The National Weather Service office in Tiyan, Guam, issued a Tropical Storm Warning at 9:21 PM ChST on October 2 for Tinian, Saipan, and the coastal waters surrounding both islands. A Tropical Storm Warning means sustained winds of 39 to 73 mph are expected within the next 36 hours, and preparations should be completed quickly.
The warning covers four areas: Tinian, Saipan, Tinian Coastal Waters, and Saipan Coastal Waters. Residents across both islands should expect strong winds, periods of heavy rain, and rough seas. Coastal waters will become dangerous, with choppy surf and hazardous conditions for any small craft. Flight operations at Saipan International Airport and ferry service between the islands could face delays or cancellations as conditions worsen.
What to Do Now
Secure loose items outdoors. Patio furniture, trash cans, tools, and anything else that could become airborne in 40+ mph winds should be brought inside or tied down tonight.
Stay off the water. Small boats should be secured in harbor, and swimming, diving, and fishing along coastal waters should be avoided until the warning is lifted.
Charge devices and stock basics. Tropical storms in the Marianas frequently cause localized power outages. Charge phones and power banks, keep flashlights handy, and have a few days of water and non-perishable food on hand.
Expect the worst conditions while the warning remains in effect, and monitor local radio and official updates for any changes in the storm’s track or intensity.
Data comes from the National Weather Service office in Tiyan, Guam (NOAA/NWS), which issues tropical cyclone warnings for the Commonwealth of the Northern Mariana Islands.
