Unlike a hurricane where people have lost everything, the need for unsolicited goods isn't as great in this case.
Unsolicited goods can be more of a burden than a help in many emergency situations.
The mayor of NY has been on television exclaiming that they have more volunteers than they can handle now. Medical doctors and nurses may be needed soon, but right now there are more doctors than patients. If you try to go help, you will be in the way and you will be hindering rescue and recovery efforts. This may change and we will let you know. We are keeping a database of people interested in helping.
