Around 5:30 p.m., tornado warnings were issued for Brooklyn, Queen and Staten Island. While it's unclear whether a tornado did touch down (the National Weather Service's Doppler Radar indicated a tornado did touch down in Brooklyn or maybe on/near Staten Island), many people noted hail and the sky turning an ugly green before sheets of rain pounded the city. Numerous trees have fallen, causing street closures, accidents and mass transit delays. After the jump is our liveblog coverage with videos and you can share your photos and videos with us—just email them to photos@gothamist.com or tag them "gothamist" on Flickr—we'll be updating our post throughout the night.

The Office of Emergency Management issued alerts for this crazy weather, "Alert issued 9/16/10 at 5:35 PM. The National Weather Service has issued a Tornado Warning until 6:00 PM in Staten Island and Brooklyn. Immediately go indoors and/or to the lowest floor of your building for shelter. Stay away from windows," and "Tornado Warning issued for Queens until 6 PM. Take shelter on lower floors. Stay away from windows." There's definitely hail hitting in Brooklyn.

Update: Was there a tornado? National Weather Service says, "AT 529 PM EDT... NATIONAL WEATHER SERVICE DOPPLER RADAR CONTINUED TO INDICATE A TORNADO. THIS TORNADO WAS LOCATED NEAR PARK SLOPE... OR NEAR VERRAZANO-NARROWS BRIDGE... MOVING EAST AT 30 MPH."

Update 5:58 p.m.: The Twitterverse is FREAKING OUT about the tornado in Park Slope. "Tornado warning in Park Slope? Literally in my neighborhood! It's SO crazy outside right now!!" (via) and "Tornado just touch down Park Slope.. Tht was very amazing to see.." (via). But one person Tweeted for more backup, "There was a tornado in Park Slope?? Lesbians - please confirm!"

And a commenter just sent us this video of the storm in Clinton Hill:

You can share your photos with us—just email them to photos@gothamist.com or tag them "gothamist" on Flickr. Anyone see funnel clouds?

Update 6:13 p.m.: Because of downed trees in Queens, Long Island Rail Road service is affected—which means Penn Station is a mess with delays. Find out more at the MTA website. We're also hearing a roof was torn off of a Brooklyn building and that there are numerous trees downed in Brooklyn, too. Also, trees have also fallen on some vehicles on the highways in both Queens and Brooklyn.

Update 6:36 p.m.: We hear that someone in a vehicle on the Grand Central Parkway, where many trees fell onto cars, died from his/her injuries. Also, there are many issues with subways due to debris on tracks, etc.—check MTA website for more details.

Update 6:59 p.m.: We're hearing about numerous "tree vs. house/building" and "tree vs. car incidents"—one driver is trapped in his/her car. Also, we heard something about a "roof onto a MTA bus."

Also, thanks for your photos and videos. We've added some more and we'll continue to update them throughout the evening.

Update 7:39 p.m.: Joe Schumacher tells us, "I'm not a severe weather expert but it looks more like straight line winds, a gust front, than a tornado. The weather service will have to check out the damage patterns tomorrow to know for sure."

And here's another video from Brooklyn:

Update 9:45 p.m.: The NY Times reports that it's not declared a tornado yet, though it sure seemed like one, "The fast-moving storm, which had initial wind estimates of 60 to 80 miles per hour, uprooted hundreds of trees in parts of Staten Island, Brooklyn and Queens, and there were numerous reports of small fires, power failures and damage to homes, stores and vehicles." Also Mayor Bloomberg, who took at a look at some damage in Queens, said that schools would probably be open tomorrow, "While it may be an act of god, doesn’t make it any easier for us. The good news is that most people were safe, just annoyed, with traffic being bad, or a tree coming down in their yard."

If you need to report downed trees or structural issues, call 311. (The FDNY and EMS have been responding to a high number of calls via 911.)

And we've updated with more photos (the last two rows of photos) and here's another video from reader Jesse:


Update 10:20 p.m.: Reader Laura just commented with her account of the storm in Queens:

The news is missing so much of the story - Middle Village along St
John's Cemetary and Juniper Valley Park looks like a war zone. There
was a 3 bus line up on Dry Harbor Road. A bus on Penelope Ave and Dry
Harbor Road was hit by a London Plane tree - the driver by his bus
looked shocked. The storm hit at 5:50 to 6:00 - rush hour.
I was on Furmaville Avenue - traveling west in my BMW. I looked to
pull my car over as the sky grew dark, and then almost black but
glowing. Looking for a spot free of trees - this area of Middle
Village has tudor homes and 80 year old trees. As I was pulling off
the road I saw a wall of darkness against a soft grey light - it had to
be a tornado - or a sheer. It was coming from the East - and I could
not understand what direction the wind was coming from. A branch was
floating - almost suspended over my windshield. I told my mother to
close her eyes - and it hit our hood - not the windshield. Within 2 to
3 minutes it was over.

Old massive trees were littered all over the streets and leaning on
second story bedrooms. I knew this was bad when I saw the Firemen in
their coats calling into homes making sure no one was hurt or smelled
gas.

Update, 9/17, 10:45 a.m.: Some more photographs here, plus details on the storm's path as well as the fatality on the Grand Central Parkway.
