The Geostationary Lightning Mapper

Facebook
Did you know that weather satellite GOES-16 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.
When used in conjunction with radar data, GLM trends allow forecasters to make warning decisions earlier and more confidently.

The Geostationary Lightning Mapper. GLM measurements help the weather, aviation, disaster prep, and fire communities with early warning of lightning strikes, identifying storm intensity, tornado lead times and false alarm reduction, and detection of heavy rainfall and flash flooding.

 

Your Safe Place from Lightning

Lightning strikes the U.S. 25 million times a year, which sometimes results in death or permanent injury. You are safest indoors, or inside a hard-topped enclosed vehicle. Stay Weather-Ready and learn more about lightning safety: weather.gov/safety/lightning

Survivor Story: Boating

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.

 

When Thunder Roars, Go Indoors!

Facebook
Lightning strikes the United States about 25 million times each year! Thunderstorms 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/safety/lightning

Twitter
Thunderstorms can produce deadly lightning strikes up to 10 miles away. When Thunder Roars, Go Indoors! weather.gov/safety/lightning #WeatherReady

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.

Safe Fishing

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.

Boating Safety

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

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

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 Lightning

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/safety/lightning

Camping

Facebook
Going camping? You are NOT safe from lightning in a tent. Avoid standing under trees. Find a sturdy building for shelter. If you can’t find one and are near your hard-topped vehicle, shelter in it with the windows up.
