Flood Watch

Redondo Beach, WA


Day 1: 2025-08-28

CATEGORY 2

WHAT
Tides will reach around 18.3 feet near 7:42 PM, but with a relatively high barometric pressure (~1009 hPa) and NOAA’s flood likelihood at 0%, no flooding is expected.

WHEN
Highest water level around early evening (approximately 6 PM–9 PM).

IMPACTS
No significant flood impacts are anticipated. Low-lying areas should remain unaffected.

ADDITIONAL DETAILS...

Despite the moderate-to-high tide level, the barometric pressure remains well above the historically low values (below ~992.8 hPa) typically associated with notable flood events. NOAA’s analysis for this date indicates a 0% flood likelihood, which aligns with historical comparisons showing that far lower barometric pressure is needed to elevate flood risk at these tide heights.


Day 2: 2025-08-29

CATEGORY 2

WHAT
Tides will peak near 8:12 PM around 17.8 feet under higher barometric pressure (~1012 hPa). Again, NOAA’s flood likelihood is 0%.

WHEN
Late afternoon into evening (approximately 6 PM–9 PM) will see the highest water levels.

IMPACTS
No foreseeable flood impacts to shoreline roads or property.

ADDITIONAL DETAILS...

Although the tide will be moderately high, the weather pattern, with higher atmospheric pressure and calm to moderate winds, does not suggest coastal flooding. This aligns with NOAA’s low flood likelihood guidance and well exceeds historical low-pressure triggers seen in previous flooding events.


Day 3: 2025-08-30

CATEGORY 2

WHAT
A high tide of around 17.3 feet near 8:48 PM is expected, with barometric pressure still above 1008 hPa and a 0% NOAA flood likelihood.

WHEN
Highest tide levels around mid-to-late evening (approximately 7 PM–9 PM).

IMPACTS
No appreciable flooding is expected, and impacts to low-lying roads or property are unlikely.

ADDITIONAL DETAILS...

Although water levels approach similar heights to some past Category 3 events, the barometric pressure is considerably higher and winds are lighter. Historical data shows low-pressure systems below ~992.8 hPa are a vital factor in driving flood events, which is not the case here. NOAA’s forecast corroborates minimal risk.


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
