Part of the 2023 Pacific typhoon season

Typhoon Bolaven was an extremely powerful tropical cyclone that struck the Northern Mariana Islands in mid-October 2023. The fifteenth named storm of the 2023 Pacific typhoon season, Bolaven originated as a tropical depression on October 6 near the Federated States of Micronesia (FSM) and moved to the northwest. The system soon intensified into a tropical storm the following day. After a period of little to no organization, Bolaven strengthened into a typhoon as it passed through the Northern Mariana Islands on October 10. Extremely favorable conditions then led to Bolaven undergoing explosive intensification, quickly becoming a super typhoon shortly thereafter. The powerful cyclone then reached its peak intensity with a minimum central pressure of 905 mb (26.7 inHg) on October 11, eventually turning to the northeast in response to an approaching trough. Bolaven remained a super typhoon until October 13, at which point increasingly hostile conditions led to rapid weakening of the typhoon as it began extratropical transition, completing the process the following day. The remnants of Bolaven traversed the Northern Pacific Ocean until moving ashore in Canada on October 19, dissipating afterwards.

Bolaven impacted Micronesia and the Northern Mariana Islands, bringing scattered floods and downing trees as it passed through. After being absorbed by another weather system, its remnant energy brought wind and rain to areas in Alaska and British Columbia. No casualties were reported, but some minimal damage was reported.
