Storm Watch

First snowstorm of the season arrives tonight. Here's the latest on timing and impacts.

Mayor Bill de Blasio is headed out of the country. 
The city's first family is leaving Friday for a 10-day trip to Italy, which will be the longest vacation by a mayor in recent memory. 
Former Mayor Michael Bloomberg never went away for a full week during his 12 years in office and former Mayor Rudy Giuliani only took off a handful of days. 
De Blasio says he will come back if there's a crisis.
