Just went gangbusters. That is one of the most vulnerable watersheds in Montgomery County. Terrain, loose soils and urbanization are tremendous stressors on that waterway.

That was from one of our county flood sensors near Sligo Creek Pkwy & New Hampshire Ave (MD 650). I've never seen water levels rise that quickly at that location. I actually wound up requesting the upgrade to a flash flood emergency. Our flood sensors inside the beltway just went bonkers so fast. Cabin John Branch, Rock Creek, Sligo Creek, and Northwest Branch just started raging in under half an hour. This was the worst flash flood event I have ever worked in my entire career. Had this persisted for just another 20 to 30 minutes, we would've had real problems in Montgomery County. The flood sensors we installed, combined with the Layhill and College Park mesonet sites raised alarm bells quickly, which resulted in us getting roads closed and water rescue assets staffed quickly. It was one of the few times in my career that I actually felt helpless as things went sideways.

Wow that cluster of storms running along the topside of the DC Beltway is nasty.

^preview of Winter 2025 - 2026? Maybe we'll get whacked?

Agreed. Some three or four day stretch of dry mid 90s heat that just feels like a crisper.

Nearly five inches of rainfall this month. RSTM2 COOP site. Impressive.

Going down to Chincoteague August 2nd to 9th. Just need some hot, sunny weather.

Tornado Warning NE Carroll County

what creek?

Spotty, but slow moving and intense storms today. Once again, I believe the watch is justified.

Got a screen cap?

4.77" for the month. Incredible. Bye bye drought.

NYC metro crushed. Legit flash flood emergency up there.

Incredible gradient. M1.83" Layhill mesonet site, only M0.09" Clarksville.
