Kicking off in cork city now

Judging by the reports here and observing the detectors, clearly not picking up all the flashes .

Very bright flash and a loud rumble of thunder and then a kind of secondary one(might not be the correct term for it) and this might be a stupid question but is that thing of counting the seconds between a flash of lightning and thunder based on anything solid or is it just a rough guess of how far away it was ? I've always wondered that and given we have thunder and lightning right now it's as good a time as any to ask.

Another one. The power goes off for a brief second.

I think it's a rule of thumb

Noticed that too, lightningMaps.Org seems to be the best atm.

Lots of flashes.
Less thunder though.

Just the difference between the speed of light and the speed of sound.

igCorcaigh

All the car alarms going off.

Gave me a giggle.

To expand, sound travels at around 343m/s (and light at 300,000,000m/s) so for every 3 seconds between the flash and the thunder, the cloud that caused it is around 1km away. In 3 dimensions mind - could be vertical.

Hmmm the whole grid dimmed there. its under pressure

Power flicked here too.

Got a light flicker here in South Dublin too, must've been a strike that hit a major part of the grid for it to be so noticeable around the country.

pauldry

Yes can confirm lights flickering Castlebar

Hope this isnt a 6 month el nino type monsoon about to begin

August another washout.
