GOES-17 “Red” Visible (0.64 µm) images of the storm are shown below — the Mean Sea Level Pressure anomaly was 4-5 sigma below the climatological mean as the rapidly-deepening midlatitude cyclone made landfall. Similarly, 925 hPa wind speed anomaly was 3-5 sigma above the climatological mean. The system had transitioned to a warm seclusion phase by 00 UTC, as seen in a comparison of Visible and Water Vapor images at that time.

The OR/CA storm peaked pressure-wise with a central pressure of 970 hPa/28.64″ at 7 pm PST before slowly weakening. Here are its impacts thus far: pic.twitter.com/U4uHH0CBVW
