Rain and flood operational risk

Two hours of rain risk, for every site you operate

Live rainfall, drain water levels and the national nowcast, resolved down to the addresses your technicians actually drive to.

Per-site risk band, with the drivers shown

Every site carries a 0 to 100 score and a band from low to severe. Open one and the inputs are there: rainfall at the gauge nearest the address, the drain sensor in the same catchment, and the nowcast for the planning area, each with its share of the score.

Two-hour dispatch warnings

Before a visit is assigned, Squall checks the next two hours at the site and on the approach to it. Jobs that would land in heavy rain or a rising drain are flagged in the dispatch list, so a crew can be moved earlier in the day or held back rather than arriving at a flooded access road.

Alert rules with quiet hours

Set a threshold band per site or per group, choose email or WhatsApp, and give the rule quiet hours. Overnight rain only wakes someone when it crosses the band the rule names, and every firing is logged with the reading that triggered it and its delivery status.

A band you can defend in a call

Risk is recomputed as readings land, and each score keeps the inputs that produced it. When a site reads High at 15:40, the duty manager sees the gauge totals, the drain level against its alert threshold, and the forecast for that planning area.

The same three inputs are used for every site, so a score of 72 means the same thing on Jurong Island as it does in Bedok.

The data underneath

Refreshed through the day. Attribution in the footer.

Rainfall across Singapore: NEA; Gauge totals from the islandwide rain station network, matched to each site by distance and summed over the window that matters for drainage.
2-hour Weather Forecast: NEA; The national nowcast for the planning area a site sits in, so a dispatch decision looks at the same two hours the crew will be working in.
Water Level Sensors: PUB; Drain and canal water levels from PUB telemetry, with the sensor nearest each site tracked against its own alert level.
