Heavy radio interference today

Wasn't sure where to put this as there is no FM signal section I thought some of you HAM operators could explain this to me.

Yesterday and today while driving to work I notice there is a ton of radio interference in all stations. Today was much worse than yesterday.

I could barely hear the station I normaly listen to through the other station bleeding into it. I could clearly make out the songs it was playing over top of sports Station.

When I got to work my normal station was completely drown out and it was like I was just listening to this other station clear as a bell. I decided to sit and listen until someone gave the call again of this intruding station to see where it was because I knew it wasn't anything local. As soon as the current song was finished they began news and I found they were out of NORTH CAROLINA. How in the hell is that possible. This was FM station not am.

I understand interference when you're getting to far from the station and the next station is bleeding in as you get closer. However The normal station I was trying to listen to is out of baltimore, Probably 30 miles away. They advertise that they broadcast at 50 thousand watts. And the other was in NC

Matt - KP index (which measures geomagnetic disruption level) has been pretty quiet the last three days. I wouldn't expect the interference to be in relation to geomagnetic storms or anything similar.

I didn't notice any disruption here and nobody else commented that they had the same issue, so it's probably not an atmospheric issue. Seems localized. Beyond that I'm not sure...

That's interesting. It's still happening and I've noticed it's in other channels aswell. Meaning the other channels are picking up interference aswell.

Hmmmmm. Beyond My Ken.... especially when other transmissions on radically different Frequencies and Modes are experiencing difficulty as well.

Maybe ALIENS?😎

Can anyone tell me why my cellphone works perfectly when I’m in the turret area of my tower at work?
Surrounded by steel walls, floor and ceiling.
Does not portend well for electronics shielded in a trash can for EMP protection.

The frequencies used are kinda flukey and beamy. Can reflect on a surface or come in through a window or open door, especially since you are aloft, with better "view" of Cell towers - less terrestrial impediments...

My guess anyways.

Funny. That’s what the PhD engineer said.
Hatch door to outside was open so he figures its reflecting around all the metal surfaces inside. Wants me to try it with the door closed next time. See how much signal I have then.
Very scientific. 🤣

BTW. On the OP.
There’s days up here when the radio spectrum in general is just trash. AM, FM, VHF, UHF, and the ham bands. Doesn’t appear to be local weather. Although that’s certainly the case sometimes.
