*Kindly refer to your local warnings & bulletins issued by your country’s official weather agency. This advisory is intended for additional information purposes only.
+ Forecast Outlook: CHOI-WAN is expected to begin turning to the NW within the next 12 to 24 hours and may reach its peak wind speed of 270 kph before starting to lose strength. The 2 to 5-day Long-Range Forecast shows the howler recurving Northward to NNE-ward, passing about 110 km to the west of Iwo To on early Friday morning Sep 18 and about 170 km to the west of Chichi Jima on late Friday afternoon. CHOI-WAN shall continue to weaken as it accelerate further to the NE across a slightly cooler Northwestern Pacific Ocean.
+ Effects: CHOI-WAN’s dangerous main core (eye & eyewall) remains over warm open seas…its inner bands no longer affecting Agrihan and Alamagan Islands…Outer bands still hovering across the rest of Northern Marianas – bringing rains and winds not in excess of 60 kph. Typhoon conditions w/ winds of more than 200 kph can be felt along the path of CHOI-WAN. 1-day rainfall accumulations of 50 up to 250 mm can be expected along CHOI-WAN’s rainbands…with isolated accumulations of up to 400 mm near the center of CHOI-WAN or along its Eyewall. Residents in low-lying areas & steep slopes must remain alert & seek evacuation for possible life-threatening flash floods, mudslides & landslides due to the anticipated heavy rains brought about by this system. Precautionary measures must be initiated if necessary. Possible coastal Storm Surge flooding of more than 18 feet above normal tide levels…accompanied by large and dangerous battering waves…is possible along the coastal areas of Northern Marianas. Catastrophic damage is likely on this type of storm surge.
