Know when conditions reach your operating limits.
Watch wind at the crane, lightning near the terminal and water conditions at the dock. Signal4D puts your ports, zones and thresholds on the same map as the weather and sea state, with vessel tracking along your routes.

The view your team works with.
Port of Muskegon, Michigan with a Small Craft Advisory, a crane wind limit expected to be exceeded in 8 hours, and lightning within 10 miles. Product screenshot · Example configuration.
What your team can monitor.
- Weather over the port — wind and gusts against your crane limits, fog and visibility, lightning, storms and hurricanes, and heat, ice and snow
- Water conditions at the dock — tides and water level, waves and swell, currents, live buoy readings, and tsunami alerts, right on the map next to your ports
- Alert rules for each berth and crane, built on thresholds your team sets — plus lightning alerts for any zone you draw
- Add your own sites, zones, and routes to the map, then set up alerts to reflect the operations you actually run
Coming soon: historical data for audit trails and before/after storm imagery.
Port authorities
See weather and water hazards across the whole port, and coordinate closures and restarts from one picture.
Terminal operators
Know when gusts will hit crane limits or fog will slow operations, and plan shifts and vessel moves around it.

Questions from maritime & ports teams.
- How do ports monitor weather and sea state?
- Ports monitor approaching weather and sea state against the specific berths, cranes, and waterfront infrastructure they operate. Signal4D fuses marine forecasts, sea state, wind, lightning, and government warnings with a model of the port itself, and alerts when conditions will exceed the operating limits of a terminal or a piece of equipment.
- Can Signal4D track vessels in real time?
- Yes. Signal4D ingests live vessel telemetry and tracks ships alongside the weather and sea-state conditions developing along their routes — so operators see which vessels, crews, and cargo are exposed, and when.
- What maritime weather hazards does Signal4D cover?
- Signal4D covers sea state, wind and gusts, tropical systems and storm tracks, lightning, fog and visibility, and government marine warnings — fused into one operating picture that spans open ocean, coastal waters, and the port. Satellite-based observations from partners like Spire extend coverage to open-ocean regions other networks miss.
