The above images show 3-dimensional view of rain, in various shades of grey, as detected by Hong Kong Observatory's radar. Radar images at half-hourly intervals for the past 3 hours are normally displayed.
A weather radar may occasionally pick up signals from sources other than rain and clouds, such as reflection from ground, hills and sea. These signals may show up on the radar images. Please exercise care when interpreting the images.
