Guam is now in Condition of Readiness (COR) 2.
In the interest of public safety, and as a precautionary and proactive measure, Governor Eddie Baza Calvo has placed Guam in COR 2 as of 8 p.m.
In conference with Rear Admiral Shoshana Chatfield, commander, Joint Region Marianas, only the Government of Guam will be in COR 2. Military installations on the island will remain in COR 3.
The decision to move the Government of Guam into COR 2 is based on the criteria of the onset of 39 mph damaging winds threshold; versus military installations whose decision is based on the criteria of the onset of 54 mph threshold destructive winds. Our military partners remain ready to support the island.
Based on its current track, and National Weather Service modeling, Southern Guam can expect sustained tropical storm force winds of 39 mph beginning on or around 10 a.m.
By 12 p.m. most of Guam can expect sustained tropical storm force winds of 39 mph.
By late-afternoon, Tropical Storm Man-Yi should be moving westward and away from Guam, ending tropical storm force winds on the island.
COR 2 means damaging strength winds are possible within 24 hours. As of 5 p.m., Tropical Storm Man-Yi was located 7.74 degrees north latitude and 149.1 degrees east longitude, about 495 miles southeast of Guam. Man-Yi is moving west-northwest at 20 mph with maximum sustained winds of 60 mph.
Tropical Storm Man-Yi is expected to make its closest approach around noon on Thursday, about 179 miles southwest of Guam.
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 Merizo.
