Houston's road grid… but make it clouds. The satellite imagery from Tue morning was genuinely something I've never seen before. So my producer @monsoonchaser and I took a stab at explaining it #wxtwitter
Captured some upward lightning emanating out of a few of the wind turbines near Rufus, Oregon yesterday evening as the main line of storms drifted into the eastern slopes of the Cascades. #orwx#wawx
This powerful bolt of lightning shot out of the sky near Spearman, TX. I was using the new @_BoltHunter that @Negative_Tilt designed. I was lucky enough to capture seven different images out of this same bolt. ⚡️ ⛈️ #txwx#pnw#chaser#lightning
Finally, here is the list of geomagnetic storms stronger than the 10-11 May 2024 G5 Gannon superstorms since 1859, based on the estimated minimum DST index. The list of storms is likely somewhat incomplete for the 19th century and likely complete for the 20th century. In the last 168 years there were at least 14 storms stronger than the May 2024 event. This means that on average (!) we get:
- a storm with DSTmin < -400 nT about once every cycle
- a storm with DSTmin < -500 nT about once every two cycles
- a storm with DSTmin < -600 nT about once every three to four cycles
- a Carrington level storm (DSTmin < -800 nT) about once every 50-70 years or every five cycles or so
Interestingly enough there was only one event with DSTmin < -500 nT in the last 80 years.
Incredible crawlers last night with the severe storms in Kansas, I was on 3 tornado warned storms, 80mph straight line winds with bow echo. Pretty rad day into the early morning hours. 🤯 ⛈️ ⚡️ #kswx#pnw#chaser
