Above are the RASP forecasts generated for this region and day. Forecasts appear here bit by bit as they are generated. Check forecasts for a previous day to see which times can be expected to be available. If there are only some or no forecast times listed then either something has gone wrong, or no forecasts are ready yet. If so please check back in half an hour to an hour.
Each forecast image has a timestamp in the upper right corner, this timestamp shows at what time the forecast was generated, and how far in the future the forecast is from the actual observations it was based on. For example, the timestamp "[22hrFcst@0409z]" means the forecast was generated at 04:09 GMT, and the forecast is for 22 hours into the future from the time the actual observations were made. Note that the observations were not made at 04:09 GMT.
