Advisory vs Warning – Difference and Comparison

What is Advisory?

Advisory may be defined as the conditions that are likely to occur. To be precise, advisories are a sort of announcement that is made wherein the weather phenomenon doesn’t necessarily affect the individual’s properties or put their lives at risk. And propose correct precautions, which if followed diligently will help them in coping with the situations.

Advisories are used to denote less severe weather conditions like frost or winds. Also, advisories are issued at any time before the event but not more than 36 hours in advance.

As far as the weather experts are concerned, for issuing advisories, they come up with alternative routes and advise the people to restrict their movement for a certain period.

What is a Warning? 

Warning may be defined as the conditions that are occurring and imminent. In other words, warnings are issued by the weather experts to the public at times when some upcoming events are likely to cause damage to the properties or cause death to some or a significant number of people in a region. 

Warnings are likely to span over much smaller areas and last for a definite period. For instance, high wind warnings are issued when winds are sustained at 40 miles an hour for any duration. Warnings may be issued at any time but not more than 24 hours in advance.

Further, the situations like floods, landslides, and other man-made structures at times need careful adherence to warnings led by the municipal town committees for that specific period.
