No, the presence of hail does not necessarily indicate that a tornado is imminent. While hail can be associated with severe thunderstorms that may produce tornadoes, it is not a definitive indicator of an imminent tornado.
Hail most often occurs ahead of the tornado but it also frequently found in the hook of the storm, which wraps around behind and to the left of the tornado (with respect to its movement) in the northern hemisphere and to the right of it in the southern hemisphere.
No. Hail stones are caused by rising air in thunderstorms that blows rain upward to the height of the atmosphere in which temperatures are freezing. Many tornado producing storms have strong updrafts and also produce hail---but you can have hail without a tornado and likewise you can have a tornado without any hail.
Tornadoes typically do not produce their own precipitation. Instead, they form from existing thunderstorms that may already be producing rain or hail. When a tornado does occur in the presence of precipitation, it can be difficult to see due to heavy rain and may be obscured by a curtain of water.
Yes, tornadoes and hail can occur together during severe thunderstorms. The strong updrafts and turbulent conditions within a thunderstorm can create hail, while the rotating updraft required for a tornado can also contribute to hail formation.
Yes, a thunderstorm that produces hail can be a good candidate to spawn a tornado. The strong updrafts that form hail in the storm can also create the necessary conditions for tornado development, such as a rotating updraft known as a mesocyclone. However, not all hail-producing storms will develop into tornadoes.
Tornadoes are often but not always accompanied by hail. However, the hail is not a result of the tornado itself but the storm that produces the tornado.
Hail most often occurs ahead of the tornado but it also frequently found in the hook of the storm, which wraps around behind and to the left of the tornado (with respect to its movement) in the northern hemisphere and to the right of it in the southern hemisphere.
It can. Hail often does come before a tornado, but most storms that produce hail do not produce tornadoes.
No, if there is a tornado or hail near a window is one of the least safe places to be.
Often, but not always.
There is no particular sky color that indicates a tornado is coming. It is often reported that the clouds look green before and during tornado. But this does not necessarily indicate a tornado, nor is it necessary for a tornado to form. The clouds in a tornadic storm may also appear gray or black.
Yes. The storm that produced the Joplin tornado also produced hail up to 1 inch in diameter in the Joplin area.
Yes. Tornadoes a very often accompanied by large hail.
No. Hail stones are caused by rising air in thunderstorms that blows rain upward to the height of the atmosphere in which temperatures are freezing. Many tornado producing storms have strong updrafts and also produce hail---but you can have hail without a tornado and likewise you can have a tornado without any hail.
A Tornado is usually accompanied by severe thunder storms and possibly hail
Direct warning signs of a tornado include rotation in the clouds and a persistent lowering of the cloud base. Many people associate hail or green skies with tornadoes. These signs do indicate a severe storm, but not necessarily tornadoes.
