Officials with the U.S. Forest Service say five 20-person saw crews are getting briefed in New Jersey before being assigned to specific locations in that state.
The saw crews have experience clearing downed trees and removing debris.
About 60 other firefighter personnel from the Southwest are being assigned to help local emergency response agencies in New York and Massachusetts.
Officials say the crews were told to be prepared for more cold, rainy weather.
Another storm moved into New York and New Jersey on Wednesday, and authorities said rain, wet snow and 60 mph gusts could set back the cleanup and topple trees wrenched loose by Sandy.
