National Weather Service Greenville-Spartanburg SC Transitioning
to a New Format for the Area Forecast Discussion Beginning Jan 12
2026

Beginning at 1200 PM EST on Monday, January 12, 2026, the
National Weather Service Greenville-Spartanburg, SC Forecast
Office will transition to a Key Message format for the Area
Forecast Discussion (AFDGSP).

This strategic change aligns the Area Forecast Discussion (AFD)
with an impacts-first message philosophy, enabling our office to
streamline communication and reduce redundancy. This transition
moves away from a strictly chronological layout to focus
immediately on potential weather impacts and hazards. By
prioritizing Key Messages, we aim to enhance clarity and eliminate
duplication within the Area Forecast Discussion.

A side-by-side comparison of the old format andthe new format
templates can be found at: https://www.weather.gov/erh/newAFD
