Port-call throughput deviation with a weather risk overlay - IMF PortWatch

For a set of the world's ports, how far the latest port-call count sits from each port's own recent baseline (a throughput DEVIATION, not a congestion, dwell or wait measurement - IMF PortWatch publishes none of those), reported ALONGSIDE a Weather-Disruption-Risk overlay and never blended into it. Pick the busiest ports (default), one country, or specific port ids. Directionally ambiguous and several days stale by construction; not for navigation or operational routing.
