AnalysisNotable

No longer in force

Hazardous rocket launching operations will take place in two defined areas off the California coast during multiple alternate time windows between 28 October and 3 November 2026. Mariners should avoid the listed polygonal areas during the published UTC periods. The message is cancelled at 030848Z NOV 26.

Avoid the two polygonal areas during the published UTC time windows and navigate with caution outside them.

Background (general knowledge, not from the warning)

These hazard zones cover downrange areas used for rocket launches from the U.S. West Coast. Vandenberg Space Force Base (California) is the established polar-orbit launch site on the U.S. West Coast and commonly produces downrange hazard polygons over the Pacific; this message likely notifies mariners of launches or launch-related operations. The polygon shapes protect the expected debris or drop zones along the launch trajectory. Mariners operating in the region should monitor Notices to Mariners and maritime warnings for updates or changes.
