The U.S. Coast Guard Captain of the Port Forces Micronesia/Sector Guam has set Port Heavy Weather Condition (PHWC) WHISKEY for the Port of Saipan and the Port of Tinian, but both facilities remain open for commercial traffic and cargo operations, Port Technology International reported on 25 August 2026.
The PHWC WHISKEY designation was announced by the Coast Guard office identified in the report and applies to the two named ports. The report states the condition has been set while operations continue, signalling that the ports remain available to handle vessels and cargo movements.
Port Technology International’s item makes clear that Tropical Storm Saudel no longer poses a threat to the two ports named in the notice. The source states plainly that the storm no longer threatens the ports, and that ongoing operations reflect that assessment.
Commercial shipping and cargo handling are continuing at both locations, the report says, with neither port closed to traffic. The published update confirms that cargo operations have not been suspended as a consequence of the weather development covered in the notice.
Mariners transiting the area are advised to take the guidance contained in the notice into account. The published summary notes that mariners are advised to transit the area, reflecting the Coast Guard’s communication to those operating in and around the ports of Saipan and Tinian.
The update was carried on Port Technology International’s website on 25 August 2026 and summarises the Coast Guard’s position for commercial operators and mariners operating in the vicinity of the two ports. The report framed the setting of the PHWC WHISKEY and the continued opening of both ports as the central facts of the communication.
Operational status and ongoing movements
The central fact in the published notice is straightforward: both the Port of Saipan and the Port of Tinian remain open for commercial traffic and cargo operations despite the weather condition designation. The Coast Guard’s setting of PHWC WHISKEY has not resulted in a suspension of port operations according to the published account.
Guidance to mariners
Port Technology International’s item records that mariners are advised to transit the area, reflecting the formal communication issued alongside the condition setting for the two ports. The report identifies the advisory to mariners and the standing operational status of the ports as the key takeaways from the Coast Guard’s message.
