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

ellipsis (SUMMARY...).

 

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
