Mayor Bill de Blasio says all city agencies are all coordinating their efforts ahead of this weekend's snowstorm.

Snow is expected to start Saturday in the early morning hours and will continue on and off through most of the day.

About four to eight inches of snow is expected to fall in and around the city, but higher totals are possible if the storm stalls or rapidly intensifies.

The National Weather Service notes that winds will be very strong on Saturday, setting up the possibility for a period of blizzard-like conditions.

Blowing snow means visibility will be reduced even if there is not a huge amount of snow.

As a result, the mayor has issued a hazardous travel advisory for both Saturday and Sunday.

Starting Friday morning, the city Sanitation Department says workers will begin working 12 hour shifts with thousands of employees spreading salt throughout the five boroughs.

The mayor advises New Yorkers to call 311 if they have any issues, especially concerning the lack of heat or hot water.  

As of now the mayor expects normal school schedules for both Friday and Monday.

The Big Apple has only seen four-tenths of an inch of accumulation this year. 

With Saturday's storms the plows and salt spreaders will be busy.

City agencies say they're grateful that the storm isn't hitting on a busy weekday commute.

"The good news is I guess for some people, the snow will be on the weekend. So it doesn't affect schools too much, it doesn't affect commuting too much. But sanitation, the DOT, they have their plans that they roll in depending on how much snow we're gonna get," OEM Commissioner Joseph Esposito told reporters Wednesday.
