Flood Watch

Redondo Beach, WA

Day 1: 2025-09-09

CATEGORY 2

WHAT
No flooding is expected. While the high tide will reach approximately 19.8 ft, keeping a watchful eye on local conditions is prudent. Barometric pressure remains around 1013 hPa, which is higher than critical low-pressure levels historically linked to coastal flooding.

WHEN
The highest tide occurs around 5:48 PM local time.

IMPACTS
No significant impacts are anticipated. Normal coastal conditions should prevail around the high tide period, and NOAA’s flood likelihood forecast indicates 0.0% chance of flooding.

ADDITIONAL DETAILS...

Historical comparisons show that Category 3 or higher flood events (e.g., 01/06/2025 with a 20.68 ft tide) involved similarly high tides but were accompanied by higher or comparable pressure, or there was a notably low pressure in Category 4+ events. Here, the pressure is neither critically low nor are onshore winds significant, which aligns with NOAA’s low risk assessment.


Day 2: 2025-09-10

CATEGORY 2

WHAT
No flood risk is expected. The high tide is forecast near 19.8 ft again, but barometric pressure is around 1016 hPa, indicating stable conditions with minimal coastal flooding potential.

WHEN
The primary high tide occurs near 6:18 PM local time.

IMPACTS
No notable coastal flooding impacts. Roads, shorelines, and low-lying areas are unlikely to be affected under these conditions.

ADDITIONAL DETAILS...

Even though the tide height is comparable to some historical moderate events, the higher atmospheric pressure and calm wind directions reduce the likelihood of flooding. NOAA’s forecast remains at 0.0% flood likelihood, further supporting a Category 2 (no flooding) designation.


2025-09-11

CATEGORY 2

WHAT
No flooding is expected. The highest tide will reach about 19.6 ft, with a barometric pressure near 1009 hPa—still well above critically low levels that historically correlate with flood conditions.

WHEN
The highest tide is around 6:48 PM local time.

IMPACTS
No direct impacts are anticipated. Similar to the previous days, NOAA’s outlook indicates no flood threat, so routine activities in coastal areas should be unaffected.

ADDITIONAL DETAILS...

While the pressure is slightly lower than on Day 2, it remains significantly higher than the 992-1002 hPa range often seen with more serious coastal flooding events. The absence of strong onshore winds and NOAA’s maintained 0.0% flood likelihood both confirm minimal flood 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 if conditions unexpectedly change. For final decisions on protective measures, consult local authorities and official emergency guidance.

CATEGORY KEY

• Categories 1-2: No risk of flooding.
• Category 3: Close to a flood event and worth monitoring.
