Hurricane Nolo: Where New Storm Exposure Met Existing Stress

Oʻahu and Hawaiʻi Island, Hawaiʻi
Event analysis period September 23–30, 2026
Coastal Hazard and Water-Quality Exposure Assessment

Examines how mapped and modeled coastal hazards coincide with infrastructure, impaired waters and community vulnerability across Oʻahu and Hawaiʻi Island during the September 23–30 analysis period. Mapunapuna, Keʻehi Lagoon and Honokōhau Harbor show concentrated exposure. This is not a report of observed flooding, surge, water-quality change or damage; the evidence snapshots cannot be timed against Nolo's passage.

All Five Boroughs
Compound Coastal and Tidal Flood Assessment

Examines eight public evidence layers across all five New York City boroughs. The July 18 analysis found the strongest combined signal in coastal and tidal conditions rather than river-stage exceedance. Modeled harbor disturbance is not observed inundation, and neighborhood impacts require confirmation through observed records.

ISSUE 003 Executive Summary

Executive Summary

On July 18, 2026, eight public-data layers were examined across all five New York City boroughs. The strongest event signal was coastal and tidal (not river-stage exceedance). Local rainfall was generally 0.1-0.5 inches, and NWS river forecast gauges remained below action stage.

TrueQi®, supported by Argus™, found the clearest convergence in NOAA STOFS-3D-Atlantic model output showing 1.9-2.5 meters of water-level disturbance across the Hudson, East, Harlem, and Arthur Kill waterways; multi-borough coastal exposure; low flash-flood thresholds in Brooklyn and Queens; and a later Above Normal streamflow signal on July 21.

Key Findings
Dominant Signal
1.9-2.5 meters · Harbor-wide model disturbance
STOFS-3D-Atlantic showed the same highest displayed tier across four major waterways
River-Stage Contrast
Below Action Stage · Steady trends
NYC-area NWS gauges did not show a conventional river-stage flood condition
Rainfall & Flash-Flood Context
0.1-0.5 inches locally · 1.0-1.5 in/hr FFG in Brooklyn and Queens
Rainfall was modest, but low urban thresholds leave little margin if a stronger cell shifts east
Assessment Status
Dominant coastal and tidal flood threat
Confidence is highest in the mechanism; exact local inundation requires observed confirmation

Why This Matters: Connected-Harbor Water Intelligence

Decision relevance came from convergence across an operational coastal model, static exposure layers, rainfall, streamflow, and river-stage status (not a single map). Below-action gauges and modest borough rainfall strengthen the coastal/tidal interpretation. Model output and scenarios are not observed inundation, so local impacts require confirmation.

Operational Assessment: Event Assessment · July 18, 2026

The integration of STOFS-3D-Atlantic harbor-wide disturbance and NWS below-action river gauges isolates the primary threat mechanism as coastal/tidal. Low urban flash-flood guidance in Brooklyn and Queens introduces a secondary compounding vulnerability. Actual inundation extent must be verified through observed records, as models only describe potential disturbance.

TrueQi® integrated eight evidence layers; Argus™ supported comparison. Directional convergence is strong on the coastal mechanism; exact local inundation requires observed confirmation.

Missouri Flood Event

Iron and Reynolds Counties, Missouri

ISSUE 002 Executive Summary

Executive Summary

From July 6-20, 2026, seven public-data layers were examined across Iron and Reynolds Counties, Missouri, including the Black River watershed and West Fork Black River drainage basin. The finalized Full Report classifies the event as a 1,000-year flood event (0.1% annual exceedance probability), while preserving material gaps in named-gauge readings, the Iron County Flood Hazard Outlook probability overlay, and actual inundation extent.

TrueQi®, supported by Argus™, found the strongest convergence in county-wide above-normal flow across every visible Iron County stream reach, 2.0-2.5-inch one-hour Flash Flood Guidance during the active event, mapped 100- and 500-year flood-hazard structure, no visible comparable event cluster in the 1950-2021 viewport, and a national Flood Hazard Outlook discussion dated July 20.

Key Findings
Network Status
County-wide above-normal flow
Every visible Iron County stream reach carried the same directional signal
Flash-Flood Resistance
2.0 to 2.5 inches · One-hour guidance
Model-derived threshold captured during active flooding; not a guarantee flooding will occur
Structural Context
Mapped 100- and 500-year hazard zones
Actual inundation was not mapped; the finding is recurrence-based context
Assessment Status
1,000-year flood event · 0.1% annual exceedance probability
Confidence is highest in directional convergence; exact magnitude and extent require confirmation

Why This Matters: Watershed-Scale Water Intelligence

Decision relevance came from convergence across connected stream reaches, current trigger guidance, mapped hazard structure, historical context, and national coordination (not a single gauge). Confidence is highest in the directional signal. Named-gauge stage and discharge, Flood Hazard Outlook polygons, and actual inundation were unavailable, so magnitude, timing, and extent require post-event confirmation.

Operational Assessment: Event Assessment · July 6-20, 2026

Every visible Iron County reach showed above-normal flow. One-hour Flash Flood Guidance was 2.0 to 2.5 inches during active flooding. FEMA mapped 100- and 500-year zones. The historical viewport showed no visible comparable cluster, and a July 20 national Flood Hazard Outlook discussion remained active. Missing gauge markers may reflect disruption or zoom/rendering; the cause was not determined.

TrueQi® integrated seven evidence layers; Argus™ supported comparison. Directional convergence is strong; magnitude, inundation extent, and missing gauges require confirmation.

ISSUE 001 Executive Summary

Executive Summary

In the early morning hours of July 5, 2026, four independent real-time environmental datasets converged on a single operational picture: the Guadalupe River at Kerrville, Texas had entered moderate flood stage at 13.74 feet, significantly above the established 11-foot flood threshold.

By synthesizing live stream gauge readings, streamflow anomaly data, Flash Flood Guidance thresholds, and Flood Hazard Outlook information, TrueQi® and Argus systems identified conditions where as little as 0.25 inches of rainfall within a single hour could trigger additional flash flooding across an already saturated watershed.

Key Findings
River Stage
13.74 ft · Moderate Flood Stage
25% above the 11-foot threshold at the Kerrville gauge
Critical Rainfall Threshold
< 0.25″ per hour may trigger additional flash flooding
Soils fully saturated. Even small rainfall events carry elevated risk.
Watershed Status
Exceptional hydrologic stress
Streamflows well above seasonal norms across Kerr County
Flash Flood Risk Level
Elevated · Ongoing · Additional rainfall expected
All four independent data sources aligned on the same operational picture

Why This Matters: Real-Time Water Intelligence

The Guadalupe River at Kerrville is a well-documented flash flood corridor. What this event demonstrates is the operational value of synthesizing multiple authoritative public data streams into a unified environmental picture. Stream gauge readings, streamflow anomalies, flash flood guidance thresholds, and flood outlook data are independently informative. Together, they are operationally decisive.

Operational Assessment: Current Conditions · July 2026

The Guadalupe River entered moderate flood stage at 13.74 feet (25% above the 11-foot threshold). Streamflows are well above seasonal norms. Soils are fully saturated across the watershed. Even sub-quarter-inch hourly rainfall accumulations carry meaningful flash flood potential until conditions normalize.

TrueQi® synthesized four independent data sources into a unified environmental picture. Argus identified the critical rainfall threshold: 0.25 inches per hour. The result: operational clarity in real time, not raw data.
