Floyd passed over Long Island and tracked up into the Connecticut Valley. Here in the mid-Hudson Valley, where I live, winds brought branches and power outages lasted up to a week for some people. The exact track for Irene is changing on a day-to-day basis - the movement and strength of a trough of low pressure will affect the storm and may move it further east (or not).
A little emergency preparedness (non-perishable food, water, gas for your car, batteries, etc.) would be prudent.
The National Hurricane Center is the place to go for up-to-date information on the storm.
