Flood Watch

Redondo Beach, WA

Day 1: 2025-08-31

CATEGORY 2

WHAT
No risk of coastal flooding is expected for day 1. Tide levels are forecast to peak near the mid- to upper 16-ft range, which is below thresholds typically associated with flood concerns in this area. Barometric pressure readings remain above 1000 hPa, indicating no significant low-pressure system is present.

WHEN
Higher tide levels will occur near midday, but are not expected to cause flooding.

IMPACTS
No flooding impacts are anticipated in low-lying areas. Normal beach and shoreline conditions are expected, and no significant property damage is likely.

ADDITIONAL DETAILS...

– Winds remain moderate and generally from the north, not conducive to onshore water piling.
– Barometric pressure readings (1001–1004 hPa) are well above the historical low-pressure storm thresholds (~992 hPa).
– NOAA’s Flood Likelihood data is not provided specifically for 08/31, but no notable risk factors are observed.
– Compared with past Category 3 events at similar tide heights (e.g., 17.46 ft on 12/27/2023), pressure and NOAA indicators suggest minimal concern.


Day 2: 2025-09-01

CATEGORY 2

WHAT
No risk of flooding is expected on day 2 as well. Tide levels are again projected to be in the upper 16-ft range, but conditions are stable and barometric pressure is comfortably above severe-weather levels.

WHEN
Peak tides will occur late morning into midday; however, no flooding is anticipated during these hours.

IMPACTS
No significant coastal impacts. Low-lying areas should remain clear. No property damage or road closures expected.

ADDITIONAL DETAILS...

– The highest tide coincides with barometric pressures above 1003 hPa in the early morning and near 1008 hPa later in the evening.
– NOAA’s official flood likelihood is listed as 0.0%.
– Historically, Category 4 or 5 storms have required much higher tides (near or above 20 ft) and/or substantially lower barometric pressure. Neither factor is present on 09/01.


Day 3: 2025-09-02

CATEGORY 2

WHAT
Although day 3 brings slightly higher tides reaching around 18 ft, there is still no significant flood threat according to NOAA’s analysis, which remains at 0.0% flood likelihood. Barometric pressure remains above 1004 hPa, reducing the chance of widespread coastal flooding.

WHEN
The highest tides occur around mid-afternoon. No inundation is expected.

IMPACTS
Even with these higher tide levels, impacts remain minimal. No major issues are anticipated along the shoreline, and property damage from flooding is unlikely.

ADDITIONAL DETAILS...

– Compared with past Category 3 events that also had tide heights in the 17–18 ft range, NOAA is not indicating flood conditions here.
– Winds are moderate at 5–10 mph, generally from the north/northwest, not pushing significant water onshore.
– Barometric pressure remains far above the historical low thresholds (~992 hPa) that typically contribute to coastal flooding.


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.
