Flash flood warnings are up in the US this year — Here’s where The 3,722 flash flood warnings that occurred between Jan. 1 and July 30 are a record high for the time period going back to 1986.

Warming atmosphere combined with factors like socioeconomic conditions, land use, and land cover increase the risk of flash floods, which will continue to grow and evolve in the coming years, says @ncdp.bsky.social climate scientist @wxpizza.bsky.social. Via @wvtm13.bsky.social.

There needs to be strong local attention to the fact that disasters don't affect people evenly, they don't recover evenly, and some people are going to need more help than others, noted Jeff Schlegelmilch.

Why Flash Flooding Is Getting Worse and How to Stay Safe Flash floods are occurring across the U.S., from Texas to New Jersey. Here's what you should know as risks escalate.

Why are flash floods getting worse, and how you can best stay safe? Experts Jeff Schlegelmilch of @ncdp.bsky.social and Jason Smerdon of @climate.columbia.edu and @lamont.columbia.edu explain. Via TIME. time.com/7302498/flas...

What should you do in a flash flood? Expert safety tips for before, during and after Flash floods can start suddenly and become dangerous quickly. But there are steps you can take to protect yourself, both in the moment and well in advance.

✨ @jonathansury.bsky.social talks with @npr.org about what to do before, during, & after an emergency. He recommends:
1. Knowing your risk.
2. Having an emergency preparedness plan.
3. Sharing that plan with your household.
4. Setting up multiple ways of receiving weather alerts.
