JIC Release No. 2 - Typhoon Conditions Projected; Take Necessary Precautions through the Weekend

JIC Release No. 2 - Typhoon Conditions Projected; Take Necessary Precautions through the Weekend

The National Weather Service (NWS), Guam Weather Forecast Office continues to monitor a Tropical Depression that is expected to become a typhoon by the time it makes its closest point of approach to Guam.
Closest point of approach is currently expected to be late Tuesday evening, early Wednesday.
The storm currently is located at 12 degrees north latitude, 167.5 east degrees longitude, about 1530 miles east of Guam – that means there is enough time for the storm to exceed current projections.
Weather Update
The tropical depression is expected to continue moving west and strengthen. The current models forecast the system to impact Guam by Tuesday evening or earlyWednesday, becoming a possible Category 3 or Category 4 typhoon.
A Category 3 Typhoon is referred to as a “Strong Typhoon” with maximum sustained winds of 111-129 mph and peak gusts of 140-164 mph.
A Category 4 Typhoon is referred to as a “Very Strong Typhoon” with maximum sustained winds of 130-156 and peak gusts of 165-198 mph.
NWS advised this may be the worst typhoon to impact Guam since Typhoon Pongsana in 2002.
The problem posed by NWS is that the storm has enough time to significantly develop before reaching Guam.
These projections may change as the intensity and conditions have the ability to worsen.
Coordination Underway
The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) and personnel from the Government of Guam and military personnel that play a role in the GHS/OCD Emergency Operations Center, received a heavy weather brief from the NWS. Respective village mayors have also met with GHS/OCD and received the heavy weather brief by NWS.
Coordination is underway between GHS/OCD, Mayor’s Council of Guam (MCoG) and the Department of Public Works (DPW) to clear village drainage areas that pose a problem in heavy rains.
Shelter Operations

Discussions are underway to move to COR3 by Sunday. This can change depending on the forecast track.
Plans are in place to open respective Guam Department of Education (Guam DOE) emergency shelters and preparation is also underway for pregnant mothers at the Guam Memorial Hospital. More information will provided by Sunday.
