The National Weather Service Guam Weather Forecast Office continues to monitor Invest 97W, which has been upgraded to a Tropical Cyclone Formation Alert by the Joint Typhoon Warning Center to a rating of high, meaning tropical cyclone development is likely within the next 24 hours.

As of 7:30 a.m. on May 19, the system was located about 200 miles south-southeast of Satawal and about 610 miles south-southeast of Guam, near 5 degrees north latitude and 149 degrees east longitude. It is tracking westward around 6 mph.

Current forecast has 97W favoring a track toward the Marianas, with a passage very near or over some parts of Guam or the CNMI early next week. Through the weekend, clear weather is expected for the Marianas before inclement weather arrives as early as Monday and continuing through Wednesday, with heavy rainfalls possible.

High uncertainty remains for the exact forecast track and intensity of the system as it approaches the Marianas. For Guam, it is expected to approach between Monday and Wednesday, with a potential for tropical storm to low-end typhoon force impacts. There remains a possibility for damaging to destructive winds and heavy rains, with increasing potential for hazardous sea conditions.

The community is advised to take the following preparedness actions between now and this weekend:

  • Those living in flood-prone areas should take action; clear drainage areas and unblock storm drains to minimize flooding;
  • Clear loose debris around your yard and store any items, such as tents and canopies, that may become airborne with heavy winds, before inclement weather arrives;
  • Stay up to date with the latest information. The system track or intensity may change, and advisories may be issued;
  • Locate or prepare your emergency preparedness kits for your household;
  • Secure important documents such as birth certificates, tax papers, and insurance documents, and keep copies in a water-proof bag;
  • Gas your vehicles and get fuel for your generators;
  • Be prepared to take action if shutters are recommended in the coming days
