<p align="left">There is a new methodology for
|
|
including SPC severe
|
|
convective watches into the GFE's Hazards Weather Element. This
|
|
framework is part of the GFE's VTEC infrastructure. The methodology and
|
|
infrastructure were designed by Matt Davis(ITO/NWS ARX) and FSL
|
|
Developers. Below is an example of how this methodology works.<br>
