Rain-flood danger

When rain becomes a daily-life risk

Heavy or repeated rain can quickly fill low points, cut a road, overflow a drain or worsen a river flood. Danger depends on place, drainage, soils and people’s exposure.

Signal24h accumulation, current rain, saturated soil or local incident.
PlacesLow neighborhoods, wadis, markets, roads, fields and schools.
RiskRunoff, stagnant water, cut access, contamination.
DecisionAvoid, postpone, protect, inform.
Two main forms

What people can observe

Rapid runoff

Water flows over the surface, moves toward low points and can cut a street, causeway or market access.

Overflow or stagnation

Water accumulates in low neighborhoods, fields, ponds, wadis and poorly drained areas.

Why rain alone is not enough

A large accumulation is not always an official advisory

Rain is an important signal, but risk also depends on soils, rivers, roads, housing density, already reported incidents and local response capacity.

Observation

The rain layer shows where accumulation is high.

Analysis

The watch compares rain with exposed areas and other evidence.

Publication

A published flood advisory is shown separately with its level and action.

Useful actions

The right steps to remember

Do not enter cloudy or moving waterHoles, sharp objects, open drains and currents are not visible.
Postpone non-essential tripsEspecially toward low roads, distant markets, fields or areas without network coverage.
Protect drinking waterCover containers, keep dirty water away and avoid drinking contaminated water.
Use simple wordsPlace, danger, action, next update. A short message travels better.
