Crowdsourced flood reports so the next commuter doesn't get stuck.
The idea came from a real commute: sitting in an Uber during heavy rain, unable to find a route into work that wasn't blocked by flooding, with no reliable way to know which roads were actually passable.
GH Floods was built to solve exactly that problem — letting drivers and commuters flag flooded or blocked roads in real time, so the next person heading the same way can route around it instead of finding out the hard way.
What shipped:
230 people used GH Floods within its first 24 hours alone — a strong signal that this was a problem commuters wanted solved the moment a tool existed for it. Reports are confirmed or cleared by the community and expire automatically, so the map stays current rather than cluttered with old reports.
GH Floods is live right now — no install, no signup wall.
