Norfolk Is Radar Notes
| Location | Aerodrome, Norfolk Island |
|---|---|

| Typical Availability | 0000-0915; 1030-1515; 1630-2115; 2230-0000 |
The Norfolk Island radar has good coverage in most directions but trees to the north obstruct the radars view. Being a C Band radar, if there are large thunderstorms around, the radar may not be able to detect accurately the strength of other storms located behind the closest storms. This may also lead to the underestimation of the strength, at times, of very intense isolated storms. Heavy rain over the radar itself will reduce the reliability of the radar in all directions. There may be a tendency to observe areas of false echoes from the sea surface within approximately 50 kilometres of the radar. There is a blind spot of 4km radius centred on Norfolk Island Airport. Operational constraints may occasionally limit the availablility of data from this station.
About Future Radar
Future radar is a new drop-down option available on the Weatherzone radar, allowing you to see where precipitation may fall in the next 30 minutes, 1 hour or 2 hour timeframe. It is a prediction that uses past radar and satellite data to infer the movement and intensity of precipitation. This differs from observed radar which uses physical instrumentation to measure and render precipitation as it happens.
Future radar performs best with broad scale weather systems. However there are limitations in its performance when volatile convective systems develop and change within a short timeframe, as these scenarios provide local impacts that are difficult to predict in terms of speed, direction, intensity and shape.
To help visually distinguish between past timeframes and future timeframes, the radar animation will show predicted radar imagery at reduced opacity. You have the option to turn future radar on or off as it suits your needs.
