Flood-Cast is a coastal flood early-warning app for Florida's Gulf coast — created after Hurricane Helene pushed record surge into homes along the coast, from the barrier islands to Tampa Bay. Instead of burying you in raw weather data, Flood-Cast watches the specific conditions that drive coastal flooding and tells you, in plain language, how worried to be right now. THE 4 FLOOD CONDITIONS Flood-Cast continuously checks the four factors that line up during the worst coastal floods: • Spring tide — a full or new moon, when tides run highest • King tide — a predicted high tide above the king-tide line • Hurricane on a parallel track — a storm running along the coast • Eye 40–75 miles offshore — close enough for the outer bands to push water inland As these stack up, your risk ring climbs from Minimal toward Flood Now — so you can watch the conditions building instead of being caught off guard. RECALIBRATED AGAINST HELENE Helene drove more than six feet of surge with its eye far offshore — a combination simple rules miss. Flood-Cast layers storm-surge, storm-size, and distance escalators on top of the base gate, so a large, distant, surge-driving storm still raises the alarm. WHAT YOU SEE • A friendly risk ring with a plain-language summary • The live 4-condition checklist, so you can watch conditions stack up • A tide curve with the king-tide line, highs, lows, and a "now" marker • A hurricane tracker showing the eye's distance, bearing, and the danger band • The moon drawn in its current phase • A 12-hour AI outlook that reads the trend and explains what's coming LIVE DATA • Tides from NOAA Tides & Currents (your nearest Florida station) • Active storms from the National Hurricane Center • Moon phase computed on your device — no network needed Flood-Cast won't cry wolf. A full Flood Now alert only fires when the conditions truly line up; the rest of the time it quietly shows you the coast is calm. Built for residents, renters, and anyone who loves the Gulf coast and wants a head start before the water rises. A 3-day free trial unlocks the full app. Continuous monitoring and alerts are available by subscription.

About

Tchoup

Features
Read full description

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.
