There does not appear to be such an incident based on a look at available data. Such a situation is unlikely to arise, since the Storm Prediction Center is in charge of issuing both severe weather outlooks and tornado watches. If it saw fit to issue a PDS tornado watch, it would likely issue a moderate or high risk outlook as well.
Generally speaking, yes. A tornado watch means that tornadoes are possible. A severe thunderstorm watch means that severe thunderstorms are possible. Although severe thunderstorms can cause damage they are not nearly as destructive as tornadoes can be.
Yes. The Granbury, Texas EF4 tornado of May 20, 2013 ocurred in an area that was under both a tornado watch and a severe thunderstorm watch.
The severe weather watch is when a group of meterologist decide that conditions are appropriate for an abnormally severe storm to occur. They will then alarm the public that it is likely for one of these storms to occur. Therefore, it is a good idea to be on the look out to prevent injury.
A severe thunderstorm watch means that general conditions in a region favor the formation of severe thunderstorms. It does not indicate any immediate threat. When a storm becomes severe or threatens to become so, a severe thunderstorm warning is issued. Severe thunderstorms carry the risk for wind gusts to 58 mph or greater, hail 1" or larger in diameter, and tornadoes. Note, though, that if conditions are favorable for thunderstorms to produce tornadoes, a tornado watch is issued instead.
It is too early to tell. Currently the area under the high-risk outlook is covered by two tornado watches, which discuss the non-tornadic threats that would be covered by a severe thunderstorm watch.
Generally speaking, yes. A tornado watch means that tornadoes are possible. A severe thunderstorm watch means that severe thunderstorms are possible. Although severe thunderstorms can cause damage they are not nearly as destructive as tornadoes can be.
Yes. The Granbury, Texas EF4 tornado of May 20, 2013 ocurred in an area that was under both a tornado watch and a severe thunderstorm watch.
Yes essentially. A severe thunderstorm watch means severe thunderstorms are possible. A tornado watch means tornadoes are possible. Severe thunderstorms can cause damage, but not nearly as much as tornadoes potentially can.
No. A severe thunderstorm watch and a tornado watch would of course be stronger than a flash flood watch.
The severe weather watch is when a group of meterologist decide that conditions are appropriate for an abnormally severe storm to occur. They will then alarm the public that it is likely for one of these storms to occur. Therefore, it is a good idea to be on the look out to prevent injury.
If a moderate risk of severe weather is issued there will almost certainly be severe thunderstorm watches or tornado watches issued.
A tornado/thunderstorm watch means that weather conditions are good for tornado/thunderstorm. A tornado/thunderstorm warning, however, means that conditions are extreme and a thunderstorm or tornado is likely. Conditions for either storm are very good at this stage.
A severe weather watch informs you when the conditions are right for severe weather to happen, while a warning means it is happening or is imminent, and is warning you to take immediate action.
No. That would be a severe thunderstorm watch. A severe thunderstorm warning means that a severe thunderstorm ha already formed.
A severe thunderstorm watch means that general conditions in a region favor the formation of severe thunderstorms. It does not indicate any immediate threat. When a storm becomes severe or threatens to become so, a severe thunderstorm warning is issued. Severe thunderstorms carry the risk for wind gusts to 58 mph or greater, hail 1" or larger in diameter, and tornadoes. Note, though, that if conditions are favorable for thunderstorms to produce tornadoes, a tornado watch is issued instead.
As of 12:30 EDT on March 18, 2013 Spring City, Tennessee is not under a tornado watch. It is, however under a severe thunderstorm watch. A tornado warning has been issued near Lewisburg, though that is some distance from Spring City.
There is a good chance that one or both could be issued, given the outlook.
