Critical Weather Day ...CRITICAL WEATHER DAY DECLARED...

A Critical Weather Day has been declared because of excessive Rainfall and Flooding ops across southeast.

A “Critical Weather Day” is an internal NWS operations posture. When one is declared, NWS postpones scheduled software, hardware and network changes at the affected offices so that nothing is disturbed while forecasters are working high-impact weather. Emergency changes still get made, but they need senior sign-off. It is a signal about how NWS is protecting its own systems — it is not a forecast or a warning, and it does not tell you anything about conditions where you live.

Affected offices: NWS Central Operations, National Centers, and Weather.
