JIC Release No. 2 - Typhoon Watch in Effect for Marianas


JIC Release No. 2 - Typhoon Watch in Effect for Marianas

The National Weather Service (NWS) Guam Weather Forecast Office continues to monitor what is now Tropical Depression 02W, formerly known as Invest 97W.

A typhoon watch is now in effect for Guam, Rota, Tinian, and Saipan. A typhoon watch means that typhoon conditions are possible within the next 48 hours. As of 1 p.m., Tropical Depression 02W was located near 5.6 degrees north latitude and 149.0 degrees east longitude. This was about 610 miles south-southeast of Guam, moving west-northwest, with 30 mph winds. 

Latest guidance indicates tropical storm force winds of 34 to 63 knots are possible early Tuesday morning but there is the increasing likelihood TD 02W could pass through the Marianas as a typhoon. If TD 02W moves faster than expected, this could result in conditions deteriorating as early as Monday afternoon. 

Prepare Now
The community is advised to take the following preparedness actions 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 warranted;
