This is a clear example of a compound hazard event (i.e., amplified societal impacts). Severe thunderstorms knocked out power for nearly 250,000 people last night, and many are now seeing near-record heat today while still without electricity.

The World Cup has cooling breaks. Latino neighborhoods don't | Opinion
Millions will experience this World Cup in dangerous heat in dense NJ and NY neighborhoods, with no hydration breaks and no one looking out for them.

Did I hit the target on why people are dismissive of extreme heat warnings in summer, but all ears on extreme cold warnings in winter? Let me know your thoughts on what I wrote.

This is far from normal...and deadly for a place where many homes have no AC....This is climate change. Europe isn't supposed to experience triple digit heat like this anytime and especially in June

Not only are these 100°F+ temps brutal for June in Europe: the heat wave's even more dangerous because of its prolonged nature and the relatively moist air (dew points above 70F in some cases) leading to "tropical nights." @climateconnections.bsky.social

Extreme flash flooding occurred in Louisiana today, where localized but prolonged training convection led to over 2 feet of rain per MRMS estimates.
While isolated, this was supported by synoptic-scale moisture flux convergence from a slow-moving mid level vortex moving onshore.

Hope the next 10 days don’t end up as bad as it looks on paper. Fuels in the Apps and Mid-Atlantic are pre-conditioned by drought and recent high-end drying. An April heat wave on top of already historically dry fuels, unusually dry air and periods of gusty winds could bring major fires this week.

Most people won't see me or Matt or @weatherwest.bsky.social or @katharinehayhoe.com talking about the value of NCAR or NCAR has done to make us all safer from the weather.
But you know who people would see? Their local weathercaster.

I also tried to connect real-world & first-hand examples of NCAR's value to the field here. We really need folks with platforms stepping up and speaking out about this. It's bad for all of us.

Record heat now outnumbers record cold by more than 3 to 1 in the US. In a normal climate, they’d be equal. After billions of years of natural hot & cold cycles, human forcing has now overtaken nature as the longterm driving force of our present & future climate.
