Cirié (Cirie) sits where the Stura di Lanzo river exits the Alps onto the Turin plain, at the gateway to the Valli di Lanzo, sharing the wider Turin region's roughly 982 mm of annual rainfall. A Cirie rain radar view matters because the town's fast Alpine river can rise sharply from rain that fell upstream in the valleys, even when Cirie itself sees only moderate local rain — hyperlocal radar is how you track that gap.
Orographic lift funnels moisture down from the Lanzo valleys onto the plain, adding to the Po Valley basin's usual W/SW Atlantic-front storms; Genoa Low systems drive the autumn peak here as elsewhere in Piedmont. The Stura di Lanzo's level at Cirié reflects rain and snowmelt collected far upstream, something a local point forecast for the town cannot capture on its own.
RainViewer shows precipitation building both over Cirie and up in the Lanzo valleys in real time, backed by the Protezione Civile's regional gialla-arancione-rossa alerts. A hyperlocal radar view lets residents see a storm sitting over the upper valleys before the Stura di Lanzo rises at Cirie.
Cirie follows the north Piedmont regime with an Alpine-valley overlay: a broad autumn maximum in October and November, summer afternoon thunderstorms fed by valley heating in the Lanzo valleys upstream, and winter snow at altitude with rain at Cirie's lower elevation. Regional fog affects the plain side of town on roughly 50 days a year.
Cirie's historic role as gateway to the Valli di Lanzo ties its calendar to the alpine hiking and tourism season upstream, which peaks through the warmer months and overlaps with the summer thunderstorm risk fed by valley heating.
The river can rise fast with heavy rain in the upper Lanzo valleys, even when Cirie sees only light local rain, so a hyperlocal radar view of the valleys upstream is the key early signal for residents downstream.
Valley-road closures during flash-flood events on the Stura di Lanzo can cut off traffic between Turin and the Val Grande, Val d'Ala and Val di Viù, and travelers check the radar before heading up to the valleys.
Cirie's historic identity as "città della scarpa" still shapes deliveries through the town center, and businesses plan around summer nubifragi disrupting routes.
A short drive southeast of Cirie, Caselle Airport traffic is exposed to hail and thunderstorm activity feeding down from the Lanzo valleys, worth checking before an airport run.
Cirie's road and rail links carry both alpine tourist traffic and Turin commuters, about 20 km south, and a live rain check before departure helps time trips around Genoa Low-driven autumn storms.
RainViewer draws radar data for Italy from the Dipartimento della Protezione Civile (Italian Civil Protection Department) national radar network, supplemented by regional radar systems from ARPA agencies including ARPA Veneto, ARPAE Emilia-Romagna, ARPA FVG, and ARPAL, updated every 5 minutes. Coverage spans the Italian mainland, Sicily, and Sardinia. The same map covers neighboring Turin, the Valli di Lanzo and Caselle Airport.
Check RainViewer's hyperlocal radar for a street-level view of rain over Cirie and the Valli di Lanzo, backed by the Protezione Civile's regional radar network. The map updates every 5 minutes, showing rain building upstream before it affects the Stura di Lanzo.
The river can rise quickly from heavy rain in the upper Lanzo valleys even when Cirie itself sees light rain, so watch the radar over the valleys upstream, where the rain is actually falling.
Yes — valley-road closures during flash-flood events can cut off the Val Grande, Val d'Ala and Val di Viù, so check the radar before heading into the alpine valleys.
No specific historical flood event is confirmed for Cirie itself, but flash-flood risk on the Stura di Lanzo is the town's defining local hazard, driven by heavy rain further upstream in the Lanzo valleys.
Late spring and early autumn suit alpine hiking upstream, though summer afternoon thunderstorms fed by valley heating are a regular risk through the warmer months.
Orographic lift forces moisture out of the air as it rises into the Lanzo valleys, so the mountains upstream can see heavy rain while Cirie on the plain below stays comparatively dry.
RainViewer's radar draws from the Protezione Civile's national network, refreshing every 5 minutes — frequent enough to track rain building in the Lanzo valleys before the Stura di Lanzo responds at Cirie.
Yes — set a rain alert for Cirie to get notified before a flash flood risk builds on the Stura di Lanzo or before a storm reaches the Valli di Lanzo gateway.
Heavy rain in the Lanzo valleys can raise the Stura di Lanzo at Cirie in hours, even when the town itself stays dry. A single-point forecast for Cirie misses that upstream signal entirely.
RainViewer gives you a 2-hour forecast in 5-minute slices, rain alerts before a storm reaches the Valli di Lanzo, direction arrows showing storms tracking down the Lanzo valleys or arriving W/SW off Atlantic fronts, 48 hours of radar history, and the ability to track multiple locations at once — Cirie, the Lanzo valleys, and Turin together. A static forecast tells you rain is possible today; live hyperlocal radar shows exactly where it's falling upstream right now.
