Short-range rain forecasts keep missing — commuters left guessing

Heavy rain is flagged for the next two or three hours and everyone is told to grab an umbrella, yet by lunchtime the urban core is bathed in sunshine — a no-show downpour that leaves office workers second-guessing every plan. Local commuters say short-range rainfall forecasts have been badly off the mark lately: sometimes rain is called and none falls, sometimes clear skies are promised and a sudden downpour hits, directly affecting what people wear, how they commute and how outdoor work is scheduled, with outdoor workers and hikers finding it hardest to react in time.

Objectively, Hong Kong's small land area and the mixing of land and sea air currents make localised showers extremely hard to pin down, and with hardware upgrades constrained, the forecast time window and rainfall range are stretched very wide, draining the warnings of any reference value. Many residents have switched to overseas weather apps or started reading radar charts themselves, signalling a real demand for reliable, location-specific real-time weather information.

Overall, this points to a clear gap between existing channels and actual needs when it comes to ultra-short-range, ground-level weather information.
