About

Is my street flooded? Tchoup answers that question for New Orleans — live, block by block. WHAT YOU SEE • Flood reports from neighbors: where water is standing right now, how deep (ankle, tire, bumper, up to the windows), confirmed by other people on the block. • Pump station status across the city, updated continuously. • Live rain radar. • River and canal gauges with flood stages. • Underpass danger zones — the low spots where cars drown. They glow red when flood-risk weather is active or flooding is reported nearby. • A shareable "roads to avoid right now" list for the family group chat. WHAT YOU CAN DO • Report flooding in two taps to warn your block. • Confirm or clear other reports so the map stays honest. • Save your home (privately) and get a push notification when a neighbor reports flooding within 1/3 mile. HOW IT STAYS TRUSTWORTHY • Sign-in is one tap (Apple) or a passwordless email link. • You can't confirm your own report. Reports expire after 3 hours unless someone confirms them, and disappear when neighbors say the water's gone. • No ads, no tracking, no data sales. Your home location is never shown to anyone. Turn around, don't drown. If there's water across the road, don't drive into it — check the map, find another way. Tchoup is a product of Edge Orbital, made in New Orleans.
