No longer in forceA tropical storm has forced closure of multiple ports in the Marianas. Apra Harbor (Guam), Rota Harbor, Tinian and Saipan are closed until further notice. No re-opening time is given.
Do not attempt to enter or use the listed ports; avoid the area and follow local authorities' instructions.
Background (general knowledge, not from the warning)
The Mariana Islands (including Guam, Rota, Tinian and Saipan) are vulnerable to tropical storms and typhoons, which frequently force port closures and suspension of maritime services. Port closures are issued to protect vessels, harbour infrastructure and port personnel from high winds, heavy seas and storm surge. Mariners should expect disrupted schedules, suspended pilotage and towing services, and follow local harbour master and emergency authority updates. Further notices will advise when ports reopen.
