Western Pacific typhoon wind and rain map
The western Pacific is the most active region in the world for tropical cyclones, called typhoons there. They can form in any month, though most appear between July and November, over water warmer than about 26 degrees.
To spot one, look for curved bands of heavy rain spiralling into a compact centre. Then look at the wind: the streamlines should turn anticlockwise around that centre, with the fastest flow packed on one side, often the side facing the direction of travel. Switch to the Pressure layer to see the deep low at its core, well under 1000 hPa.
Typhoons usually move west or north-west along the southern edge of a subtropical high, then recurve towards Japan, Korea or China as they meet the westerlies. Press play on the timeline to see how the pattern shifts in the next 48 hours.
The model grid is 0.25 degrees, so this map gives the broad picture, not the exact intensity at the centre. Do not use it for safety decisions; follow the bulletins of national meteorological agencies for warnings, forecasts and the official names of storms.
