Lightning Types: In cloud-to-ground lightning (CG), a stepped leader, will zigzag downward in roughly 50-yard segments in a forked pattern. This stepped leader is invisible to the human eye. A return stroke of bright luminosity travels about 60,000 miles per second back towards the cloud. A flash consists of one or perhaps as many as 20 return strokes. Cloud flashes sometimes have visible channels that extend out into the air around the storm but do not strike the ground, known as cloud-to-air (CA). The terms sheet lightning or intra-cloud lightning (IC) refers to lightning embedded within a cloud that lights up as a sheet of luminosity during the flash. Lightning can also travel from cloud-to-cloud (CC). Large thunderstorms are capable of producing other kinds of electrical phenomena called transient luminous events (TLEs) that occur high in the atmosphere. They are rarely observed visually and not well understood. The most common TLEs include red sprites, blue jets, and elves. Ball lightning is a rare and randomly occurring bright ball of light observed floating or moving through the atmosphere close to the ground. Observations have widely varying identifying characteristics for ball lightning, but the most common description is that of a sphere having a radius of 15–50 cm, orange or reddish in color, and lasting for only a few seconds.

 

Lightning Mapper

Facebook
Did you know that GOES-16 (a satellite that orbits the Earth) houses the very first operational lightning mapper flown in geostationary orbit? GLM measures total lightning (in-cloud, cloud-to-cloud and cloud-to-ground) activity continuously over the Americas and adjacent ocean regions with near-uniform spatial resolution of approximately 10 km. #GLM http://www.goes-r.gov/spacesegment/glm.html

The Geostationary Lightning Mapper: The first operational lightning mapper flown in geostationary orbit. Provides critical information to forecasters, allowing them to focus on developing severe storms before they produce damaging winds, hail or tornadoes.

 

When Thunder Roars, Go Indoors!

Facebook
When Thunder Roars, Go Indoors! Thunderstorms can produce deadly lightning capable of striking up to 10 miles away from the storm — so, even if you don't see rain you could be in harm’s way. Remember this simple message: When Thunder Roars, Go Indoors! weather.gov/lightning #LightningSafety #SummerSafety

Twitter
Thunderstorms can produce deadly lightning strikes up to 10 miles away. weather.gov/lightning #LightningSafety

When Thunder Roars, Go Indoors! STOP all outdoor activities. Seek shelter in a building or hard-topped vehicle. Wait 30 minutes after you last hear thunder to resume activities.

Boating Safety

Facebook
Thunderstorms can be a mariner's worst nightmare. They can develop quickly and can produce strong wind, pounding rain and deadly lightning. If you see clouds beginning to pile up, thunderstorms are likely beginning to develop. Don’t wait until you can hear thunder or see lightning. It is best to head to port or safe shelter at the first sign of a developing storm. weather.gov/safety/safeboating-during #LightningSafety

Twitter
Boaters: When storms start to form, head to port or safe shelter immediately! weather.gov/safety/safeboating-during #LightningSafety

Get to safety if the weather looks threatening. Thunderstorms pose a hazard to mariners. They bring dangerous wind and lightning. Head to land at the first sign of a storm.

 

Beach

Facebook
Whether you’re spending the day at the beach or an afternoon at the pool, at the first sign of a storm, you should gather your things and seek shelter. By the time you hear thunder or see lightning, you’re already in danger. When Thunder Roars, Go Indoors! weather.gov/lightning #LightningSafety #SummerSafety

Lightning Do's and Don'ts. DO: Go inside when you hear thunder! Find a sturdy house, building, or car with a roof. Stay indoors for at least 30 minutes after you last hear thunder. DON'T: Retreat to dugouts, sheds, pavilions, picnic shelters or other small structures. Use or touch electronics, outlets, corded phones or windows. Go under or near tall treesd, swim or be near water, stand near metal objects.

 

Safe Fishing

Facebook
Going fishing? Be aware of the dangers of lightning while out on the water. A lightning strike to a vessel can be catastrophic, especially if it results in a fire or loss of electronics. Boaters should use extra caution when thunderstorm conditions exist and have a plan of escape. weather.gov/lightning #LightningSafety

Twitter

Safe Fishing: Understand the dangers of lightning. There are no specific warnings or advisories for lightning but all thunderstorms produce lightning. A lightning strike to a vessel can be catastrophic, especially if it results in a fire or loss of electronics. Boaters should use extra caution when thunderstorm conditions exist and have a plan of escape.
