Flood Watch

Redondo Beach, WA

Day 1: 2025-10-08

CATEGORY 2

WHAT
No coastal flooding is anticipated. High tide is forecast around 16:54 PDT, reaching roughly 19.84 feet; however, barometric pressure is significantly higher (approximately 1029 hPa), and NOAA’s flood likelihood projection is 0%.

WHEN
Primary high-tide timeframe of note is mid-to-late afternoon (around 16:00–17:00 PDT).

IMPACTS
No flooding impacts are expected. Low-lying areas and shorelines should remain unaffected.

ADDITIONAL DETAILS...

• Historical Category 3 or higher events typically feature a lower barometric pressure (around or below 1002 hPa) combined with higher tides exceeding 20 feet.
• Today’s high barometric pressure reading indicates stable atmospheric conditions, significantly reducing any flood risk.
• NOAA’s data for 2025-10-08 shows a 0.0% flood likelihood, reinforcing a very low flood potential.


Day 2: 2025-10-09

CATEGORY 2

WHAT
No flooding is expected. Peak tide approaches ~19.66 feet in the late afternoon (around 17:24 PDT), coupled with a high barometric pressure near 1026 hPa, which diminishes flood potential.

WHEN
Highest tide forecast occurs late afternoon (roughly 17:00–17:30 PDT).

IMPACTS
Little to no impact. Low-lying roads and basins should experience normal conditions with minimal water encroachment.

ADDITIONAL DETAILS...

• Barometric pressure remains substantially above the threshold typically associated with significant coastal flooding (below ~1002 hPa).
• Tides do not exceed ~20 feet, and NOAA’s official flood likelihood for 2025-10-09 is 0.0%.
• Compared to past Category 3 and 4 events (which showed much lower pressures), conditions favor no flood development.


Day 3: 2025-10-10

CATEGORY 2

WHAT
No flood risk anticipated. The highest tide will peak around 07:30 PDT at approximately 19.56 feet, with pressure around 1019 hPa—still well above historically low-pressure events that contributed to coastal flooding.

WHEN
Morning high tide window near 07:00–08:00 PDT. A second elevated tide occurs late in the evening (around 22:42 PDT), but pressure and tide levels remain unlikely to cause flooding.

IMPACTS
No notable flood impacts expected in low-lying or shoreline areas.

ADDITIONAL DETAILS...

• Even though the barometric pressure (about 1019 hPa) is lower than Days 1–2, it is still well above the range generally associated with severe coastal flooding.
• NOAA reports a 0.0% flood likelihood for 2025-10-10, confirming minimal risk.
• Historical severe events, such as the Category 5 event on 12/27/2022, involved significantly higher tides (over 22 feet) and much lower pressure (below 978.4 hPa). Current conditions do not approach that threshold.


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.
