Crazy Storm Weather and Lightning - Global

Crazy storm weather in Croatia

Due to the approaching high-altitude cyclone and the influx of moist, unstable air, the State Hydrometeorological Institute (DHMZ) has issued a red warning for the Zagreb, Karlovac and Rijeka regions, while the rest of the country is under an orange warning.

Severe thunderstorms, heavy rain, possible hail and a sudden drop in temperature are expected during the evening and night, the DHMZ warns.

In Karlovac, 48.2 millimeters (1,9 inches) of rain fell on Sunday between 0:00 and 08:00. For comparison, the average amount of precipitation in that city during July is 92 millimeters (3,6 inches). If we add to that figure Saturday's precipitation - between 08:00 and 00:00, 16.6 millimeters fell - the total amount of rain in 24 hours is slightly less than 65 millimeters (2,5 inches).
Also hail in Karlovac:

And the memorable scene was filmed in Istria. During a storm in Jehnići near Poreč, residents could see an incredible palette of colors in the sky while lightning flashed.

In Zadar, on Saturday between 21:00 and 22:00, 20.3 millimeters of rain fell, which is more than half of the average July precipitation in that city, which is 35.4 millimeters.

Megaflashes! New records set for longest lightning strikes, both in length and duration​

Story Summary

• The new record for longest lightning strike is now 477 miles, set on April 29, 2020.
• The new record for longest-duration lightning strike is just over 17 seconds.
• “These are extraordinary records from single lightning-flash events."

Scientists in Europe on Monday confirmed that a pair of lightning strikes in 2020 set new world records, for both length and duration.

Apparently there is a new megaflash event that happened in 2017 that beats this record. It apparently extended from eastern Texas to near Kansas City, Missouri on Oct. 22, 2017 reaching 515 miles (+/- 5 miles)!

A New WMO-Certified Single Megaflash Lightning Record Distance: 829 km (515 mi) occurring on 22 October 2017

Abstract The World Meteorological Organization has recognized a new world record lightning discharge distance of 829 km ± 8 km (515 ± 5 mi) that extended from eastern Texas to near Kansas City MO USA within a 22 October 2017 thunderstorm complex.

Over the weekend we had crazy weather on the Mid North Coast NSW, Hunter region and the Tablelands. Floods, wild winds and snow where it rarely snows:

A 26-year-old woman is still missing in floodwaters and evacuation orders have been issued for flooding in parts of New South Wales following torrential rain, wind and heavy snow.

Strong storm hits Mexico City, the International Airport (AICM) closed for several hours, floods at many places, the Zocalo flooded (first time I had seen that) several hisotrical buildings with water leaks. And the forecast is that heavy rain will continue in most of the country.

Mexico City International Airport (AICM) suspended landing and takeoff operations due to heavy rain. The rainfall affected safety and visibility on the runways, causing flooding. The AICM recommends that travelers contact their respective airlines to find out the status of their flights.

Rainfall on August 10 causes damage to La Merced Parish
The historic church located in Arcos de Belén, in the center of Mexico City, was flooded inside. Workers and parishioners joined forces to remove the water and move the parish furniture, trying to prevent further damage.

The extremely heavy rain that hit Mexico City on Sunday caused severe flooding in the capital's Zócalo. The water level even reached the Metropolitan Cathedral and several businesses.

Is not the first time, though...

Today's rain reminded me of the worst flood that hit Mexico City in the 20th century; it was the afternoon of July 15, 1951. A brief THREAD. That year, a storm caused two-thirds of Mexico City to be flooded, with the lowest areas covered by up to 2 meters of water!

And we should not be surprised much, though. Mexico City was built over a lagoon,

Why does Mexico City flood?
WATER HOLDS MEMORIES...
Work by Miguel Covarrubias

The song performed by Jorge Negrete in the film "I'm going to eat that prickly pear." famous for several decades, which is already ingrained in the collective memory of all Mexicans, especially those who live in Mexico City, is very fitting.

I'm going to eat that prickly pear.

The little tree where the peacock slept has fallen
Now it will sleep on the ground
like any other animal.

The eagle, being an animal, was depicted on money
to climb the prickly pear cactus
it asked permission first.

Guadalajara on a plain, Mexico on a lagoon
I'm going to eat that prickly pear
even if it pricks my hand.

They say I'm a bad man, bad and ill-fated )
because I ate a peach
with a red heart.

Weather chaos in Paris diverts flights and causes cancellations due to lightning and cyclonic wind activity.

Due to the significant turbulence due to the gusts of wind, the evening's flights to Calvi from Orly and Marseille were diverted to Nice and Bastia respectively. "The flight to Bastia from Orly scheduled for 8:00 p.m. was initially diverted to Nice and had to return to Paris this evening," according to a statement from the Corsican prefecture.

Vancouver Island experienced some amazing lightening and thunder last night.
I live on the very southern peninsula, and the storm was mid island north of us, so didn’t get to see the show in person, but I managed to collect a few photos.
The bolts of lightening seemed to be very “plasma” looking on a couple of them. There were a few videos, and they showed the same thick, blob type bolts, so it possibly wasn't lens distortion.






The amount and intensity of recorded lightening bolts is incredibly high for the pacific coastal area.

Over 4,500 lightning strikes hit California overnight, sparking new wildfires.
By Gillian Mohney, News Editor, Sep 2, 2025

Thousands of lightning strikes were reported Tuesday in the East Bay and Central Valley as dry thunderstorms rolled through the area, increasing the risk of a major wildfire.

The National Weather Service reported more than 4,700 lightning strikes from midnight to 5:30 am Tuesday, with minimal precipitation, in an area stretching from Paso Robles to just north of Sacramento.

Cal Fire reported four new fires in the Central Valley on Tuesday morning but has not said if they were caused by lightning.
Roger Gass, a meteorologist at the National Weather Service, said the lightning strikes will continue as the storms head east into the Sierra Nevada.

“We have a greater potential … during the summer months to have these dry thunderstorms, as monsoon moisture works its way in from the desert southwest and generally just to our south,” Gass told SFGATE.

Dry thunderstorms can be particularly dangerous, as heat and arid weather leave plenty of fuel in the form of dried vegetation in California hills in the late summer and early fall months. In August 2020, two days of storms ignited 367 fires in California.

Parts of Southern California including Palm Springs and San Bernardino are also seeing stormy conditions. A social media post on X showed showers and lightning in the Palm Springs area Tuesday morning.

Gass said the Bay Area may avoid a major wildfire, as temperatures are expected to drop this week, helping mitigate the fire danger.

“We are expecting a cooling trend throughout the week,” Gass told SFGATE. “Temperatures will generally cool to around or just below seasonal averages, and as we head into the upcoming weekend, they basically hold steady.”

But the risk of wildfire remains high for parts of the state. The weather service has issued a red flag warning for regions of far Northern California along the Oregon border through Wednesday.

It is highly likely that the windy phenomenon that struck Morbihan this Tuesday morning was a tornado. Several municipalities suffered damage along a narrow corridor. Here, roofs torn off in the Kerchevet hamlet in Guéhenno. (via @Gazettedu56

Line 1
A ridge regime largely dominated during the summer, with a fairly strong anomaly of high geopotentials over western Europe.Lower down in altitude, the air mass exhibited an anomaly of nearly 2°C at 850 hPa.

Over the summer, more than 4000 severe hailstorms were recorded, a value down compared to last summer. The south of the country was more exposed to these hailstorms. Find the detailed report for the summer of 2025 here: https://keraunos.org/actualites/fil
