See the storm’s journey before it happens.
Hurricane Onset is a tropical cyclone lifecycle intelligence platform that measures conditions, system evolution, and potential impact corridors from disturbance through dissipation.
Live System Intelligence
Real-time environmental conditions, kinematic wind fields, and evolution across the complete lifecycle.
Onset Journey™
Track each system from pre-genesis disturbance to dissipation with a persistent, measurement-based identity.
Impact Intelligence
Connect measured storm corridors directly to geolocated infrastructure, power grids, and population exposure.
Most systems become operationally important before they become operationally obvious.
Traditional guidance is exceptionally good at describing and forecasting organized systems. The operational gap begins earlier — when conditions are aligning, signals are fragmented, and decisions may already need to start.
- Less lead time
- Fewer options
- Higher operational exposure
Too Late
The clock is already running.
By the time a system is officially classified, key preparation windows have often already shrunk.
DISTURBANCE DETECTEDToo Fragmented
The picture is scattered.
Environmental data, model guidance, observations, and asset exposure live in separate tools, forcing teams to connect the dots by hand.
Too Opaque
The answer arrives without the mechanism.
Many platforms provide outputs without explaining the physical drivers, constraints, or observation quality behind them.
Too Reactive
Action comes after the signal is obvious.
Crews, assets, and capital are often repositioned later than they could be, increasing risk and cost.
Hurricane Onset moves the decision point earlier.
By unifying environmental conditions, system lifecycle, and real-world impact intelligence, Hurricane Onset helps organizations see what's developing, why it matters, and what may be at risk — sooner.
SEE HOW IT WORKS
FROM EARLY SIGNALSTO REAL-WORLD IMPACT
Follow the whole lifecycle —
not just the next forecast point.
Onset Journey™ maintains one continuous identity for a system from early disturbance through peak, regression, and dissipation. Click any lifecycle station below to view measured telemetry.
Inner core eyewall formation. Sustained winds 64–82 kt.
For a live storm, the engine times this transition from its own run; see the Live view.

From disturbance to hurricane —
the same system, one continuous story.
Hurricane Onset maintains a single, consistent system identity (MW-2026-EP-W013)
across all official classification milestones. When NHC re-labels an Invest to a Depression, or a Depression
to a Named Storm, our continuity engine preserves the complete developmental ancestry.
One platform. Four operational views.
Hurricane Onset helps teams move from early signal to operational context — unifying real-time data, environmental intelligence, scenario analysis, and consequence insights in a single, decision-ready platform.
Active Systems & Corridors
Monitor active systems in real time with data-driven track intelligence, intensity forecasts, and the complete Journey™ timeline from emergence to dissipation.
- Real-time multi-basin system tracking
- Onset Journey™ timeline with NOW/NEXT transitions
- High-confidence forward corridor envelopes
- Official NHC & AI consensus overlays
Basin Environmental Readiness
Understand the environmental conditions that fuel or inhibit development across every basin before systems emerge into official advisories.
- Sea surface temperature & ocean heat content (OHC)
- Vertical wind shear windows & steering currents
- Triangulation probes across genesis corridors
- Observation coverage & blind spot transparency
Scenario Studio Modeling
Explore how changes in environmental conditions influence storm evolution, corridor trajectories, and landfall timing with interactive sensitivity testing.
- Adjust wind shear, ocean temperature, and moisture
- Compare multiple operational outcomes side-by-side
- Evaluate lifecycle ceiling sensitivity
- Test operational what-if scenarios for contingency plans
Exposure & Consequence Layer
Turn forecast intelligence into real-world insight with exposure analytics for population, property portfolios, and critical infrastructure across the storm corridor.
- Population and residential asset exposure
- Critical infrastructure risk (ports, grid, hospitals)
- Timing of physical stress onset (T+24h to T+72h)
- Custom region, portfolio, and asset boundary reporting
A different way to understand tropical cyclone evolution.
Hurricane Onset measures the environment, the system, and the lifecycle progression — not just a current track. We connect the dots from early signals to real-world impact, giving you a fuller, earlier, and more actionable picture.
A snapshot of where the storm is now.
Hurricane OnsetA complete, intelligent view of the journey.
Measurement-driven
Ingests and analyzes real environmental, structural, and observational data — not just model output.
Lifecycle-first
Tracks the full journey from disturbance to dissipation, with clear lifecycle states and transitions.
Persistent storm identity
Follows each system as a unique entity, maintaining continuity even through structural changes.
Built for decision-makers
Turns complex data into clear, actionable intelligence for real-world planning and response.
Built for decisions that
cannot wait for landfall.
Hurricane Onset helps teams understand what the measured storm corridor intersects, when exposure begins, and what infrastructure may be under stress — so you can act earlier and reduce operational risk.
Earlier insight. Smarter exposure management.
- Quantify property & portfolio exposure days before landfall
- Inform pre-event binding moratoriums and parametric triggers
- Reconcile catastrophe models with live physical telemetry
Keep people, power, and fuel ahead of the storm.
- Identify transmission line & substation exposure windows
- Pre-stage mutual assistance crews with 48h lead-time
- Reduce grid downtime and community outage duration
Resilient operations for essential lifelines.
- Assess operational vulnerability for ports and airports
- Safeguard hospital backup power and water treatment
- Strengthen interagency emergency coordination
Deeper context. Greater scientific confidence.
- Independent lifecycle layer alongside official advisories
- Historical analog re-analyses and scenario stress testing
- Crisp, auditable risk telemetry for executive leadership

Every prediction should leave a record.
Hurricane Onset preserves timestamped, cryptographically hashed measurement logs so lifecycle transitions can be compared against what actually occurred. We want the record to show exactly where the platform performs — and where observational gaps exist.

Built to understand the storm before the market fully sees it.
“What if the weather we understand today could be understood far earlier — before it ever arrives? Finding what is truly novel almost always means thinking outside the domain you started in. Hurricane Onset, and the Onset family of products, was built to merge separate worlds of understanding into the most advanced pre-intelligence systems in the world.”
Frequently asked questions
about Hurricane Onset.
Key facts regarding platform methodology, meteorological boundaries, and partner participation.
Hurricane Onset is a tropical cyclone lifecycle intelligence platform that measures environmental conditions, storm progression, and potential impact from early disturbance through dissipation. Rather than offering black-box probability scores, it continuously measures physical storm states, reachability windows, and environmental constraints.
