Wrong again, "my group" is not allowed to via the Ham 2 meter backbone used by our WFO for receiving ham storm reports. Not I or my group "wont" do this.
You are a bit mistaken here. Unless the NWS paid for the equipment, installation, and maintenance of the towers used for the weather net, they have no authority to regulate what is and isn't said over the airways. The NWS does not regulate the airways; the FCC does.
Now, if a user is interfering with operations, actions can be taken to punish said user, but this would be done under the purview of the FCC, not the NWS. I highly doubt the FCC would consider reporting an estimated distance during emergency operations as interference. Nor do I think they would consider that worthy of an investigation.
If what you state is true, and I have no reason to disbelieve you, and your WCM instructs you not to report estimated distances then one of two things must have occurred.
1. He, or the office, has received substantial misinformation from your group or others in the past and no longer wants to deal with said misinformation.
2. He, or the office, is willing to throw away valuable information in order to give the false impression of always being precise/accurate.
Lastly, I read up on this SULCOM organization, or whatever you want to call it, that keeps being referenced.
This is not official NWS policy. It has not been vetted by the NWS management, NOAA management, NOAA legal, NWS Employees Association (the Union). It has not been made available for public comment, nor has it had a public hearing. If your local NWS office wants to adhere to this policy, then so be it, but it cannot be construed as official NWS policy. I can also say that if your local NWS office misses a killer tornado that was observed by a storm spotter because people following this policy rejected a report that wasn't in the proper form (
click here for page saying reports in improper form will be rejected), you will have a fiasco on your hand that will involve congressional investigations. Don't believe me? Learn more about the story of the 21 April 1996 killer tornado that hit Fort Smith and Van Buren, AR. This event had an official NWS Service Assessment as well as congressional inquiries that lasted for years.
EDIT:
Tim, just want to clarify that this isn't a condemnation of you. If what you say is true, and I have no reason to believe otherwise, then this is a condemnation of the policy.
