Sandy Making Forecasting Changes


Nearly a year later since Super Storm Sandy, and some continue picking up the pieces. With torrential rainfall, high storm surges, and powerful winds, Sandy packed a punch along the Mid-Atlantic and North East Coasts. This unique storm reminded us that tropical systems in the Atlantic are not just confined to the Southeast or Gulf Coast. Many challenges and lessons were learned from forecasting Sandy.

Because of Sandy, the National Weather Service has broadened the definitions of a hurricane and tropical storm watches and warnings to allow watches and warnings to be issued or remain in effect after a storm becomes post tropical. As a result, our forecasters now have greater flexibility to communicate threats posed by transitioning tropical systems.

Sandy has also brought about technological changes. Newly upgraded super computers are now more than twice as fast as they were during Sandy. Forecast models are now more accurate with higher resolution.

The aftermath of Sandy just goes to show that sometimes we need to face disaster before we can experience changes for the better.
