City-wide wet-bulb peaked at 26.3°C — 4.7°C below the level usually treated as extreme risk, so sweat still evaporates freely. Heat stress here is driven by air temperature rather than humidity, so shade and water matter more than shortened shifts.
FortyGuard env_params, sampled 2026-08-14, 74.4% mean relative humidity. Area-wide rather than per zone.
Slurred speech, trouble following simple instructions, or unsteady walking.
Sweating has stopped even though it is still hot. Treat this as an emergency.
Move the person to shade, cool them with water, and call for help immediately.
The risk score rates an area’s heat vulnerability from temperature and surroundings. It is a transparent prototype measure, not a medically validated threshold, and it does not tell you whether conditions are safe right now. General guidance only, not medical advice. If someone collapses, stops sweating, or cannot be roused, call emergency services immediately.
