Critical Weather Day outlook update
Critical Weather Day CRITICAL WEATHER DAY STATUS...
NWS does not currently expect to declare a Critical Weather Day in the next three days — no unusual operational precautions are planned.
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.
CWD outlook CRITICAL WEATHER OUTLOOK...
Looking three days ahead, NWS has flagged Sunday (Critical...Tropical Cyclone). On flagged days NWS may hold off on scheduled system changes to keep its forecast systems stable.
