As the most common type of weather occurrence in many partsof the globe, Severe Thunderstorm Watches especially during warmer months, when atmospheric conditions are just right for their formation severe thunderstorms involve thunderstorms that produce winds in excess of 33m/s during heavy downpours, frequent lightning or a tornado and it’s by no means coincidental that few release tools from meteorologists describe as readily as a severe thunderstorm watch the potential risk of severe weather.
What Is a Severe Thunderstorm Watch?
This, therefore means that the weather forecasting agencies in their concern hold that there is a good potential for the development of thunderstorms that are severe in nature in such an area. A severe thunderstorm watch, therefore serves more as a public alert concerning the possibility that severe weather may affect the area.
Issuance Guidelines
Tornadoes: Even though this criteria rarely lead to one happening, it may indeed cause a tornado to occur.
Outside the US, Canada, and indeed most of the rest of the world, a tornado watch is issued when thunderstorms are possible that could produce winds at least 90 km/h or more, hail larger than 2 cm in diameter, or more than 50 mm of rain in an hour or less12.
The Difference Between Watches and Warnings
This does not mean that watch and warning are the same.
- The word is in the timing: whereas a clock puts it across that it is already late, it is still early to sprint to a shelter, a warning points that it is already happening or is going to happen soon
- Hurricane-force winds: These will uproot trees and buildings torn from their foundations can cause flying debris that will be lifted
- Hailstones of large sizes: In the case of intense hail, it can cause widespread destruction to automobiles, roofs, and crops.
- Flash Flooding: The larger amount of rainfall than a drainage system can handle causes sudden flooding in such lowland areas.
- Tornadoes: Occasionally, with highly intense thunderstorms that eventually evolve into tornadoes, extreme life and property risk exposures do occur .
The extent of the effects of these storms can vary quite considerably with local topography and infrastructure. For example, in the urban areas, impervious surfaces enhance flooding whereas in the rural areas, water penetrates better 13.
Observation of Severe Thunderstorms
Meteorologists make extensive use of various tools involved in storm tracking and forecasting. Among some of the most common ones used are:
- Radar Technology: Doppler provides for immediate observation of the development of the storm, monitoring of rain intensity and motion of the storm.
- Satellite Imagery: Weather satellites can view much more of the atmosphere which may bring thunderstorms.
- Weather Models: Numerical weather prediction models that help in giving forecasts about when and where storms are likely to happen based on the current atmospheric data .
Precaution during Severe Thunderstorm Watches
Plan a storm that takes you indoors by utilizing safe rooms such as a basement or interior rooms.
- Outdoor Furniture and Decoration: Bring them indoors or tie up outdoor furniture, decorations etc., anything else that becomes a strong projectile when the wind blows.
- Emergency Kit: You should be prepared with sufficient supplies of commodity for yourself and your loved ones, including water, food, flashlights, batteries, medication, and first aid kits.
Conclusion
A timely yet critical tool in forecasting the weather-the severe thunderstorm watch-permitted the community to prepare for the threat of some potentially dangerous storms. Knowing and preparing can be part of the risk mitigation related to severe thunderstorms.
In such a state of continuous influence of climate changes on the world’s weather conditions, then the occurrence of intensive and severe weather may rise.
