Flood Watch

Redondo Beach, WA

Day 1: 2025-09-01

CATEGORY 2

WHAT
No risk of coastal flooding is expected. Tides reach around 17.49 ft in the early afternoon, but NOAA projects no flood likelihood.

WHEN
Highest tide occurs roughly between 1:00 PM and 3:00 PM PDT.

IMPACTS
No significant impacts anticipated. Low-lying areas and shorelines will remain largely unaffected.

ADDITIONAL DETAILS...

• Barometric pressure readings (around 1002.5–1008.16 hPa) remain well above the low-pressure thresholds typical of past flooding.
• Historical Category 3 events with similar tide heights (e.g., 17.46 ft on 12/27/2023) also featured higher NOAA flood likelihood; the current NOAA forecast is 0.0%.
• Winds are light to moderate and do not align with the stronger onshore directions seen in previous flood events.


Day 2: 2025-09-02

CATEGORY 2

WHAT
No risk of flooding is expected. Tides peak near 17.99 ft, but barometric pressure remains moderate, and NOAA indicates 0.0% flood likelihood.

WHEN
Peak water levels around mid-afternoon, approximately 2:00 PM to 4:00 PM PDT.

IMPACTS
No flooding impacts are anticipated. Roads, parks, and low-lying coastal areas should remain unaffected.

ADDITIONAL DETAILS...

• The highest tide of about 17.99 ft is below the thresholds historically linked to moderate or severe flooding.
• Barometric pressure near 1006.63 hPa is above the critical low range (<992.8 hPa).
• Comparisons with Category 4 or 5 historical events show significantly higher tides (20 ft+), typically combined with much lower pressure.


Day 3: 2025-09-03

CATEGORY 2

WHAT
No risk of flooding. Maximum tides may reach around 18.3 ft, but pressure remains relatively high, and NOAA forecasts no flood conditions.

WHEN
Highest tidal levels are expected from about 2:00 PM to 4:00 PM PDT.

IMPACTS
No notable impacts to infrastructure or roadways. Conditions expected to remain safe near shore areas.

ADDITIONAL DETAILS...

• Although the tide is slightly higher (about 18.3 ft) than Days 1–2, barometric pressure near 1001.74 hPa is still above historically low-flood thresholds.
• Past Category 3–5 floods typically involved tide heights well over 20 ft, especially paired with lower pressure and higher flood likelihood from NOAA.
• NOAA’s forecast for 2025-09-03 remains at 0.0% flood likelihood, indicating 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.
