GUZ001-171315- /O.CON.PGUM.TY.W.4029.000000T0000Z-000000T0000Z/ Guam- 306 PM ChST Sat Oct 17 2026 ...TYPHOON WARNING REMAINS IN EFFECT... ...PRECAUTIONARY/PREPAREDNESS ACTIONS... Make the final preparations to protect life and property. Rush to completion the hardening of your home or business by closing shutters and bracing garage doors. If evacuating, leave as soon as possible. Guard against being stuck out on roadways when dangerous winds and heavy rains arrive. Again, do not stay in a metal roof or container home. Remember, pets are not allowed in most official shelters, so check ahead with your intended shelter. If staying in a home, turn the refrigerator to maximum cold and keep it closed. Turn off propane tanks and unplug small appliances. Fill the bathtub with water in case the tap water becomes unavailable after the storm. This is for cleaning and flushing purposes. Do not drink it. && ...WIND INFORMATION... 15 to 25 mph north winds the rest of today, are expected to increase significantly as Champi approaches, with north to northeast tropical storm-force winds of 50 to 70 mph with gusts to 100 mph developing quickly coming into tonight. Then, varying winds immediately during closest point of approach over Cocos Island in southern Guam, shifting rapidly to the southwest, with typhoon-force winds of 110 to 130 mph with gusts to 160 mph expected by sunrise Sunday. As Champi continues moving away to the west or west-northwest, winds will decrease back down to severe tropical storm-force before noon Sunday. Damaging winds are not expected to depart until at least Sunday night. Devastating damage will occur. Structural collapse of some non- concrete homes could cause severe injuries or death. Most metal roof homes are likely to be severely damaged. Some container homes will be destroyed or severely damaged, leaving them uninhabitable. Flying and falling debris will pose a significant threat to life, or even death, to those venturing outside. Signage, some fences and canopies will be destroyed. Island-wide power loss is likely to occur, potentially for days or weeks, as power lines and power plants sustain significant damage. These power outages are likely to turn off public utility water pumps, so water outages may develop across the island if power outages continue for days or weeks. Shutters MUST be used for non-typhoon-resistant windows, as they are likely to shatter and bring in destructive winds indoors, which could cause severe injuries or death to those exposed. If landfall occurs over southern Guam, those venturing outside are at risk of severe injury or DEATH from flying and falling debris. Do NOT risk your life! ...COASTAL INUNDATION AND SURF INFORMATION... Hazardous surf will continue to increase, with dangerously large breaking waves 30 to 35 feet likely by early Sunday along shores directly exposed to the center of the system, as Champi makes its closest approach. Significant coastal inundation upwards of 5 to 7 feet is expected, especially along eastern and southern exposures as Champi passes. If Champi crosses over Guam, significant wave run-up is expected to build in along west exposures, including rising waters within Apra Harbor. If Champi passes south of Guam, impacts to western coasts will be significantly lower. Do NOT venture out into the waters during passage of Typhoon Champi. Surf and rip currents WILL BE DEADLY. Most typhoon-related deaths occur in the waters or along the shores. Storm surge is likely to come in fast and wipe out any infrastructure at points of peak exposure. Getting trapped in the waves WILL be life-threatening. Do NOT risk your life! ...OTHER STORM EFFECTS... Torrential rain could dump 8 to 14 inches of rain over Guam over the duration of theevent, especially if the system makes landfall. Excessive runoff is expected to result in flash flooding of rivers, streams, and other low-lying and flood-prone locations. Flash flooding may occur in poor drainage and urban areas. Storm drains and ditches may become clogged with debris. Extensive street flooding and flooding of creeks and rivers is likely. $$ MPZ001-171315- /O.CON.PGUM.TY.W.4029.000000T0000Z-000000T0000Z/ Rota- 306 PM ChST Sat Oct 17 2026 ...TYPHOON WARNING REMAINS IN EFFECT... .PRECAUTIONARY/PREPAREDNESS ACTIONS... Take small loose objects indoors. Identify suitable shelter. Stock up a few days worth of food and water. If no concrete shelter is available look for a cave or something similar. Take action to protect food crops or other possessions as appropriate. && ...WIND INFORMATION... 20 to 25 mph north winds the rest of today, are expected to increase significantly as Champi approaches, with southeast tropical storm- force winds of of 40 to 50 mph with gusts to 70 mph developing quickly tonight. Then, winds will pivot to the east-southeast and increasing to 50 to 60 mph with gusts to 90 mph Sunday, with frequent typhoon gusts developing. As Champi continues moving away to the west or west-northwest, winds will decrease back down to borderline tropical storm-force conditions late Sunday. Moderate to significant damage to some metal roof homes is likely, especially those that have canopies, awnings, or carports. Poorly constructed homes are likely to sustain partial roof removal, with some wall damage. Flying and falling debris may pose a significant threat to life, or even death, to those venturing outside. Signage, some fences and canopies are likely to be severely damaged. Island- wide power outages are likely, potentially for days, as power lines and power plants sustain damage. These power outages are likely to turn of public utility water pumps, so water outages may develop across the islands if power outages continue for days. Shutters MUST be used for non-typhoon-resistant windows, as they may shatter and pose a life threatening risk to those both outside and inside during the passage of Champi. ...COASTAL INUNDATION AND SURF INFORMATION... Hazardous surf will continue to increase significantly, with dangerously large breaking waves upwards of 25 feet expected to develop along all shores of Rota Sunday. In addition, significant coastal inundation upwards of 3 to 4 feet is expected especially along eastern and southern exposures as Champi approaches. ...OTHER STORM EFFECTS... As Champi continues to intensify and eventually become a typhoon prior to moving across the Marianas, torrential rain could dump 5 to 8 inches of rain at Rota over the duration of the event. Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas. Storm drains and ditches may become clogged with debris. Extensive street flooding and flooding of creeks and rivers are possible. $$ MPZ002-003-171315- /O.CON.PGUM.TR.W.4029.000000T0000Z-000000T0000Z/ /O.CON.PGUM.TY.A.4029.000000T0000Z-000000T0000Z/ Tinian-Saipan- 306 PM ChST Sat Oct 17 2026 .PRECAUTIONARY/PREPAREDNESS ACTIONS...

Then, winds will pivot to the southeast and increasing to 40 to 50 mph with gusts to 70 mph Sunday. As Champi continues moving away to the west or west-northwest, damaging winds are expected to subside late Sunday. Minor damage to some metal roof homes is possible, especially those that have canopies, awnings, or carports. Flying and falling debris may cause injuries to those venturing outside. Signage and canopies may be damaged. Scattered to island-wide power outages are possible, as power lines sustain damage. Shutters MUST be used for non- typhoon-resistant windows, as they may shatter and pose a life threatening risk to those both outside and inside during the passage of Champi. ...COASTAL INUNDATION AND SURF INFORMATION... Hazardous surf is expected to continue to increase, with dangerously large breaking waves upwards of 20 feet expected to develop along eastern and southern shores of Tinian and Saipan Sunday. In addition, significant coastal inundation of 1 to 3 feet is expected as Champi makes its way across the Marianas. ...OTHER STORM EFFECTS... As Champi continues to intensify and eventually become a typhoon prior to moving across the Marianas, locally heavy showers could dump 3 to 5 inches of rain at Tinian and Saipan over the duration of the event, especially if outer rainbands form and train over Tinian and Saipan. Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas. Storm drains and ditches may become clogged with debris. Extensive street flooding and flooding of creeks and rivers are possible. $$ Montvila
