SUBJECT: Implementation of Improved Space Weather
Watch
Effective July 25, 2012
Effective
Wednesday, July 25, 2012, at 1600 Coordinated Universal
Time (UTC), the
NWS Space Weather Prediction Center (SWPC) in
Boulder,
Colorado, will modernize its geomagnetic storm watch
products.
These products will now be issued relative to the
highest expected geomagnetic storm category (NOAA
Scale) and will
be based on the 3-hour geomagnetic K-index
rather than the
24-hour
A-index. This change will
better align the SWPC
Geomagnetic Watch
products with its Geomagnetic Warning products
and NOAA Scale designations.
The following
SWPC products will be affected by this change:
AWIPS ID WMO Header
Current Product Name NOAA

or

SWXWATA99 WOXX23 KWNP WATCH: Geomagnetic

The AWIPS ID and

same; however, the product names will change:
