Friday morning: Tropical storm-force winds begin to affect the southern Jersey shore.
Friday afternoon: Conditions rapidly deteriorate in South Jersey while heavy winds and rain enter the New York metro area. (Those who hold tickets to Friday’s U.S. Open matches, consider yourself warned.)
Friday night: Residents will see the worst of the conditions as Hurricane Earl makes its closest approach. That means gusts up to 80mph on the Jersey Shore and Eastern Long Island, with gusts to 100mph at Montauk Point. The city could see gusts to up 40mph, higher in the top floors of Midtown skyscrapers.
