While many areas have experienced unseasonably warm weather, as a certain television program might say: "Winter is coming." The ice and snow can be a welcome change for some, but it also makes sense to familiarize yourself with some of the terminology used by the National Weather Service so that, if they issue a winter advisory in your area, you will be able to accurately assess the dangers and plan accordingly.

Here is a guide to the four major winter advisories, as issued by the National Weather Service, and what you should do to make sure you are ready.

Winter Storm Outlook

This warning means that a storm is on its way and is scheduled to arrived in roughly three to five days. Use this time to make sure you are stocked up on your emergency supplies and evaluate your emergency plan.

Winter Storm Watch

This is a more immediate warning, usually referring to heavy snow, freezing rain and other hazardous conditions arriving within the next 12 to 48 hours. Watch out for closings of local facilities like schools and roads and keep an eye on the forecast for additional information.

Winter Storm Warning

This means that the weather coming soon (within the next 12 to 48 hours) is dangerous, potentially even life-threatening. Avoid leaving the house until advised and stay off the roads. Bring all animals indoors and make sure your phone is charged so you can receive any Wireless Emergency Alerts for your area.

Winter Storm Advisory

A less severe version of the winter weather warning, though snow and ice are still likely to cause travel delays and other dangerous conditions. Use caution, stock up on food and gas, and otherwise pay attention to further advisories.
