Flood Watch

Redondo Beach, WA

Day 1: 2025-09-16

CATEGORY 2

WHAT
No risk of flooding is expected. Although tidal levels could reach around 18.8 ft by early afternoon, the barometric pressure remains relatively stable (approx. 1009–1010 hPa), and NOAA’s flood likelihood analysis for this day is 0.0%.

WHEN
Highest tides will occur around midday into the early afternoon on 09/16, with minimal indications of coastal flooding.

IMPACTS
No significant impacts anticipated. Coastal areas should remain unaffected, with no expected inundation on roadways or low-lying properties.

ADDITIONAL DETAILS...

• Tides peak near 18.7 ft, below thresholds observed in historical Category 3 or higher events.
• Barometric pressure is not unusually low, decreasing concern for major tidal surges.
• NOAA’s official outlook provides a low flood likelihood and supports a “no-risk” conclusion.


Day 2: 2025-09-17

CATEGORY 2

WHAT
No risk of flooding is anticipated. Projected tide heights may approach 19.1 ft in the mid-afternoon, but the barometric pressure around 1019 hPa remains high, mitigating flood potential.

WHEN
Primary high tide window focuses around 3:00 PM on 09/17, but little to no flooding is expected due to favorable weather patterns.

IMPACTS
No coastal flooding impacts are expected. Normal beach and shoreline conditions should prevail, with negligible disturbance to local infrastructure or travel.

ADDITIONAL DETAILS...

• Despite moderate tidal heights, the stable and relatively high pressure greatly reduces coastal flood chances.
• Historically, Category 3 flood events typically involve lower barometric pressure or higher tide levels.
• NOAA reports 0.0% flood likelihood for this date, indicating confidence in minimal risk.


Day 3: 2025-09-18

CATEGORY 2

WHAT
No risk of flooding is expected. Tides could peak near 19.2 ft in the afternoon, but the barometric pressure (approx. 1015–1016 hPa) remains sufficiently high, and NOAA data continues to indicate low flood potential.

WHEN
Highest tides occur roughly mid-afternoon on 09/18, with no flood impacts anticipated for shoreline or low-lying zones.

IMPACTS
No impacts from flooding are expected. Normal tidal variations should not pose hazards to property or transportation routes.

ADDITIONAL DETAILS...

• Peak tides near 19.2 ft remain under historical flood-triggering thresholds.
• No supporting factors (e.g., low pressure, onshore gales) appear significant enough to raise flood concerns.
• NOAA again projects 0.0% flood likelihood.


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.
