Jangmi has moved past Japan and is now transitioning into an extratropical system east of Honshu, but the impacts it brought are still being felt, including heavy rain, flooding and landslide risks, travel disruption, and power outages in affected areas.
We followed this storm from its early organization over the Philippine Sea, through its intensification and turn toward Japan, reading it through every layer of the atmosphere.
Storms like this are exactly why we watch the sky the way we do: not to marvel at them, but to see them coming sooner, so the people in their path have more time.
Below is a glimpse into the data weโre collecting in pursuit of better early warnings: a high-frequency, four-dimensional view of storms like Jangmi, from the top of the atmosphere down to the surface.
Bringing the invisible atmosphere into color.
Something new is on the radar. Get ready for a different kind of drop.
Meet Tropical Storm Jangmi (locally: Domeng).
Organizing from a depression into a named storm over the Philippine Sea, east of the Philippines, captured in a full 3D volumetric scan from the https://t.co/t7pYNUHOtw constellation at 1404Z on 28 May 2026 with two additional scans from the Tomorrow Constellation produced within the next 65 min at 1409Z and 1509Z.
Traditional high-frequency satellites give us a flat picture from above. Our sounders give us the vertical structure, moisture columns, cyclonic deep convection that could later organize into an eyewall, the early signals of strengthening, at a first-of-its-kind cadence.
And the stakes are not abstract. Directly downstream are the Filipino farmers we already serve, part of a global network of growers using https://t.co/t7pYNUHOtw data to protect harvests and manage risk where weather intelligence has historically been hardest to come by. Better observation means better odds for the people whose livelihoods depend on what storms like this do next. Scale that worldwide and you're not just forecasting storms, you're catalyzing global agricultural yield.
We'll keep watching. Every overpass is another slice of a global dataset built for one goal: detecting the causality behind rapid intensification, anywhere on Earth, before it unfolds.
The atmosphere is three-dimensional and evolves in real-time. Finally, our global observations are too.
Weโve launched software.
Weโve launched satellites.
Next, we launch ______.
Wrong answers welcome.
Coming soon.
This is severe weather, seen from space:
Hours before storms hit the Gulf Coast yesterday, @tomorrowio_'s satellite constellation was already tracking the atmospheric conditions driving them.
The visualization attached shows warm, moisture-rich air near the surface sitting beneath colder, unstable air aloft: the ingredients for severe storms already in place long before they formed.
With global atmospheric revisit rates every 60 minutes, our constellation continuously feeds the AI models powering our Resilience Platformโข in real time.
This is a perspective only https://t.co/t7pYNUHOtw can deliver.

When a satellite loses communications, most teams start writing the obituary.
Sam Gagnard and the https://t.co/t7pYNUHOtw Space & Sensors team didn't.
In our latest Expert Forecast episode, Sam explains what kept the team pushing when comms with their payload went dark: the radiometer itself was still functional. The problem was isolated. That meant recovery was still possible, even if only partial.
But the bigger driver was the constellation. Every lesson learned from one satellite applies to all the others. Even if you can't fully recover a payload, understanding what went wrong is its own kind of win.
That's how you build space weather infrastructure that lasts.
Watch the full episode to hear Sam break it down: https://t.co/TOyNvk0s8z
Weather intelligence unicorn @tomorrowio_ expands Series F to $210 million with $35 million in new funding.
New capital to accelerate DeepSky satellite constellation and agentic AI development.
https://t.co/NA6wQguswy
Today, we're expanding our Series F with an additional $35M investment from @Pitango and their partner @HarelInsurance bringing the round to $210M.
This reflects continued conviction in https://t.co/t7pYNUImj4 as the #1 AI-native Resilience Platformโข that businesses, governments, and communities rely on to operate in an increasingly volatile world.
The capital will support continued investment across the full platform, including software, AI models, and our next-generation satellite infrastructure.
Thank you to @Pitango and @HarelInsurance for the continued partnership and to our customers and team for making this work possible!
What makes https://t.co/t7pYNUHOtw different as a place to do weather science? Max Green, one of our data scientists, puts it simply.
The data. We operate our own satellite constellation that measures how temperature and humidity actually vary through the atmosphere. That's not something most forecast teams have access to.
The pace. If a new strategy is emerging in academic or industry research, we're testing it fast. If it doesn't work, we move on. No months-long approval cycles.
For scientists used to slower-moving institutions, that combination changes what's possible.
Most people picture weather satellites as cameras in the sky. The https://t.co/t7pYNUHOtw sounder satellites work differently.
They use passive microwave radiometers to pick up natural emissions from the atmosphere across a range of frequencies. From those signals, scientists can reconstruct vertical profiles of temperature and moisture, essentially a cross-section of the atmosphere at any given location.
That's the data weather models have always needed more of. A constellation of satellites in low Earth orbit, each with a wide collection swath, delivers global coverage frequently enough to actually improve forecast accuracy.
Better predictions start with better data.
This is what closing that gap looks like.
If you want to hear more from our space team about the constellation and how we recovered from the S1 satellite loss, watch the full episode with Sam Gagnard here: https://t.co/ZF8NpsCHmb
Earlier this month, Super Typhoon Sinlaku formed, rapidly intensified to a Category 5, and made landfall on the Northern Mariana Islands, all within about a week.
https://t.co/t7pYNUHOtw's TMS constellation captured the full storm life cycle as it approached Guam.
This is what our satellite constellation captures, enabling consistent tracking of a storm from formation to landfall, including the moments of rapid intensification that matter most for early warning.
More revisits mean earlier signals when a storm is strengthening. More clarity on where impact is heading. More opportunity to act before it's too late.
That could mean rerouting flights, adjusting operations ahead of landfall, or avoiding unnecessary shutdowns when the risk doesn't materialize.
Better data changes outcomes.
We heard a couple of weather apps are down today... ๐๐
If you still need a weather update, consider the https://t.co/cD3wSxpjMA weather app, available on the App Store: https://t.co/oHkpxVntR1
Everyone is talking about agentic AI. ๐คย
Most platforms still give you a static map and a forecast.
Our Spring release is what agentic actually looks like in operations.
Weather intelligence that lives on the asset, in the cockpit, inside the agent, and across the alerts your teams already depend on.
What's new in this release:
Asset Insight Dashboard: Monitor flights, routes, vessels, and insured portfolios with the operational context your business actually runs on. The pin on the map just became a living asset.
3D Map and Pilot View. Render volumetric clouds, storm tops, AIRMETs, and SIGMETs at the altitudes they actually occur. For the first time, dispatch and the cockpit can share the same view of the sky.
https://t.co/t7pYNUHOtw MCP Server. Your agents and pilots can now pull our intelligence as a first-class input. No custom wrappers. No brittle glue code.
Smarter alerting at scale. Grouped alerts and location subscriptions take the noise and the admin overhead out of running alerting across many locations and teams.
This is what we mean by "agentic". Not a chatbot bolted onto a forecast. Real intelligence, in the moment, where the decision actually gets made.
Here's a sneakpeek of our MCP update.
Read the full release rundown ๐

AI is rewriting the rules of weather forecasting, and not in small ways.
The physical equations and legacy methods that defined the field for decades are giving way to a completely different way of operating.
Our science team is building it in real time, producing hyperlocal forecasts every 15 minutes and bringing that precision to parts of the world that have never had access to this kind of data.
Hear from the scientists doing this work!
Next week, we're hosting a webinar worth clearing your calendar for.
Beyond the Data Gaps: Continuous Global Sensing with TMS | Wednesday, April 29, 10โ11AM EST
For the first time, a satellite constellation is delivering a complete atmospheric picture refreshed every hour, anywhere on the planet. With 12 Microwave Sounders now in orbit, we've reached a 60-minute global revisit rate, and we want to show you what that actually looks like in real data.
Reserve your spot: https://t.co/3YejNKIUvO
We're collecting a massive amount of data, and the results speak for themselves.
The timelapse below represents roughly two days of observations (10 April โ 12 April 2026) from our constellation of microwave sounder satellites. This is channel 12 (204 GHz), showcasing its sensitivity to land, ocean, and water vapor.
The visualization builds over time: the oldest data sits at the bottom, updating as new observations arrive. At this time scale, you can watch weather systems move in near real time.
Look for Super Typhoon Sinlaku near Guam in the western Pacific (right side of the image), or the cold air pushing off the east coast of the US (top left).
Until now, visualizations like these were only possible at visible and infrared wavelengths from geostationary satellites โ neither of which can penetrate clouds.
We are now enabling a far more nuanced understanding of weather conditions on Earth. To put it in perspective: the https://t.co/t7pYNUHOtw Microwave Sounder (TMS) constellation collects approximately half as much data as all other microwave sounders on orbit today โ combined.
This is the caliber of data we're now capturing, and we're working to get it into the hands of people around the world.
From orbit to ground level, @tomorrowio_ is turning satellite data into real-time intelligence that moves the world more safely and efficiently.
