Public Information Statement
National Weather Service New York NY
527 AM EDT Fri Nov 4 2016


Please join the National Weather Service and the New York State
Office of Emergency Management in promoting winter weather
education, including safety.

The topic for today is watches, warnings, and advisories.

The NWS issues two types of winter weather watches,
blizzard and winter storm.

There are also four types of winter weather warnings,
blizzard, ice storm, winter storm, and wind chill.

There are also three types of winter weather advisories,
winter weather, freezing rain, and wind chill.

Watches and warnings are issued for potentially life threatening
hazardous weather. Watches are usually issued 24 to 36 hours
before an event is expected. Warnings are usually issued up to 24
hours before an event. Advisories are issued for less serious
events up to 24 hours before they occur.

A blizzard watch and warning will be issued for sustained winds
or frequent wind gusts to 35 mph or greater, and considerable
falling and/or blowing snow, frequently reducing visibilities
below 1/4 mile, for a period of 3 hours or longer.

Winter storm watches and warnings are issued for,

heavy snow, when an average of at least 6 inches in 12 hours or 8
Inches in 24 hours is forecast.

Significant freezing rain, when at least one half inch of ice
is forecast.

A combination of snow, sleet, and freezing rain expected to cause
impacts similar to those of either heavy snow or significant
freezing rain.

Wind chill watches and warnings are issued when air temperatures
and sustained wind speeds are forecast to produce wind chills of
at least minus 25 degrees.

Flood watches and warnings are issued for flooding of rivers,
small streams, and streets, and poor drainage areas. Heavy rain
lasting at least 6 hours is usually a major cause of flooding.

Coastal flood watches and warnings are issued for at least
widespread moderate tidal flooding of shorelines.

High wind watches and warnings are issued for sustained winds
averaging at least 40 mph for at least 1 hour, or for wind gusts
reaching at least 58 MPH for any duration.

Advisories will be issued for lower amounts or values and cover
winter weather, blowing snow, freezing rain  or freezing drizzle,
wind and wind chill, and dense fog.
