Having lived in both Palm Beach County and St. Lucie combined for almost 10 years 98-2007, and having been through Georges, Irene, Frances, Jean and Wilma I have never heard such a noise as on the OP video clip. At one point during the clip it almost sounds like a hum in the background in addition to the rumbling as if some type of mechanical/engine related machine/device, just a guess though. This is VERY weird and surely would have made me soil my trousers a bit had I been there 1st hand. Thanks to OP for posting this! Keep us informed if anything else happens. Indeed some very strange things have been happening lately. I really wonder sometimes if "they" can control the weather?! S&F..

ATS! I live near Waterford, Michigan and I just heard a similar noise to the one posted by the OP. Unfortunately, by the time I got to my camera, it of course got quiet before fading away. It lasted only about 4-6 minutes, and from my perspective it sounded almost machine like or fake thunder on a TV show. Very strange to say the least. I will try and catch it on video if it happens again, anyone else near that area hear anything? About 3:38am or so.

I also heard a loud rumbling noise like that several years ago here in TN, it lasted about 5 mins or so but it sounded like a huge, very low flying airplane. Some years later I saw a show that pointed out a odd contrail they were attributing to the Aurora,that was not far from where I live.

Been lurking around this site for a few months.....ok... not meaning to revive a somewhat dead thread but I felt I needed to post this. I'm just a regular guy from a little town in north carolina. I'm open minded and believe that we are not alone (i think this is common sense considering the countless galaxies in this fascinating universe). I've only had one encounter with a ufo in my lifetime (I'm 26). I was at my cousin's house on his front steps waiting for him to unlock the door. Both my cousins where looking at the house and I was sorta looking to the side and out of my peripheral I seen what looked to me like a shooting star except this object was coming straight down. This thing was blazing fast but what was so weird was before it disappeared behind the tree line it slowed for like a split second (not like a dead stop but very noticeable) and BOOM gone... all this lasted like 3-5 seconds... scared the living ish outta me.... I tried telling my cousins what I saw and they just looked at me like I was crazy. I really wish I would've been quicker with my reactions because I would have alerted them but it shocked me to the core and left me stupefied to the point of WOW I really just saw a ufo. I dont equate ufo to aliens automatically but the fact is it's still unexplainable. This happened about a year ago.

Anyways... just felt I needed to discuss my history with unexplained things. Now what happened to me two days ago pertains to this thread. I had no idea about the worldwide rumbling and noises so I felt I needed to add my account to this phenomenon. I was laying in bed watching a movie.... just a normal night winding down... when all of a sudden I felt this slight rumble.... that grew to the point where it got scary. I put my hand flat on my bed and could feel it definitely... this was NOT my imagination. It felt like an old raggedy dryer was bouncing around except I dont have an old raggedy dryer and my perfectly fine dryer was definitely off. I shook it off but it still left me confused as hell. Perfectly clear night no storms... nothing. It lasted maybe 30 seconds.... and after it I went outside to see if anything "unusual" was afoot there was nothing but I could definitely hear my neighbor's dogs barking like it was no tomorrow.... very creepy indeed.

Another incident before this was sometime during the summer I went to go pay respects to my grandfather at his grave site. Well the grave site is about 10-15 minutes from where I live...When I got in the car I didn't hear anything out of the ordinary. When I arrived at the grave site I got out and to my astonishment I could hear a very weird noise in the distance. It sounded like howling wind but it definitely had a mechanical tone to it (if that makes sense). Like it was familiar and unfamiliar at the same time. It creeped me out. This sound also had a feeling behind it (if that makes any sense). Like a slight pressure (as if my ears were gonna pop). The mechanical tone let me know that it definitely was NOT the howling wind.... plus it wasn't windy at all that day. I was at my grandfather's grave site saying in my head "WTF is that sound" over and over and over. It distracted me to the point where I left earlier than expected with my last words to my grandpa being "please guide me and I love you". What also confirmed the creepiness was when I talked to some family that live like 2-3 minutes from the grave site they also said they heard the weird sound.

I don't know... but I feel something REALLY big is about to happen. Friends and fellow humans PLEASE keep your eyes, ears, and minds open.
