The National Weather Service (NWS) Guam Weather Forecast Office continues to monitor Invest 98W as it becomes better organized. 98W is now the subject of a Tropical Cyclone Formation Alert, indicating further strengthening into a tropical depression is likely within 24 hours. As it approaches and strengthens, heavy rainfall and flooding concerns will develop for the Marianas.
What to Expect
There is a high likelihood that 98W will pass through the Marianas as a tropical storm or weak typhoon, possibly around Tuesday night. The latest forecasts now show 6 to 10 inches of rainfall are likely, with locally higher amounts near 12 inches possible. Strong wind gusts to 40 mph are possible with heavier showers or thunderstorms that develop. Waves may increase into the 10-to-14-foot range as fresh to strong sustained winds potentially develop, with near gale force gusts possible.
Response Efforts Underway
Officials, Mayors, and Emergency Operations Center personnel are receiving updated weather briefs for their response planning efforts. The Guam Department of Public Works has pre-staged heavy equipment in flood-prone areas islandwide.
More than 200 FEMA personnel are currently deployed in Guam, with more resources in transit, preparing for the possible incoming severe weather. The FEMA distribution center in Guam is ready to support and provide commodities if needed to both Guam and the Commonwealth of the Northern Mariana Islands. FEMA staff are coordinating with the territory and commonwealth leadership to integrate respective leads and identify resources that may be needed for the upcoming storm.
