Hazard: Severe Winter Storm (See Mitigation Page for description on all hazards.)
As of November 21, 2013:
NOAA indicates that no strong climate pattern will emerge for the mid-Atlantic region this upcoming winter season. Below average percipitation will continue with drought conditions U.S. Southwest and Southereast.
Neither El Nino nor La Nina are expected to influence the climate this winter, as has been determined by average sea surface temperatures since spring 2012.
This proves it difficult to accurately predict local weather outcomes, as explained by NOAA's Mike Halpert. "Without this strong seasonal influence, winter weather is often affected by short-term climate patterns, such as the Arctic Oscillation, that are not predictiable beyond a week or two. So it's important to pay attention to your local daily weather forecast throughout the winter."

The Temperature Outlook favors:
The rest of the country falls into the "equal chance" catagory, meaning that there is not a strong or reliable enough climate signal in these areas to favor one category over the others, so they have an equal chance for above-, near-, or below-normal temperatures and/or precipitation.

When severe weather is forecasted, it is important for residents and business owners to monitor the situation and act proactively to protect themselves, their family and their property. Local officialls have a variety of ways to get information to the public. Emergency Information Sources.

What Qualifies as a Severe Winter Storm?
A severe winter storm event includes a storm with heavy snow, ice, or freezing rain - all of which can cause significant problems for residents. The County's greatest winter stroms are "Nor'easters."
What is a Nor'easter?
A strong low pressure system that affects the Mid Atlantic and New England States. It can form over land or over the coastal waters. These winter weather events are notorious for producing heavy snow, rain, and tremendous waves that crash onto Atlantic beaches, often causing beach erosion and structural damage. Wind gusts associated with these storms can exceed hurricane force in intensity. A nor'easter gets its name from the continuously strong northeasterly winds blowing in from the ocean ahead of the storm and over the coastal areas.
What is the difference between and Advisory, Watch and Warning?
An Advisory Highlights special weather conditions that are less serious than a warning. They are for events that may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may threaten life and/or property.
A Watch is used when the risk of a hazardous weather or hydrologic event has increased significantly, but its occurrence, location, and/or timing is still uncertain. It is intended to provide enough lead time so that those who need to set their plans in motion can do so.
A Warning is issued when a hazardous weather or hydrologic event is occurring, is imminent, or has a very high probability of occurring. A warning is used for conditions posing a threat to life or property.
Common Winter Storm Terminology:
Snow Squall - A snow squall is an intense, but limited duration, period of moderate to heavy snowfall, accompanied by strong, gusty surface winds and possibly lightning (generally moderate to heavy snow showers). Snow accumulation may be significant.
Winter Storm Watch - This product is issued by the National Weather Service when there is a potential for heavy snow or significant ice accumulations, usually at least 24 to 36 hours in advance. The criteria for this watch can vary from place to place.
Winter Storm Warning - This product is issued by the National Weather Service when a winter storm is producing or is forecast to produce heavy snow or significant ice accumulations. The criteria for this warning can vary from place to place.
Ice Storm Warning - This product is issued by the National Weather Service when freezing rain produces a significant and possibly damaging accumulation of ice. The criteria for this warning varies from state to state, but typically will be issued any time more than 1/4" of ice is expected to accumulate in an area.
Blizzard Warning - Issued for winter storms with sustained or frequent winds of 35 mph or higher with considerable falling and/or blowing snow that frequently reduces visibility to 1/4 of a mile or less. These conditions are expected to prevail for a minimum of 3 hours.
Winter Weather Advisory - This product is issued by the National Weather Service when a low pressure system produces a combination of winter weather (snow, freezing rain, sleet, etc.) that present a hazard, but does not meet warning criteria.
Freezing Rain Advisory - Issued when freezing rain or freezing drizzle is forecast but a significant accumulation is not expected. However, even small amounts of freezing rain or freezing drizzle may cause significant travel problems.
Wind Chill Advisory - The National Weather Service issues this product when the wind chill could be life threatening if action is not taken. The criteria for this warning varies from state to state.
