The storm is expected to cause widespread impacts, including flash flooding in urban areas like Boston. Strong winds, potentially reaching hurricane force, could topple trees and damage power lines, leading to outages. The risk of tree damage is heightened as many trees still have leaves, which can catch more wind. Additionally, moist soil from recent heavy rains increases the likelihood of uprooted trees. Coastal areas may face dangerous surf, rip currents, and beach erosion, particularly in eastern Long Island and along the Massachusetts coast.
