The live radar above shows precipitation intensity across the UK, with colours ranging from light blue (drizzle) to red (heavy rain). For Norwich, the current display indicates a band of moderate rain moving east, clearing by late afternoon.
What do the radar colours mean?
Rain radar uk displays precipitation in real time. Light green or blue signifies light rain (0.5–2 mm/h), yellow is moderate (2–8 mm/h), orange and red indicate heavy downpours (8–30 mm/h). White or pink often shows hail or very intense convective rain. The scale is calibrated by the Met Office’s network of ground-based radars.
How far ahead can the radar predict rain?
The rain radar live feed updates every 5–15 minutes and can be used to estimate arrival times 1–3 hours ahead. For longer planning, see our 10 day weather forecast UK or check bbc weather for synoptic charts. The 3 hour rain radar loop is especially useful for timing outdoor activities in Norfolk.
Can rain radar show snow?
Yes – snow appears as a slightly different colour signature, often pale blue or white on the overlay. Many radar products now include a ‘precipitation type’ layer to distinguish rain, sleet and snow.
Why does rain radar sometimes show false echoes?
Ground clutter (buildings, hills) or interference from wind turbines can create speckled returns. These are usually filtered by the Met Office, but occasional artefacts appear near major structures.
Is rain radar available for Europe and worldwide?
The live radar above covers the UK only. For rain radar europe or rain radar world, we recommend using dedicated global services, though the coverage and update frequency vary.
