The Signal
The equatorial Pacific sits at 29.02°C, the hottest value in our entire record, and Humboldt County, Nevada is burning downstream of it. Three fires run through Great Basin sagebrush this morning across Calico, McConnell and California Creek. Roughly 17,000 people live in that county, and the nearest structural engine is 40 minutes from some of them.
The Brief
The Pacific's 29.02°C reading is the highest in our record, and its fingerprints are on 998 fire detections across the West. Five named fires are active in Nevada, New Mexico and Oregon. Arizona is under flood watches through Monday night while its neighbors burn. Bundibugyo Ebola in the DRC has passed 3,626 confirmed cases with no licensed vaccine. And Great Sitkin sits at aviation ORANGE in the Aleutians.
By The Numbers
29.02°C
Equatorial Pacific, MJJ 2026 season
The 100th percentile of our monitoring window, meaning there is no warmer comparable reading in the record to reason from.
998
Fire detections, western US and Canada
Satellite fire pixels, not fires; each one is a thermal anomaly hot enough for orbit to notice from 700 kilometers up.
3,626
Confirmed Bundibugyo Ebola cases in the DRC
The count stood at 1,481 on July 3. That is a doubling inside a single month against a strain with no licensed vaccine.
20
FEMA declarations in 90 days, 18 of them flood
Federal disaster capacity is being spent almost entirely on water while the West's fuel dries out on a separate clock.
“Ocean-to-land latency is the most underreported causal chain in emergency management. It is also the most generous, because latency is just another word for warning time.”
Lead Story
Pacific sea surface temperatures reached 29.02°C for the May-June-July window, the highest reading in our entire monitoring record, and the consequence of that single number is burning tonight in Humboldt County, Nevada. NOAA's Climate Prediction Center calls the state Extreme El Niño. The ranchers north of Winnemucca just call it another bad August.Satellite fire detections across the western US and Canada stand at 998 this morning. Three of them sit in one Nevada county: Calico at 41.87°N, McConnell at 41.52°N, and California Creek over in Elko. MODIS and Suomi NPP shortwave infrared show the Calico scar clearly, a dark bruise spreading through cheatgrass that cured out weeks early. Add LAUGHLIN in Colfax County, New Mexico and MUSTANG in Malheur County, Oregon, and you have a fire geography that lines up almost exactly with where spring rain never arrived.Here is the part almost nobody reports. Ocean heat does not stay in the ocean. It redistributes into continental precipitation deficits over a period of months, which is why a Pacific temperature logged in early summer is the best available predictor of what your fuel moisture looks like in late August. The same signature is written across the Amazon, where 2,217 fire pixels are burning right now, and into a global fire radiative power total of 87,096 megawatts.Ocean-to-land latency is the most underreported causal chain in emergency management. It is also the most generous one, because latency is just another word for warning time.
World Coverage
Himalayan border corridor, Nepal and Tibet · flood
Flood and debris flows along the Nepal-Tibet frontier have pushed the missing count to roughly 3,000, with 41 Australians among them and a group still trapped in a tunnel. Bad weather is grounding rotary search assets. High-altitude flood response is the hardest logistics problem on Earth, and monsoon variability is exactly what a disrupted Pacific delivers.
Great Sitkin Island, Alaska · volcanic
The Alaska Volcano Observatory kept Great Sitkin at color code ORANGE and alert level WATCH as of Saturday evening. Nobody lives on the island. Everybody flies over it, because the great circle routes between North America and Asia thread this airspace, and an ash column here reroutes hundreds of flights before most passengers ever hear the volcano's name.
Eastern Democratic Republic of the Congo · health
WHO's August 28 Disease Outbreak News reports further confirmed cases and deaths in the DRC. The trajectory since July 3, from 1,481 to 3,626, is the steepest of this outbreak. Bundibugyo is not the Zaire strain, which means the licensed vaccine and monoclonals in the global stockpile were built for a different virus. Contact tracing is the whole defense.
Himarë, Vlorë County, Albania · earthquake
A magnitude 4.8 struck 13 km ENE of Himarë on Saturday, with no tsunami threat issued. Albania's coastal building stock still carries the memory of 2019, when a M6.4 killed 51 people in Durrës. A 4.8 does not damage well-built structures. It does tell you which unreinforced masonry along the Ionian coast is still standing on borrowed time.
Global, Earth-facing solar hemisphere · space
NOAA SWPC issued warning WARK05 for a K-index of 5 on Thursday and extended K-4 warnings through Saturday morning. Minor storming degrades GPS precision and high-frequency radio at exactly the latitudes where wildfire aviation operates. Air attack over the Great Basin runs on radio discipline, and space weather is the variable nobody puts on the incident action plan.
Surviva Spotlight
Powered by Real-Time Intelligence
When the Calico fire perimeter updates, Surviva does not tell you a fire is burning in Nevada. It tells you whether the nearest active perimeter to your saved location has moved toward you since the last check, and it does that using the same NASA thermal detections we cited above, at your coordinates rather than your county's. If you set a location near Orovada, the Monday Medford wind window shows up as a change in your risk state, not as a press release you have to go find. Your family SOS network gets a check-in prompt automatically when a watch upgrades within your radius, which matters most in exactly the places where cell coverage is a rumor and one person always has signal on the ridge. This is what it means to be prepared before the headline breaks.
The One Thing
Today's Essential Takeaway
If you take nothing else from today's briefing: somewhere north of Winnemucca this morning, a rancher is standing at a fence line watching the Calico smoke column lean, doing the same arithmetic her grandfather did. Which way is it running. How dry is the grass. How long to get the horses out. She is doing that math with almost none of what we have. No fuel moisture dashboard. No probability curve. And yet the ocean told us in June that her August would look like this, and nobody drove out to tell her.That gap between what is known and what reaches people is the whole reason this exists. Not the data. The delivery. The Pacific handed us three months of lead time and we spent it on nothing, and that is a choice, not a limitation. So here is your Sunday assignment, and it takes ten minutes: find the one person in your life who lives at the end of a long road, and make sure they know what you know. That is the last mile. You are it.

Mission Briefing
Check the current perimeter distance between your home and the nearest active fire using InciWeb (inciweb.wildfire.gov), not a news map, because news maps lag perimeter updates by 12 to 24 hours and the Calico and McConnell fires are both moving.
If you are in Siskiyou, Modoc or Klamath county, pack and stage your go-bag tonight rather than Monday morning, because the NWS Medford fire weather watch covers Monday afternoon through evening and staging under wind is a fundamentally worse experience.
Set your vehicle fuel above half a tank if you live west of the Rockies; rural evacuation routes in Nevada and eastern Oregon routinely exceed 60 miles between fuel stops.
Buy or locate N95 respirators, not surgical masks, before smoke arrives. Wildfire PM2.5 requires filtration, not droplet capture, and rural pharmacies sell out within a day of a plume.
Build a box-fan and MERV-13 filter clean air room for one interior room of your home; total cost is under $60 and it removes the majority of indoor fine particulate.
Arizona readers in Yavapai, Coconino, Navajo and Apache counties: do not drive washes through Monday midnight. The flood watch runs to September 1 at 00:00 MST and six inches of moving water moves a vehicle.
Save your county emergency management page to your phone home screen today, and confirm you are enrolled in local reverse-911. In Humboldt County, Nevada that enrollment is the difference between a call and no call.
Identify the one neighbor on your road who is elderly, disabled, or without a vehicle, and make sure you have their phone number in your contacts before Monday.
Refill any prescription sitting below a 14-day supply; smoke events and road closures both interrupt pharmacy access, and ASHP shortage data shows respiratory medications tighten first.
Download an offline map of your county to your phone. Sustained Kp-4 geomagnetic conditions degrade GPS precision, and cell coverage across the Great Basin is fictional in places.
Preparedness Guidance
Start with smoke, because smoke reaches more people than flame ever does. With 998 satellite fire detections across the western US and Canada and five named fires burning in Nevada, Oregon and New Mexico, the households most at risk this week are not the ones inside a perimeter. They are the ones 80 miles downwind in a valley with no air monitor. Buy N95 respirators now, not after the plume arrives. Build the box-fan filter unit described above for one interior room. And if someone in your household has asthma or COPD, treat a visible haze as a medical event, not a weather condition.
Now the opposite problem, because the same broken circulation pattern is dumping water on Arizona. Flood watches run across Yavapai, Coconino, Navajo and Apache counties through Monday at midnight, and on the Colorado Plateau the danger is rarely the main river. It is the wash you cross twice a day without thinking about it. Six inches of moving water moves a person; twelve moves most vehicles. If you draw water from a small rural system, keep 72 hours stored, because turbidity spikes take small treatment plants offline faster than large ones.
Here is the meta-lesson for a Sunday. Every warning you receive is a late warning. Red Flag, Flash Flood, evacuation order, they all arrive at the end of a chain that started months earlier in the ocean. You cannot change the arrival time of those messages, but you can change what state you are in when they land. Fuel above half a tank. Documents scanned. Respirators bought in August, not September. Preparedness is just the practice of using the lead time somebody else already earned for you.
The Phoenix Signal
Pattern recognition from the editorial desk
Something changed in how I read the data this year, and today crystallized it. I used to treat the ocean feeds as background, the slow stuff, context for the real alerts. That was wrong. A sea surface temperature is not context. It is the earliest warning we get about anything, and it arrives months before the sirens with a level of confidence the hourly products can only dream about. We have built an entire emergency architecture optimized for the last hour of a threat and almost nothing for the first season of it. The Pacific gave us June. We spent it. Let's spend the next one differently.

Coming Next
Siskiyou, Modoc and Klamath counties, OR/CA · next 24h
Watch for:The Fire Weather Watch runs Monday afternoon through evening. The threshold that matters is sustained wind above 25 mph paired with relative humidity under 15 percent.
Escalation signal:An upgrade from Watch to Red Flag Warning with a new ignition inside the Klamath Basin
Yavapai, Coconino, Navajo and Apache counties, Arizona · next 24h
Watch for:Flood watches run to September 1 at 00:00 MST. Watch the Little Colorado River Valley gauges and prior burn scars along the Mogollon Rim, which flash at a fraction of normal rainfall.
Escalation signal:A Flash Flood Emergency issued for any Navajo Nation chapter community
Aleutian Islands, Alaska · 24-48h
Watch for:The Alaska Volcano Observatory is holding ORANGE. Any sustained ash emission above 20,000 feet forces immediate North Pacific route changes.
Escalation signal:AVO raises the aviation color code to RED
Eastern Democratic Republic of the Congo · 3-7 days
Watch for:WHO updates roughly every two weeks. The number that matters is not total cases but the proportion arising outside known contact lists, which is the signal that tracing has lost the chain.
Escalation signal:A confirmed case in a new health zone or across the Uganda border
Global, high latitude · 24-48h
Watch for:SWPC has issued extended K-4 warnings three days running. A K-6 threshold would degrade HF radio over the exact airspace wildland aviation uses in the Pacific Northwest.
Escalation signal:A G2 or higher geomagnetic storm watch during an active fire wind event
Monday afternoon into Monday evening is the sharpest window this week. The NWS Medford Fire Weather Watch covers the Klamath Basin, Shasta Valley and Modoc County, and if it upgrades to a Red Flag Warning with sustained winds above 25 mph, I would put the probability of a new significant fire start along the Oregon-California line at 55 to 65 percent. Simultaneously, the Arizona flood watch runs to Sunday midnight into Monday, so the same 24 hours will produce both a flash flood rescue and a fire start somewhere in the Southwest.
What I will be watching overnight is Great Sitkin. An ORANGE aviation code that goes RED reroutes the North Pacific in a matter of hours, and almost nobody outside Anchorage sees it coming. Stay satisfyingly prepared. — The Surviva-List Editorial Team
Editor's Note
From the Editorial Desk
Sunday mornings are for the slow stories, and this is the slowest one we track. NOAA's Climate Prediction Center has the equatorial Pacific at 29.02°C for the May-July window, the 100th percentile of our monitoring record. That water is why Humboldt County is burning.Through Monday evening, watch the Fire Weather Watch NWS Medford issued for Siskiyou, Modoc and Klamath counties. That is the sharpest edge of a fire season the ocean priced in three months ago.The ocean is the only forecast that lets you prepare a season ahead instead of a day. Use the lead time.
