy rain event. Meanwhile, interior regions of western Pennsylvania into Ohio may simultaneously be experiencing heavy snowfall. Stay tuned!
