While there is some rain, the real power is in the wind. You can hear it whoosh past the windows. It's when that turns into a whistle that it gets a little scary, because the speed has increased, a lot, and the windows begin to rattle.
If you look out and down, you'll see wet, brown flying leaves. Even though you know the wind is shooting downtown, the leaves themselves are flying in all directions.
The cloud cover isn't that thick. If it weren't for the sound of the wind, it might almost be an ordinary rainy day - until you look more closely out the window and what rain there is being blown sideways along Amsterdam Avenue.
