Instead, the NWS should ask the National Research Council or some other independent organization to do an independent assessment of its performance along with that of Mayor Bloomberg and other emergency officials. We need a comprehensive overview of the strengths and weaknesses of the warning system and response.
The NWS service assessment (SA) program is badly broken. The Joplin tornado SA was a complete joke. It never mentions its own mis-location and misreporting of the tornado's location and direction of movement. The SA report issued in the wake of the April 27, 2011, tornadoes in the South omitted several crucial issues.
I'm a huge fan of the NWS (as anyone who has read Warnings: The True Story of How Science Tamed the Weather can attest), but I also believe we have to be scientifically honest in order to continue to improve as an applied science. The NWS is hardly disinterested in its own performance. A report on Sandy, at minimum, should examine:
- Its decision not to issue a hurricane warning as a hurricane was approaching the coast was, in my opinion, disastrous. That is just my opinion. We need objective facts.
- To what extent did this decision influence Mayor Bloomberg and others to delay evacuations and/or make the evacuations less extensive than they should have been?
- Did this decision contribute to the drownings on Staten Island and elsewhere when the hurricane's storm surge overtook the island and the coastline?
- What was Sandy's real intensity? At least three independent meteorologists have come to the conclusion it was category 2 before landfall. I believe they may be right. The NWS has a long history of "adjusting" hurricane intensities after the fact (Hurricane Andrew, that many of us believed was a Cat 5 at the time, wasn't named a Cat 5 by the NWS until the tenth anniversary of the storm). This does not inspire confidence we are getting the accurate story now.
- We have made relatively little progress in forecasting hurricane intensity. Is it time for a different approach to that problem?
So, NWS, stop your plans to investigate yourself. The magnitude of the issues raised by Sandy are too great to the Nation. It is time for an independent investigation.
