Flood Watch

Redondo Beach, WA

Day 1: 2025-09-13

CATEGORY 2

WHAT
No substantive risk of coastal flooding is expected. The highest tide is projected near 20:12 PDT (approximately 18.6 ft), but the barometric pressure is forecast around 996.66 hPa—slightly lower than typical but still above the critical low-pressure threshold. NOAA’s Flood Likelihood is 0.0%, indicating minimal concern.

WHEN
Highest tide around early evening, centering near 20:12 PDT.

IMPACTS
Because tides remain below more serious flood heights and pressures are not extremely low, no flooding of roads or property is expected.

ADDITIONAL DETAILS...

• Historical Comparisons: Past Category 3 events involved higher or comparable tide levels accompanied by moderate to high flood likelihood forecasts (e.g., ~17–20 ft with NOAA likelihoods above 0%). Here, NOAA rates the day’s flood likelihood at 0%.
• Wind Influence: Winds are generally from S/SE, not from westerly or northwesterly directions that typically exacerbate coastal flooding along Redondo Beach.


Day 2: 2025-09-14

CATEGORY 2

WHAT
Again, no substantive risk of coastal flooding is expected. While barometric pressure briefly dips to around 995.0 hPa at an early-morning tide, that tide height remains relatively low (~9.9 ft). Later higher tides (~17.9 ft) coincide with a higher pressure near 998.17 hPa. NOAA’s Flood Likelihood is 0.0%.

WHEN
Highest observed tide mid to late morning into early afternoon; however, lower barometric pressure periods do not align with that peak tide.

IMPACTS
No anticipated property or roadway flooding impacts; local areas should see normal conditions near the waterfront.

ADDITIONAL DETAILS...

• Historical Comparisons: Category 3–4 events typically saw tide heights above 19 ft, with low barometric pressures overlapping peak tide times. That combination is absent here, and NOAA data strongly supports minimal flood risk.
• Wind Influence: Primary wind directions remain southerly, further minimizing onshore push of water.


Day 3: 2025-09-15

CATEGORY 2

WHAT
No noteworthy coastal flooding risk is forecast. The maximum tide (~17 ft) occurs late in the evening at ~22:30 PDT under a relatively higher barometric pressure near 1008.4 hPa. NOAA’s Flood Likelihood continues at 0.0%.

WHEN
Highest tide late evening around 22:30 PDT.

IMPACTS
No significant inundation of low-lying coastal areas or roads is anticipated.

ADDITIONAL DETAILS...

• Historical Comparisons: Tide levels remain below thresholds typically associated with more serious coastal flooding (19+ ft). Barometric pressure is not near the lower range (<993 hPa) that has historically accompanied damaging flood events.
• General Outlook: Trends show stable weather with no major pattern shift, consistent with NOAA’s “Low” flood likelihood rating.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

You should monitor later forecasts and be alert for possible Flood Warnings. Although no flooding is anticipated at this time, those living in areas prone to flooding should remain prepared to act if conditions change.

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.
