The New York State Division of Homeland Security and Emergency Services on Friday released a 49-page report breaking down the state's response to December's blizzard in Buffalo where 47 people died.

Several issues were alleged in the report, including the state's emergency alert system not being used due to a low number of subscribers.

The report also notes local and state entities were allegedly unfamiliar with coordination efforts and the state's emergency operations center was not staffed properly.

The state's comprehensive emergency management plan centered in part around clearing roadways. There was also reportedly no specific chapter in that plan specifically covering blizzards.

Another issue highlighted is the state and Erie County allegedly using two different types of emergency management software that were not entirely compatible with one another, which is now being disputed.

The review board is making a dozen recommendations, including the state growing the subscriber base for the NY-Alert app, clearly communicating risks in advance and getting all government agencies on the same page.

A spokesperson for Buffalo Mayor Byron Brown released a statement, saying:

"The Mayor is aware the State's After Action Report for the response to the December Blizzard is completed.  City staff participated in the process as requested and we are currently reviewing the document. As previously announced, the City has established a Storm Response Task Force and has already purchased new equipment and adopted new storm-fighting procedures."

Erie County Executive Mark Poloncarz also released a statement, where he, in part, denied software compatibility issues:

More than 600 people were rescued during the blizzard and more than 104,000 residents lost power.
