Tropical Depression Continues to Strengthen; Flash Flood Watch in Effect
At 5 p.m., the National Weather Service (NWS), Weather Forecast Office Guam, issued an updated advisory for Tropical Depression 10W. Guam remains in Condition of Readiness 4.
A tropical storm warning remains in effect for Guam and Rota, meaning damaging winds of 39 mph or more are expected tonight.
A tropical storm watch remains in effect for Tinian and Saipan, meaning damaging winds of 39 mph or more, are possible within 24 to 36 hours.
As of 4 p.m., Tropical Depression 10W was located 12.4 degrees north latitude and 146.1 east longitude, about 115 miles southeast of Guam and 190 miles south of Saipan, with maximum sustained winds of 35 mph. Forward motion will continue to increase overnight with a gradual turn toward the northwest.
The current forecast brings Tropical Depression 10W near southern Guam late Wednesday evening into early Thursday morning with damaging winds between 40 and 45 mph and gusts up to 50 mph in heavier showers.
A short term forecast has been issued for Guam and Guam coastal waters. A band of heavy rainfall associated with Tropical Depression 10W is moving through Guam coastal waters and will be moving across Guam from east to west between now and 6:30 p.m. Very heavy rains are expected, which could cause flooding of roadways and poor drainage areas, with wind gusts to 45 mph.
If heavy rain is encountered, slow down and use low beam headlights.
A flash flood watch is in effect for Guam, Rota, Tinian, and Saipan through Friday morning. Heavy rainfall is expected as the tropical depression passes through the Marianas overnight and on Thursday. Due to its slow motion, there is potential for excessive rainfall and flash flooding, especially across Guam and Rota. Rainfall of 4 to 6 inches is possible with locally higher amounts, especially for Guam and Rota.
Those living in areas prone to flooding should be prepared to take action should flooding develop. Clear any debris around drainage areas.
Residents who are concerned that their homes may not be able to withstand tropical storm conditions can call the GHS/OCD Watch Desk 478-0290 for coordination with village Mayor’s offices. The GHS/OCD 24/7 Watch Office will coordinate non-emergency individual requests for assistance from village mayors, government of Guam, military, private, and non-profit organizations.
As winds and rains increase through the evening, residents and visitors are advised to practice extreme caution if traveling on the roadways is necessary. Allow enough braking distance between cars to avoid any collisions and drive cautiously, being mindful of flooded roadways.
Mariners should make all necessary preparations to return to port, seek safe harbor and secure their craft. Dangerous rip currents are expected, along with 10 – 12 feet of open ocean and 8 – 10 feet of surf.
Store any items that may become airborne with heavy wind, including canopies and children’s outdoor toys.
Locate your emergency preparedness kits for your household.
Gas your vehicles and get fuel for your generators.
Secure outdoor pets in a safe location either indoors or inside the garage.
