A storm system that brought light icing to the Northeast caused hundreds of accidents on Jan. 18, 2015. Heavy rain and some snow also accompanied the storm.

The storm did not meet for warning-level winter weather required to be a named winter storm. However, at one point freezing rain advisories – less serious than an ice storm warning, which would have counted toward those thresholds – included some 32 million people on the morning of Jan. 18, 2015.

Though the icing was light in most areas, the Northeast region saw significant impacts, including near the heavily-populated I-95 corridor. Reports of accidents, slick roads and closures due to the ice were widespread from southeast Pennsylvania to New England.This is another example that shows it only takes a small amount of ice accumulation to cause big problems on roadways.

Among the impacts were a deadly multi-vehicle pileup on I-76 northwest of Philadelphia and more than 400 accidents in New Jersey from midnight Jan. 18 to around lunchtime that same day. You can find photos, video and more on the travel problems the storm caused

There were numerous reports of freezing rain and ice accumulation on Jan. 18, 2015 across parts of eastern Pennsylvania, New Jersey, southeastern New York (particularly around New York City and the Hudson Valley), Connecticut, and central and western Massachusetts. Amounts reported by trained spotters were generally 0.10 inch or less.

The icy mess later changed over to heavy rain, prompting a rare severe thunderstorm warning on Long Island on the evening of Jan. 18 and bringing reports of flooding around the New York City area.

Central Park in New York City reported 2.10 inches of rain, making it the 10th-wettest January calendar day since records began in 1874. It was also the wettest January calendar day since Jan. 3, 1999, when 2.42 inches fell.
