JIC Release No. 3 - Tropical Storm Warning in effect for Guam and Rota; Residents encouraged to prepare

Hagåtña —  Various government agencies have begun to prepare for anticipated storm conditions with the approach of Tropical Storm Man-Yi.  

The Department of Public Works (DPW) is working to clear culverts to avoid flooding as much as possible. DPW also is pre-staging equipment today to allow for quicker response time following the storm.  The Department of Education is prepared to open shelters once COR 2 is announced — which is anticipated later this evening depending on the forecast track of the storm. The Guam Memorial Hospital is preparing to receive expectant mothers once COR 2 is announced. The Guam Power Authority (GPA) reports that emergency water well generators are being topped off with fuel to ensure water wells remain operational. GPA equipment is also being topped off and materials are on standby to be deployed if necessary.

Guam remains in Condition of Readiness (COR) 3 at this time. 

“Given the information we have right now, we are expecting tropical storm conditions here on Guam by tomorrow morning. And I know many of us are preparing for Thanksgiving Day but please take some time today to take care of things at home – bring loose items indoors, prepare your emergency kits and clear away anything that could impact your power service line,” Governor Calvo stated. “Should conditions become worse than we currently anticipate we must be as prepared as possible.” 

“Hazardous surf, rip currents, and flying debris are expected. If possible, remain out of the waters and remain indoors,” stated Office of Civil Defense Administrator Charles Esteves.

What is now Tropical Storm Man-Yi is expected to make its closest approach, about 160 miles southwest of Guam tomorrow around noon.

The onset of damaging winds of 39 mph or more for Guam is likely Thursday morning into the afternoon. At this time, maximum sustained winds predicted for Guam are 35 – 40 mph with gusts to 45 mph. Guam is not expecting to receive destructive winds or typhoon force winds at this time. Rainfall amounts of 3-5 inches are possible during its passage. Sea conditions will be hazardous Thursday with 10-13 foot surf expected. The worst sea conditions are expected on the southeast side. Coastal inundation is expected for Ipan, Talofofo, Inarajan, and possibly Pago Bay.

Possible impact for Guam is some downed limbs and vegetation, some affected power lines and moderate to strong life-threatening rip currents.

As of 1 p.m., Tropical Storm Man-Yi was located near Latitude 7.2 degrees North and Longitude 150.1 degrees East, about 565 miles southeast of Guam. It is moving west-northwest at 20 mph, with maximum sustained winds of 60 mph. This general motion is expected to continue with little change in forward speed through Thursday.

The community is reminded that any shift northward in the current track could bring stronger winds and heavier rains to Guam. It is important to take preventative measures as early as possible. 

Those planning outdoor activities for Thanksgiving are advised to make plans to move indoors.

Residents and visitors are advised to continue preparations for the possibility of damaging winds on Thursday afternoon and evening. To prepare for any scenario:
  • Stay up to date with the latest information. The storm track or intensity may change and advisories regarding dangerous seas may be issued. Changes in Conditions of Readiness may be issued.
  •  Locate or prepare your emergency preparedness kits for your household; stock up on non-perishable food items and water for your household, flashlights, first-aid kits, batteries, matches or lighters, portable stove, toiletries, etc. Visit https://www.ready.gov/build-a-kit for more information on what to include in your supplies list. 
  • Secure important documents such as birth certificates, tax papers, and insurance documents and keep copies in a water-proof bag. 
  • Clear loose debris and vegetation around your yard.
  • Safely secure or take down any items that may become airborne with heavy winds such as wooden signs, canopies, tarps or trampolines, before inclement weather arrives.
  • Gas your vehicles and get fuel for your generators now while the weather is clear.
  • Those living in areas prone to flooding should be prepared to take action; clear drainage areas and un-block clogged storm drains in your area now to minimize the chance of flooding.
  • Avoid camping, parking, or hiking along streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning.
