Weather Alert Significance List

According to the wunderground documentation, there is a link to "http://www.nws.noaa.gov/os/vtec/pdfs/VTEC_explanation6.pdf" for a list of alert significance levels ['W', 'A', 'Y', 'S', 'F', 'O', 'N'], however today we received a significance of 'L' in one of the alerts.

Does anyone have an updated list of significance levels?

Thanks.

What alert was it?  I can check into whether it was an error or a new code

Hey Tim,  this is the alert (without the message and epochs)

<type>SPE</type>
<description>Air Quality Alert</description>
<phenomena>AQ</phenomena>

And these are the locations that I'm aware of that contain them:

 The zip codes that currently show these alerts are 49503 and 40229.

Thanks for looking into it.
