Istanbul wakes to another deluge. Rain hammers the Bosphorus shoreline as rivers swell across Anatolia. But 6,000 miles away, a farmer in Bangladesh watches a satellite map pinpoint water creeping toward his village. In California's Central Valley, a levee manager refreshes her screen every 15 minutes. What connects them? Real-time flood intelligence that transforms raw weather data into survival decisions.

The Flood Risk layer on Pandita Data's Brain Dashboard does exactly that—visualizing live NOAA flood warnings, 7-day rainfall totals, and satellite-detected water extent across every populated basin on Earth. This is how modern flood preparedness works: data-driven, global, and personal.

THE FLOOD TAB

Open the Flood Risk layer on the Brain Dashboard and you see three critical intelligence streams converge:

⚠️
Live NOAA Warnings
National Weather Service flood alerts update every 6 hours, flagging Flash Flood Watches, Flood Warnings, and River Flood statements. Each alert includes specific river names, crests, and evacuation windows.
Latency: 6–30 min
📊
7-Day Rainfall Totals
Cumulative precipitation per city shows how much water has already fallen—critical for understanding saturation levels and urban flood susceptibility. Istanbul's current 7-day accumulation reveals why urban flooding is escalating.
Resolution: 4 km grid
🛰️
Copernicus SAR Flood Extent
Synthetic Aperture Radar from the Copernicus programme penetrates cloud cover and maps actual inundated areas in near real-time. Water reflects radar differently than land, creating a precise flood footprint independent of weather conditions.
Update: Every 6–12 days

UNDERSTANDING FLOOD RISK CIRCLES

The Brain Dashboard overlays concentric risk circles on each monitored basin and flood-prone city. These circles represent probabilistic zones where water-related hazards intensify based on historical flood frequency, terrain slope, urban drainage capacity, and current precipitation.

FLOOD RISK COLOR SCALE

Red: Active flood warning or 7-day rainfall >150 mm. Immediate danger. | Orange: High risk zone; 100–150 mm accumulated rain. Monitor hourly. | Yellow: Moderate accumulation (50–99 mm). Stay alert. | Green: Normal rainfall and flood conditions.

DATA SOURCES FOR FLOOD RISK

The Flood Risk layer synthesizes feeds from NOAA's National Weather Service, USGS stream gauges, the European Copernicus Sentinel-1 satellite constellation, and local hydrometeorological agencies. For Istanbul and other key cities, the Disaster Report (panditadata.com/disaster_report) offers deep-dive city-specific flood histories and seasonal vulnerability profiles.

The global picture: As of today, active flood alerts span the Danube Basin, Bangladesh delta, Indonesia, and the U.S. Gulf Coast—all visible on a single dashboard. One view. Many lives.
