Live wind, storm tracks and the No. 8 signal chance — computed by our own model. Made in Hong Kong, for the world.
JMA and NHC tracks, wind radii and the No. 8 chance — one page per active storm, with the particle wind field rendered live.
A global particle wind field on a sphere with a ten-day timeline; press any point to read temperature, pressure and gusts.
VHHH runway wind rose, METAR and TAF decoded line by line, weather at both ends of a flight, and how far the route runs from a storm.
Mangkhut and Hato replayed hour by hour against ten stations; why eyewalls replace and wind fields grow.
Computed from the storm's track, intensity, wind radii and its position relative to Hong Kong, in three-hour steps, and labelled as our estimate rather than an Observatory forecast. The night before a typhoon, you know how likely a day at home is.

The global wind field is redrawn frame by frame with a ten-day timeline; press and hold any point to read the local temperature, pressure and gusts.
Map →
METAR and TAF for origin and destination side by side, and the route's distance from any storm marked leg by leg — see both ends before you fly.

The four half-hour cells on the Today page are the Observatory's radar-based gridded rainfall, and why there is no minute-by-minute bar.

The gale radius on a storm page is the agency's figure; its threshold sits below a No. 8, and the circle is not really a circle.

Forty perturbed tracks, and a count of how many bring gale-force wind to Hong Kong's offshore stations.
