Does lightning travel from east to west?
The answer is BOTH: There are distinct types of lightning strikes to earth that can travel in either direction - cloud-to-ground lightning and ground-to-cloud lightning. For each of these types of lightning, current flow and leader development can also take place in both directions.
This is typically caused by wind blowing the lightning channel sideways during the exposure. The stronger the wind and closer the lightning strike, the more horizontal displacement will exist on the recorded image.
Lightning can also travel from one cloud to another, or cloud-to-cloud (CC). Spider lightning refers to long, horizontally traveling flashes often seen on the underside of stratiform clouds. Spider lightning is often linked to +CG flashes.
A cloud to ground lightning strike begins as an invisible channel of electrically charged air moving from the cloud toward the ground. When one channel nears an object on the ground, a powerful surge of electricity from the ground moves upward to the clouds and produces the visible lightning strike.
While no place is 100% safe from lightning, some places are much safer than others. The safest location during a thunderstorm is inside a large enclosed structure with plumbing and electrical wiring. These include shopping centers, schools, office buildings, and private residences.
Remember the phrase, “When thunder roars, go indoors.” Find a safe, enclosed shelter when you hear thunder. Safe shelters include homes, offices, shopping centers, and hard-top vehicles with the windows rolled up. Seek shelter immediately, even if caught out in the open.
Lightning often strikes water, and water conducts electricity. That means that the currents from a lightning strike can seriously injure you. In fact, it can even kill you. This is why, when you hear thunder or see lightning, it's a good idea to avoid the pool, beach and any other large body of water.
There are three common types of lightning: cloud to ground, cloud to cloud and cloud to air. Cloud to ground lightning is the most dangerous. The ground is mainly consisted of positively charged particles while the bottom of violent storm clouds have negative charged particles.
When You See Lightning, Count The Time Until You Hear Thunder. If That Is 30 Seconds Or Less, The Thunderstorm Is Close Enough To Be Dangerous – Seek Shelter (if you can't see the lightning, just hearing the thunder is a good back-up rule). Wait 30 Minutes Or More After The Lightning Flash Before Leaving Shelter.

What is the rarest type of lightning?
ball lightning, also called globe lightning, a rare aerial phenomenon in the form of a luminous sphere that is generally several centimetres in diameter.
Lightning can travel 10 to 12 miles from a thunderstorm. This is often farther than the sound of thunder travels. That means that if you can hear thunder you are close enough to a storm to be in danger of being struck by lightning.
“Simply go to a large, substantial building or a fully enclosed metal-topped vehicle.” A lightning-safe structure is one that has grounded wiring and plumbing, like most homes and buildings in the U.S. Places like tents, sheds, dugouts and picnic shelters are not safe from lightning strikes, according to experts.
No. Lightning can travel through plumbing. It is best to avoid all water during a thunderstorm.
You may also feel a physical tingling sensation throughout your body, especially in your extremities. This is often the gut feeling that people get when they "sense" that something is impending. If your hair is standing up, you may have only a few seconds to protect yourself from lightning.
But the odds of being struck by lightning in a given year are less than one in a million, and almost 90% of all lightning strike victims survive.
Myth: If you are in a house, you are 100% safe from lightning. Fact: A house is a safe place to be during a thunderstorm as long as you avoid anything that conducts electricity. This means staying off corded phones, electrical appliances, wires, TV cables, computers, plumbing, metal doors and windows.
Reaching up to 50,000° F, lightning bolts are so hot that they can heat your home's roof, shingles, and attic enough to cause a major fire. A direct hit can even punch right through your shingles and into the attic beneath, causing damage to the electrical systems, insulation, and more.
Thunderstorms are electrically charged. Umbrellas mostly contain metal parts which are good conductors of electricity. The electric charge form thunderstorm can move into the umbrella and cause harm to the person carrying it. Therefore, it is nor safe carrying an umbrella during a thunderstorm.
Summer is the season for thunderstorms, and sometimes lightning can strike an aircraft that is flying. However, a lightning strike on an aircraft is not dangerous, as aircraft are designed to withstand lightning strikes.
What happens if lightning strikes the ocean?
When lightning strikes, most of electrical discharge occurs near the water's surface. Most fish swim below the surface and are unaffected. Although scientists don't know exactly just how deep the lightning discharge reaches in water, it's very dangerous to be swimming or boating during a thunderstorm.
If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you'll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close.
A recent analysis from the World Meteorological Organization (WMO) found that a single flash of lightning along the northern Gulf Coast spanned 477 miles across, breaking a world record. This megaflash of lightning lit up an area stretching from Texas to Mississippi.
Weather.gov > Safety > Heat Lightning. The term heat lightning is commonly used to describe lightning from a distant thunderstorm just too far away to see the actual cloud-to-ground flash or to hear the accompanying thunder.
Does lightning strike from the sky down, or the ground up? The answer is both. Cloud-to-ground (CG) lightning comes from the sky down, but the part you see comes from the ground up. A typical cloud-to-ground flash lowers a path of negative electricity (that we cannot see) towards the ground in a series of spurts.
Most deaths after lightning strikes occur either because of primary cardiac arrest or hypoxia-induced secondary cardiac arrest.
Dark lightning is the most energetic radiation produced naturally on Earth, but was unknown before 1991. While scientists now know that dark lightning naturally occurs in thunderstorms, they do not know how frequently these flashes take place or whether visible lightning always accompanies them.
Sometimes lightning may be seen but there is no thunder heard. This is either because thunder is rarely heard more than 20 km away or because the atmospheric conditions lead to sound bending upwards and away from the surface.
A bolt of lightning is damaging enough on its own. It can puncture a roof, sear the surrounding materials, and tear through attics. A powerful enough strike can tear off shingles and gutters, leaving the roof a disaster.

How many times can you survive getting struck by lightning?
Of every 10 people struck, nine will survive. But they could suffer a variety of short- and long-term effects: cardiac arrest, confusion, seizures, dizziness, muscle aches, deafness, headaches, memory deficits, distractibility, personality changes and chronic pain, among others.
White: most powerful lightning color
White is the most dangerous color of lighting. It suggests both a low concentration of moisture and a high concentration of dust in air.
Perhaps the strangest colors reported are instances of pink or green lightning seen during snowstorms. The phenomenon, known as”thundersnow”, is rare. The unique sky color is caused as snowflakes refract and reflect the white bolt in a unique way.
Typically, blue lightning within a cloud indicates the presence of hail. Red lightning within a cloud indicates the presence of rain. Yellow or orange lightning occurs when there is a large concentration of dust in the air. White lightning is a sign of low humidity or a little amount of moisture in the air.
The average hurricane moves from east to west due to the tropical trade winds that blow near the equator (where hurricanes start). When a hurricane is still in the Caribbean, the tropical jet blows east to west, and the hurricane moves west to gain power.
The prevailing wind direction here across the U.S. is from west to east, which explains why most storm systems move in that direction. However, depending on certain factors, such as jet stream placement and positioning, some storm systems can move from south to north, and even east-to-west!
Myth: Thunderstorms and tornadoes always move from west to east. how and where storms will move, and it can be in any direction.
In Florida — where some counties have the highest concentration of lightning in the U.S. — the Gulf of Mexico and Gulf Stream blanket land with moist, warm air. Along the West Coast, it's a different story. The cool marine layer keeps air from rising.
The reason that they most often move from west to east is due to the jet stream. The jet stream is a narrow band of fast, flowing air currents located near the altitude of the tropopause that flow from west to east. The jet stream flows around the entire earth.
Storm surge is greatest on the eastern side of a hurricane too. The faster winds on that energized "right side" of the hurricane create higher waves, slightly higher wind gusts and the storm surge.
What direction do most storms move?
This segment of weather 101 focuses on storm motion and why we generally see storms move from west to east. The easiest answer is the jet stream. In the United States, the wind above our head tends to move in a direction from west to east. These act to steer our storms and move them across the country.
The reason is something called the Coriolis effect, or Coriolis force, named for the French mathematician Gaspard-Gustave de Coriolis, who published work on the effect in the 19th century.
In the northern hemisphere, specifically in the United States, our prevailing winds blow from west to east in conjunction with Earth's rotation. This causes storms to move in that same direction along the jet stream.
There is no one direction the wind comes from when thunderstorms or tornadoes occur. Where warm moist air is forced to rise by hills, mountains, or areas where warm/cold or wet/dry air bump together, thunderstorms can form.
The sun heats the land unevenly during the day, and when the heating from the sun stops at night, changes occur in the atmosphere that force a strong "jet" of air just above the ground.
However, after a thunderstorm passed through the area, the downdraft dropped the temperature to a cool 57 degrees by 5:00 P.M., a 40 degree temperature swing in one hour! However, most storms cool things off a more modest 10-15 degrees because of evaporative cooling.
On warm days, shorter wavelengths of blue light are scattered quickly, leaving the sky with vivid colors on the yellow-orange-red end of the spectrum. As a result, the same process that initiates brilliant colors at sunset makes the sky turn orange or yellow when a storm is brewing.
