Watches, Warnings and Advisories.  What's the difference?

Watch-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.

Warning- 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.

Advisory- 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.

What IS the difference between a Thunderstorm Watch and a Warning?

A severe thunderstorm Watch means that conditions are favorable for development of a severe  thunderstorm in or close to the watch area. Severe thunderstorms may produce large hail or damaging winds. When a watch is issued, you should review thunderstorm safety rules and be prepared to move to place of safety if threatening weather approaches. Keep an eye to the sky and an ear to the National Weather Service's weather radio or local radio and television stations for further updates and possible warnings.

A severe thunderstorm Warning, on the other hand, means that a severe thunderstorm is occurring or is imminent in the Warning area based on doppler radar information or observation by a trained weather spotter. You should move indoors to a place of safety. Schools should think about delaying departure of buses, and should take quick action to delay outdoor sports activities, etc.

Storm Surge explained.  "Storm Surge" is an abnormal rise of water generated by a storm, over and above the predicted astronomical tide produced by water being pushed toward the shore by the force of the winds moving around a storm. A "Storm Tide" is the combination of both storm surge and the astronomical tide. Storm Surge, Storm Tides or Coastal Flooding can be deadly!  Nine out of ten deaths from hurricanes can be attributed to these storm phenomena.

Cupcake"Aha moment!" To simplify a question most asked, we were sent a humorous analogy by a resident that illustrates the Watch vs. Warning concept
(weather can be fun!)
