HEAVY RAIN AND GUSTY WINDS POSSIBLE LATE SATURDAY NIGHT THROUGH MONDAY... A tropical system, Invest 98W, continues to be monitored by the Joint Typhoon Warning Center (JTWC) and your National Weather Service Forecast Office in Guam. At this time, we expect this tropical disturbance to lift slowly north as it tracks roughly parallel to the Marianas, west of the coastal waters. Heavy rainfall will be the main concern with this disturbance, with the potential for 4 to 8 inches of rainfall, perhaps with locally higher amounts. Additionally, stronger winds on the northern and eastern flanks of the system may give Guam sustained winds of 25 to 35 mph, with gusts to 45 mph possible with any heavier shower or thunderstorm that develops. Much uncertainty exists amongst the various model guidance, and this system is still very early in its formation stage. Additional changes in the forecast track, intensity, and impacts to Guam. We urge the first responders and the public to continue to monitor the situation for later forecast updates.
