Storrington sits at the foot of the South Downs in West Sussex, below the wooded scarp near Chanctonbury Ring, with the flat Weald stretching away to the north. Rain arriving up the Channel meets the Downs first, and the scarp above the village often takes the heaviest of a passing band. Pulling up a Storrington rain radar clears this up quickly, as hyperlocal radar shows the rain's real position rather than a general outlook.
Frontal rain reaches the south coast up the English Channel from the south-west, and the Isle of Wight, the Downs and the coastline split bands as they move east. Warm sea in autumn adds energy to showers, which can build quickly along the shore while inland areas stay dry. The South Downs scarp rises straight up behind Storrington, so a band coming off the Channel lifts and drops its heaviest rain on the ridge while the village at the foot of the slope gets what remains.
In Storrington, England, RainViewer's live map reflects Met Office radar scans as they come in, roughly every 5 minutes. The live map shows whether a shower has already crossed the Downs above Storrington or is still climbing the scarp from the coast.
Along or across the Channel, Atlantic depressions track through, and named storms bring heavy rain, strong winds and high seas. Effects show first on seafront roads, ferries and coastal paths, and saturated ground under heavy rain raises flood risk in low-lying areas. Autumn and winter fronts come up the Channel and pile against the Downs above Storrington, and the streams draining off the scarp can rise quickly after repeated rain.
Cold showers cross the Downs in spring, and walks up to Chanctonbury Ring are the plans most often cut short. Fronts weaken and cold showers cross the coast, sometimes with hail. Forecasts struggle because the showers are narrow and quick, and seafront events and spring outdoor plans are the most exposed.
Summer storms build over the Weald to the north on warm afternoons, and outdoor events in the village depend on the gaps between them. Sea-breeze storms form where warm land meets a cooler sea, and thunderstorms can also drift in from the continent. Beach days, festivals and air shows all depend on the cell track, since a storm can reach the seafront within minutes.
The climb from Storrington up onto the Downs towards Chanctonbury Ring is fully exposed once you leave the village. Watch the cell approach on the radar and decide whether to start the walk or wait.
The South Downs Way along the ridge above the village catches weather first, well before it reaches the streets below. Check the radar to see whether a band is still climbing the scarp.
Storrington's High Street shops have limited cover between them on a showery day. See whether the cell will pass before crossing to the next row.
The A283 through Storrington slows in heavy rain, and spray builds fast where the road runs close to the foot of the Downs. The radar shows whether now is the moment to leave or wait it out.
RainViewer shows UK precipitation using data from the Met Office, the national weather service, which runs a network of C-band dual-polarization weather radars. The Met Office network also feeds the European OPERA composite, and the RainViewer map refreshes with each new scan, about every 5 minutes. From Storrington the map also covers Pulborough, Worthing and Horsham.
The South Downs scarp rises directly above Storrington, so a band coming up the Channel can be dropping heavy rain on Chanctonbury Ring while the village at the foot of the slope is still dry. Walkers heading up watch the ridge rather than the village sky. RainViewer shows the shower climbing the scarp.
Yes, the A283 through Storrington slows in heavy rain, and standing water can build where the road runs close to the foot of the Downs. A glance at the radar before setting off shows what's ahead. RainViewer marks the cell's position, so it is clear whether it is still coming or already gone.
Storrington itself sits on the lower slopes and drains reasonably well, but streams running off the Downs scarp can rise quickly after heavy rain and affect the lowest lying lanes nearby. The village centre usually stays clear. The radar shows whether heavy rain is falling on the ridge above.
May to September is the best window to visit Storrington, with Chanctonbury Ring, the South Downs Way and the village centre at their best. Spring showers can still cross the Downs with little warning. Check the radar in the morning and plan the walk for the dry gap.
Chanctonbury Ring sits high on the scarp where an approaching band lifts and drops its heaviest rain, while Storrington's village centre at the foot of the slope can stay drier until that same band moves down off the ridge. A forecast covers both places with one number, while the radar map shows the rain crossing Chanctonbury Ring and missing the village centre.
The Storrington radar map updates about every 5 minutes, in line with the Met Office's own scan cycle, rather than on a fixed forecast schedule. Met Office C-band radar over the south coast measures precipitation across the Channel as well as the land, showing an approaching band before it reaches the shore. That hyperlocal pace is fast enough to catch a shower moving across town in real time.
Set a rain alert on Chanctonbury Ring or the village centre and RainViewer warns you before rain arrives. That lets you time a walk or a market visit. The 2-hour forecast in 5-minute slices shows the next gap, and saved locations track the South Downs Way and Worthing together.
A walk up to Chanctonbury Ring and a morning on the High Street both depend on a dry gap, and RainViewer shows the next one.
Rain in Storrington comes up the Channel in bands, and a gap between two bands is often short.
Your weather app says showers in Storrington this afternoon. RainViewer's live hyperlocal radar shows the cell still on the scarp above Chanctonbury Ring with the village dry, which decides whether the walk starts now.
