Mayor De Blasio responded to heavy criticism over the city's preparation, or lack-there-of, for Thursday's snow storm.

De Blasio led a press conference after a wave of comments from New Yorkers upset over extended delays on roads and public transportation.

The mayor said while he was also frusturated with traffic, news of the storm bringing more than an inch or two of snow did not come until mid-afternoon. 

He believes that was too late. 

De Blasio says while the city is planning a full review of how it could have improved it's response, an apology is not necessary. 

"I'm upset that New Yorkers went through it. I don't think it's fair to say the city agencies could've stopped all of this. I'm not going to do that because I think that's just too convenient. If people want to blame city agencies on something that they literally could not have stopped, I'm not going to be party to that," de Blasio said. 

Sanitation commissioner Kathryn Garcia said that the department dispatched as many as 700 plows after learning that more than three inches of snow could fall.

The department usually sends out roughly 1,600 in anticipation of a larger blizzard.
