Today, NOAA’s National Hurricane Center is able to issue five-day forecasts for hurricanes such as Katrina and Sandy thanks to better observations, atmospheric computer modeling and the use of satellites that are a forecaster’s “eye in the sky.” Hurricanes once surprised people, such as the Hurricane of 1938 that hit Long Island, New York, with no warning. As the quantity and quality of observations have improved, as computer modeling has become more detailed, as supercomputing has become more powerful, and as researchers study the mysteries of our weather and climate - so, too, have forecasts improved and will continue to improve. ![]()
