Tropical Disturbance Continues to Move Toward the Marianas

Tropical Disturbance Continues to Move Toward the Marianas

The National Weather Service (NWS) Guam Weather Forecast Office continue to monitor what is now a tropical disturbance, centered in Pohnpei State, moving slowly to the west-northwest.
At 5 p.m. last evening, the disturbance was just east of Lukunor in the Mortlocks and about 210 miles west-southwest of Pohnpei, 285 miles east-southeast of Chuuk, and 915 miles southeast of Guam, with strongest winds near and south of the center at between 24 and 34 mph.  
This disturbance is expected to make a passage very near or over Weno, Chuuk today.
For now, the tropical disturbance is expected to pass south of Guam over the weekend. However, for Guam and the Commonwealth of the Northern Mariana Islands (CNMI), considerable uncertainty remains as to when it will pass and with what intensity. It is important to keep a close watch on the forecasts over the next few hours as it heads west-northwest. More information will be provided once available.
high surf advisory and high risk of rip currents is in effect for Guam, Rota, Tinian, and Saipan through Sunday night. Hazardous surf of 8 to 10 feet is expected to build between today and Saturday. The risk of rip currents is high. Avoid venturing near reefs and beaches, especially those facing west. Large breaking waves can knock you down and cause serious injuries. If caught in a rip current, swim parallel to shore and back toward the beach when possible. Do not attempt to swim directly against a rip current. Strong rip currents will be life threatening.
Due to the uncertainty of exactly how close to Guam the disturbance will pass and the strength, it is advised to take basicprecautionary actions now. To prepare for any scenario, residents and visitors are advised to:

·      Stay up to date with the latest information. The storm track or intensity may change and advisories regarding flash flooding or dangerous seas may be issued. 
·      Locate or prepare your emergency preparedness kits for your household; stock up on non-perishable food items and water for your household, flashlights, first-aid kits, batteries, matches or lighters, portable stove, toiletries, etc. Visit for more information on what to include in your supplies list. 
·      Secure important documents such as birth certificates, tax papers, and insurance documents and keep copies in a water-proof bag. 
·      Clear loose debris around your yard and store any items that may become airborne with heavy winds, before inclement weather arrives.
·      Gas your vehicles and get fuel for your generators now while the weather is clear. 

Those living in areas prone to flooding should be prepared to take action:
·      Clear drainage areas and un-block clogged storm drains in your area to minimize the chance of flooding
·      Residents living near rivers and streams need to review plans for protecting properties
·      Once heavy rains occur, 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
·      If there is a chance of flash flooding, move immediately to higher ground
·      If floodwaters rise around your car but the water is not moving, abandon the car and move to higher ground. Do not leave the car and enter moving water.
·      Avoid camping, parking, or hiking along streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning.

The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) remind the community to practice caution while traveling in rainy conditions through the weekend and avoid the ocean until hazardous conditions subside. Take flood preparedness action now and avoid hiking or camping near flood prone areas.
