The threat of flash flooding is increasing across Guam as Super Typhoon Bavi moves closer to the island.
As of 9 p.m. Sunday, Bavi was about 160 miles east of Guam, moving west-northwest at 13 mph with maximum sustained winds of 165 mph.
The storm is expected to pass near Rota or through the Tinian Channel around 8 a.m. Monday. The worst conditions on Guam are expected between 8 a.m. and noon Monday.
Rainfall totals of 12 to 20 inches are possible during the storm’s passage, with flash flooding expected through early Tuesday morning. Excessive runoff could flood rivers, creeks, streams and other low-lying areas.
Strong tropical storm-force winds of 58 to 73 mph are expected across Guam. The northern half of the island could experience Category 1 typhoon-force winds, with maximum sustained winds of 60 to 80 mph and gusts up to 100 mph.
Power outages and fluctuations were already being reported Sunday evening. Guam Power Authority crews were continuing repairs as conditions allowed, but crews will stop working when conditions become unsafe.
Residents are being warned to stay away from downed power lines and damaged electrical equipment because they may still be energized.
The Guam Waterworks Authority said 98 wells were online as of 10 p.m. and that the water distribution system will not be shut off during the storm.
Some customers in Malojloj were experiencing a water outage after the local booster pump station lost power. Crews were working to restore power and water pressure.
Emergency shelters across the island have now reached more than 50 percent of their total capacity.
Astumbo Elementary School has reached maximum capacity, and residents seeking shelter there are being redirected to Maria A. Ulloa Elementary School.
Machananao Elementary School was at 85 percent capacity, while Maria A. Ulloa Elementary School was at 63 percent. Officials are urging anyone who still needs shelter to go as soon as possible as conditions continue to worsen.
