Northwind

Weather-to-plan for outdoor crews

Know before the crew rolls.

Northwind reads the forecast the way a site foreman would, then gives your crew one line at 05:30: go, go with conditions, or hold. With the numbers that decided it.

The call

Hold 11:00 – 14:00

Gusts reach 34 km/h, 4 over the crane limit. Rain at 70% passes the 60% pour limit. Both ease by 14:00, then go.

01 · MethodThree steps, no black box

A forecast is a probability. A decision is a rule.

Northwind never asks you to interpret a chart. It reconciles the models, checks them against the limits your crew already works to, and shows its arithmetic.

Step 1 · Read

Reconcile four models into one hourly line

Gusts, rain probability, lightning distance and ground wetness, merged for your exact site and hour.

Step 2 · Apply your rules

Check every hour against your thresholds

Limits are yours, set once per crew type. Anything tripped is named, with its margin.

Step 3 · Decide

One call, sent before the crew leaves

The call, the hours it covers, and the rule behind it. Sent to the site lead and the crane supervisor.

02 · Try itSame rules, live

Move the weather. Watch the call change.

Pick a crew, then drag. Every crew type carries its own limits, because a tent, a crane and a drone do not mind the same wind.
