Flood Watch

Redondo Beach, WA

Day 1: 2025-09-04

CATEGORY 2

WHAT
No risk of flooding is expected on 09/04. The afternoon high tide will reach around 18.66 ft, but NOAA’s likelihood of flooding remains at 0.0%. Winds are relatively light, and barometric pressure around the peak tide (approximately 1007 hPa) is not sufficiently low to escalate flood concerns.

WHEN
Highest risk period corresponds to the afternoon high tide near 15:54 local time, though conditions are still not expected to reach flooding thresholds.

IMPACTS
No impactful coastal flooding is anticipated. Normal tidal fluctuations may result in slightly higher water levels along beaches, but property damage or dangerous inundation is not expected.

ADDITIONAL DETAILS...

Compared to historical flood events, today’s pressure of around 1007 hPa is higher than the very low values typically observed in notable floods (e.g., around or below 992 hPa). Moreover, the tide height of roughly 18–19 ft falls below the 20+ ft levels often seen in higher-category events. NOAA’s 0.0% flood likelihood further indicates no current flooding concern.


Day 2: 2025-09-05

CATEGORY 2

WHAT
Again, no risk of flooding is expected on 09/05. The peak tide is near 18.92 ft in the late afternoon, and while barometric pressure is somewhat lower (around 999–1000 hPa), it is still not low enough to pose a significant flood threat. NOAA continues to forecast a 0.0% likelihood of flooding.

WHEN
Highest tide occurs around mid to late afternoon (approximately 16:18 local time). Despite a moderate tide and slightly lower pressure, conditions should remain well below flooding thresholds.

IMPACTS
No flooding impacts are predicted for Day 2. Coastal areas will see typical tidal variations but are unlikely to experience high water encroachment or road closures.

ADDITIONAL DETAILS...

Historical comparisons illustrate that notable flood events typically involve a tide exceeding ~20 ft combined with significantly lower pressures or stronger onshore winds. While the pressure on 09/05 is below average, neither the tide heights nor NOAA’s flood projections suggest any imminent flood risk.


Day 3: 2025-09-06

CATEGORY 2

WHAT
For 09/06, no risk of flooding despite the highest tides of the three-day window, peaking around 19.16 ft at mid-afternoon. Barometric pressure near that time hovers around 999 hPa, which is not low enough to produce a significant flooding scenario. NOAA again reports a 0.0% flood likelihood.

WHEN
Highest tide occurs in mid to late afternoon, with no expected surge or extreme conditions. Winds remain moderate, further reducing the chance of coastal flooding.

IMPACTS
No substantial coastal inundation is anticipated. Any rises in water level along immediate shorelines should remain within normal tidal behavior, posing little to no hazard to public or private property.

ADDITIONAL DETAILS...

Although the combination of a sub-1000 hPa pressure reading and a 19+ ft tide might warrant attention under some circumstances, it remains well below the levels historically associated with flooding. Ongoing NOAA data also indicates minimal concern for this date.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.

CATEGORY KEY

Categories 1-2: No risk of flooding.
Category 3: Close to a flood event and worth monitoring.
Category 4: Flooding is likely however, it is uncertain if this will cause major property damage.
Category 5: Likely to flood and cause property damage.
Categories 6-7: Extremely high risk of flooding and property damage.
