Although the center of Gustav remained well offshore, the difference in pressure between it and a high pressure area over the central United States caused strong winds in areas of New Jersey on September 11. Wind gusts ranged from 35–45 mph (55–70 km/h), with stronger winds reported near the coast.[11] A maximum wind gust of 60 mph (100 km/h) was reported at Keansburg.[11] The strong winds downed trees and power lines throughout the eastern half of the state, damaging homes and blocking streets.
