Subject: Addition of SUMMARY Section to Storm Prediction
Center (SPC) Public Watch Notification Message (SEL)
Effective April 14, 2015
Effective Tuesday, April 14, 2015, at 1500 Coordinated Universal
Time (UTC), the SPC will add a new SUMMARY section to Public
Watch Notification Messages (AWIPS ID SEL#). This additional
section will be in the free text area following the bullet format
of the primary threat information statements. The section header
is a single line with the word SUMMARY followed by a three dot
The new SUMMARY section is a general 1-2 sentence statement of
the severe weather expected in and close to the watch area. This
new section facilitates consistent, forecaster-driven, concise
communication for public consumption. The SUMMARY is intended to
be useful for a variety of communication needs including web page
headlines, social media and multimedia briefings.
In addition, the technical meteorological discussion section
(DISCUSSION...) that follows the double ampersand (&&) at the
bottom of the product will no longer be included in the SEL.
The discussion section is primarily for meteorological professionals.
This information will be included in a Mesoscale Discussion (MD)
product issued immediately after the SEL if the forecaster
believes there is new information superseding the pre-watch MD.
This change will support nearly simultaneous transmission of the
SEL containing public preparedness information and the Watch
Outline Update (WOU) product, which contains a computer-friendly
description of the watch spatial and temporal information.
The SUMMARY section in an MD associated with the watch and issued
immediately after the SEL will be identical to the SUMMARY
section in the SEL.
There are no changes to format or content to the MD product.
An example of the SEL with the SUMMARY section and an associated
MD are online at
