What are three warning signs of a tornado?

Answer 1

Signs that a tornado may soon form include rotation in the clouds of a thunderstorm, a persistent lowering of the cloud base, and a clear slot opening up in the clouds in or near that rotation.

Answer 2

There are several signs of a tornado approaching. I will list them here in order of urgency.

Rotating Thunderhead: generally, a spinning thunderstorm means that it could sport a tornado. This isn't always a sign, though because it could be just a normal thunderstorm.

Mammatus Clouds: lumpy clouds on the bottom of a thunderhead often indicates lots of instability and rotation in the cloud which can cause tornadoes. Tornadoes often form anywhere from 1-90 minutes after the formation of these clouds.

Greenish Sky: in very big and dense thunderclouds, the light gets bent and causes the clouds to look green. A tornado could develop anywhere from 1-30 minutes after the change in sky color.

Continuous Lightning: in thunderheads with lots of wind and rotation, the lightning discharges are so frequent they seem constant. A tornado might develop about 30 minutes into the continuous lightning.

Large Hail: the more hail, the more updrafts, the more rotation, the more chance of a tornado. A tornado may strike anywhere from 1-20 minutes into the hailstorm.

Wall Cloud: when a whirlwind is getting ready to drop from a cloud and turn into a tornado, it forms a collar-like structure in the cloud called a wall cloud. A funnel may drop 1-15 minutes after the formation of the wall cloud

Freight Train Roar: High winds make this sound. A tornado may strike within 1-3 minutes

Flying Debris: A wall of a tornado could be very close. A tornado may hit in less than 20 seconds

Sudden Absolute Silence in the middle of a Severe Storm: a tornado could be about to touch down ON or right next to the area you are in.

Those are pretty much all the basic signs of a tornado, though if any of the last 3 signs are happening, there would already be a tornado warning on.

Answer 3

If we are assuming the you will get hit by the tornado, the following things often happen

1. a strong rotating thunderstorm will come to your town

2. mammatus clouds may form

3. the sky may turn greenish,

4. large hail may begin falling

5. a wall cloud will likely form near or approach your home

7. you may hear a jet-like roar

6. you will notice debris flying around

7. there will be a sudden absolute silence

8. a tornado will hit

Answer 4

Most tornadoes, especially significant ones, usually occur during severe thunderstorms called supercells. As the supercell approaches it may take on the appearance of stacked plates. As the potential tornado-producing region comes into view, you may see rotation in the cloud base, with part of the base lowered in what is called a wall cloud. If a funnel cloud appears in the wall cloud, a tornado may form in minutes or even seconds.

Answer 5

From the ground it can be difficult to distinguish a hurricane from a ordinary storm system at first. As a hurricane approaches the barometric pressure will start to drop, though this is true of any storm. The wind will begin to pick up and rain will start falling. Thunderstorms may occur in this pat of the storm. Conditions will progressively worse, alternating between periods of light and heavy rain as the spiral bands pass overhead. If a hurricane may impact your area pay attention to advisories from the National Weather Service and National Hurricane Center.

Signs of a tornado may be somewhat more distinct. Most tornadoes form in a type of rotating severe thunderstorm called a supercell. Warnings signs of a potential tornado include rotation in the clouds, a persistent lowering of the cloud base, and a hole opening up in the clouds in or near this rotation. A cone or funnel shaped cloud in this area means that a tornado is likely developing or may already be on the ground.

Other conditions often associated with tornadoes include a greenish sky and large hail. These are not necessarily indicators of a tornado, but they often accompany them and the hail can be dangerous in its own right.

Answer 6

Tornado warning signs can vary. Tornadoes are often accompanied by hail, though this is far from a certain warning. More definite signs of the precursor to a tornado. These include a lowering of the cloud base, rotation in the clouds, and a hole opening up in the clouds in or near this rotation. If you see a funnel cloud a tornado is developing to may already be on the ground. Sometimes the sky will turn a shade of green before a tornado, though this simply means that the storm is likely severe, not necessarily tornadic.

If you are looking at the radar and a hook shape forms on a storm cell, especially on the western or southern side. See the link below for a textbook example of this.

Answer 7

Three warnings signs of a tornado include a persistent lowering of the cloud base in one section of a thunderstorm, rotation in the clouds, and ears popping. This last sign means that a tornado is very close if not right on top of you.

1. funnel clouds
2. suspicious cloud rotation
3. often strong to severe thunderstorms that produce hail can sometimes produce tornadoes
4. supercell thunderstorms

• Strong, persistent rotation in the cloud base
• Whirling dust or debris on the ground under a cloud base-this may indicate a tornado funnel that is still inside the cloud
• Hail or heavy rain followed by either dead calm or a fast, intense wind shift. Many tornadoes are wrapped in heavy precipitation and can't be seen
• Loud, continuous roar or rumble, which doesn't fade in a few seconds like thunder. A tornado also may sound like a waterfall, trains, and jets
• Night- Small, bright, blue-green to white flashes at ground level near a thunderstorm, opposed to lightning flashes or strikes. These mean power lines are being snapped by very strong wind, which may be a tornado
• The sky may be a greenish black color.
• Clouds moving by very rapidly, which indicates strong winds
• Debris falling from the sky
• A funnel cloud that hasn't touched the ground yet is a huge sign of a tornado.

If weather forecasting is available it is advisable to watch the weather channel or listen to the radio if you notice any of the above signs outside.

Answer 8

1. funnel clouds
2. supercell thunderstorms
3. cloud rotation
4. sometimes severe thunderstorms that produce hail heavy rain and strong winds
