Difference between Tornado Warning and Tornado Watch – Understanding the Two Alerts
Living in an area that is prone to tornadoes can be quite scary, especially during the stormy season. There are two alerts that are commonly issued by the National Weather Service (NWS) to warn residents about possible tornadoes. It is essential to understand the difference between a tornado warning and a tornado watch to stay safe during a storm.
What is a Tornado Watch?
A tornado watch alerts people in a particular area that the conditions are favorable for the formation of a tornado. It means that an area is experiencing weather conditions that are suitable for a tornado to form. In most cases, a tornado watch is issued for a large area and lasts for several hours. It provides people with a heads-up about the possibility of a tornado and urges them to stay updated with the current weather conditions.
During a tornado watch, people should keep an eye on the weather forecasts and listen to their local media outlets for updates. They should also develop a safety plan and prepare an emergency kit that includes important documents and supplies such as food, water, and batteries. People should also consider limiting their outdoor activities and avoid going out if possible.
What is a Tornado Warning?
A tornado warning is a more severe alert issued to a specific area by the NWS. It means that either a tornado has been sighted or there is strong evidence of its formation. When a tornado warning is issued, people in the affected area should take immediate action to protect themselves and their families.
During a tornado warning, people should head to the basement or an interior room on the lowest level of their homes. They should stay away from windows and external walls and cover themselves with blankets or mattresses to protect themselves from flying debris. People should also turn off their gas and electricity and avoid using elevators. If people are outside, they should try to find shelter indoors.
In summary, a tornado watch warns people that the conditions are conducive to a tornado formation, while a tornado warning indicates that a tornado has been sighted or is highly likely to form. Understanding the difference between the two alerts can help people stay safe during a storm and prevent potential damages to their property.
