Localizing flood risk alerts for communities

National weather warnings are too coarse for neighborhoods that flood first, delaying evacuation.

Problem

Barangays need street-level guidance; generic alerts cause warning fatigue.

Agencies issue province-level advisories; local officials interpret and relay by radio or chat.

Late moves of people and assets; unnecessary panic elsewhere.

Models combining rainfall nowcasts, elevation, and historical inundation can prioritize hyperlocal alerts.

Data gaps in informal settlements; connectivity during storms.

Missed alerts or false alarms eroding trust.

Sirens and manual gauge watching.

Sparse gauges; sirens lack specificity.
