Satellite sector moved
Satellite moves MDS STATUS...
Each GOES weather satellite has two “mesoscale sectors” — small, movable windows that the satellite photographs roughly every 60 seconds, far more often than its routine full-disk and continental scans. Forecasters aim them at whatever is most important that day. This section announces where they are being pointed and for how long.
GOES-West is pointing mesoscale sector 1 over the eastern Pacific, about 1015 mi E of Hilo, HI — to keep a close eye on a tropical system. That means this patch of sky gets a fresh satellite image about once a minute instead of every 5 to 10 minutes, so forecasters can watch storms develop almost in real time.

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.
