Law enforcement officials have gathered at New York City police headquarters to discuss plans ahead of a busy September that will include a visit from the pontiff and the president.

The NYPD’s John Miller told dozens of commanding officers, federal authorities and emergency responders Wednesday the month is “almost a perfect storm of security challenges.”

Those include the arrival of about 160 world leaders to the United Nations, Pope Francis’ visit to the U.S. and President Obama’s address at the U.N. General Assembly.

Police officials from Washington D.C. and Philadelphia also attended the so-called tabletop exercise.

Miller told those in attendance the point was to make multiple plans for potential problems, attacks and other emergency scenarios.
