By the time it travels to NYC it will probably be nothing more than a tropical storm. At most I expect it will probably just be a really wet day. Announcing everything will be closed two days before it arrives seems like overkill. It's already been downgraded since yesterday and it's not due to pound here until tomorrow.
Yah well I would rather hear the warnings in advance (yes, even the 24/7 repetition by cable shows) than not be prepared if the thing does come ashore like the one in 1938. People who remember that one would think that closing shops and offices ahead of time was a really good idea.
I'm an optimist by nature. But hurricane warnings and watches are issued for good reason. And I wouldn't feel like a jerk if it later came in at "only" tropical storm levels and I had left the area. I wouldn't care if the thing fizzled out totally. I'd be happy it fizzled out, happy for the island, for the metro area, all its residents including all the birds and critters too.
People in my extended family were on the south shore of LI for the 1938 storm and it was memorable enough for them to have passed on the advice to leave on a hurricane warning (never mind hurricane watch), and to leave way way way before the storm comes ashore. They actually moved upstate permanently a year or so after that hurricane.
Material things can be replaced (or remembered fondly), so the main thing is to save your life. If I lived on the south shore of Long Island, I'd take personal ID, drinking water, a few granola bars, some cash, cellphone, a crank radio and flashlight, couple credit cards, lock the place up and be on the road tonight.
I'd be heading north and west, aiming to get north of Albany and west of I-81, which is about as far west as severe rain goes for bad autumn storms on the east coast. If the storm is like the 1938 one, the sand from the barrier islands will be in the living rooms of south shore homes by the time Irene is done. Who would want to be there for that, really?
All that said, I hope the Fifth Avenue Apple Store doesn't get blasted to smithereens. As material things go, it's sooooo beautiful.
