Severe Weather- What does it all Mean?

This week's snow storm has created a lot of buzz in Central Ohio and, unfortunately, there is more to come. Some people love the snowy weather, some hate it (I put myself in this category). Either way, we all need to remember to be careful, cautious, and prepared for severe winter weather. All of Central Ohio has been under a winter weather advisory or watch, and some counties are under various levels of snow emergency. With all of the weather terminology used, it is often confusing and hard to have more than just a general grasp of what it all means. Let me try to break it down with some key terms that are often used in weather alerts.

According to the National Weather Service, there are three major types of severe weather alerts: watch, advisory, and warning. A watch is issued when the risk of a hazardous weather 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. This is the least severe weather alert. An advisory is issued for events that may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may threaten life or property. This alert is more severe than a watch, but less severe than a warning. Finally, a warning is issued when a hazardous weather 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. This is the most severe weather alert.

When a winter weather warning is issued, your county may be under a level of emergency. Level 1 emergency means that roads are hazardous and people should drive with caution.
Level 2 emergency means that driving is discouraged and you should call before heading to work. Finally, a Level 3 emergency means that only emergency vehicles should be on the roads and people could be arrested if they decide to drive on the local roads.

Hopefully this clears up some confusion about weather alert terminology. Whether a watch, advisory, warning, or leveled emergency- make sure that you are using the appropriate level of caution. Be safe out there!
