Hurricane Sandy is expected to make landfall hours earlier than previously expected, likely reaching the coast of southern New Jersey or central Delaware early this evening.

According to the National Weather Service, Sandy is racing toward the coast at 28 miles per hour (44 kilometers per hour). The storm is blowing with maximum sustained winds of 90 mph (150 kph). Landfall is now estimated at between 6 p.m. and 7 p.m. EDT, hours earlier than previous forecasts of midnight or so.

Already, coastal areas are feeling the effects of the storm. Along the coast of New Jersey, winds have been gusting more heavily all day, with one station in the barrier island community of Harvey Cedars recording a 69 mph (111 km) gust. In New York City, a crane atop a partially-constructed high-rise collapsed, forcing evacuations in nearby buildings. The National Weather Service has issued a high wind warning for New York City and its suburbs, forecasting sustained winds of 35 to 45 mph (56 to 72 kph) with gusts up to 80 mph (129 kph). 

Wind speed is measured with instruments called anemometers, which simply record passing airspeed and thus take into account the storm's overall movement and its internal winds.
