[UPDATES BELOW] There are multiple reports of flooding across the city due to the storm surge from Hurricane Sandy that is now upon the city. There have been reports of people trapped and cars floating in the middle of the streets. We've also received reports that many subway lines throughout the city have been flooded as well. The city has now issued a warning to all New Yorkers to go indoors immediately, stay away from windows, and remain indoors until further notice. We'll keep updating this post with more photos and reports from various areas where the flooding is happening.

Here's a video of flooding in Stuy Town:
