JIC Release No. 3 - Government and School Closures; Flight Cancellations

The Government of Guam will be closed on Tuesday, October 8, 2019, as Super Typhoon Hagibis continues toward the Marianas. The Government of Guam, Guam Department of Education schools, Guam Community College, and University of Guam will remain closed until Condition of Readiness (COR) 4 is announced. DODEA and Catholic schools will also be closed on Tuesday.

The National Weather Service (NWS), Guam Weather Forecast Office continues to monitor what is now Super Typhoon Hagibis. As of 4 p.m., Hagibis was located 15.5 degrees north latitude and 148.2 degrees east longitude, about 165 miles east of Saipan and 270 miles east-northeast of Guam. Super Typhoon Hagibis is moving west-northwest at 15 mph with maximum sustained winds of 150 mph.

Guam can expect damaging winds of 39 mph or more by early Tuesday morning. The maximum winds expected for northern Guam are between 40-50 mph. The maximum winds for southern Guam are 30-40 mph. At this time, destructive winds of 58 mph or more and typhoon force winds of 75 mph or more are not expected for Guam. 

Strong thunderstorms are now affecting western Guam coastal waters. Strong thunderstorms capable of producing wind gusts up to 45 knots, torrential downpours, and frequent lightning are expected. Mariners can expect gusty winds up to 45 knots, locally higher waves, frequent lightning strikes, and visibility of less than a half mile due to torrential rains. Boaters should seek safe harbor immediately. 

A typhoon warning remains in effect for Saipan, Tinian, Alamagan, and Pagan Islands, meaning typhoon conditions, including destructive winds of 74 mph or more, are expected later this evening. Damaging winds of 39 mph or more are expected soon. 

A tropical storm warning remains in effect for Guam, Rota, and Agrihan islands, meaning tropical storm conditions, including damaging winds of 39 to 73 mph are expected tonight.

A flash flood watch is in effect for Guam through Tuesday afternoon, meaning conditions may develop that lead to flash flooding. Frequent locally heavy downpours can cause streams to overflow their banks and low-lying areas to flood quickly. There is potential for 3 to 5 inches of rain across Guam with locally heavier amounts. 

The community is reminded to practice extreme caution if traveling in rainy conditions: 

  • Turn Around, Don’t Drown. Immediately move to higher ground if flash flooding occurs. Water levels can rise rapidly and sweep people away. Avoid walking or driving through flood waters. Just 6 inches of moving water can knock you down, and 2 feet of water can sweep your vehicle away
  • Stay away from storm drains, culverts, creeks, and streams. 
  • If floodwaters rise around your car but the water is not moving, abandon the car and move to higher ground. If the water is moving, do not leave the car.
  • Avoid camping, parking, or hiking along streams, rivers, and creeks. These areas can flood quickly and with little warning.
