Flood Watch

Redondo Beach, WA


Day 1: 2025-08-17

CATEGORY 2

WHAT
No notable flooding is expected. Tides could reach around 18 ft in the late evening, but barometric pressure readings remain relatively high (near 1013 hPa), and NOAA’s flood likelihood remains at 0%.

WHEN
Highest tide levels expected late in the evening, roughly 8:00 PM - 11:00 PM.

IMPACTS
• Minimal to no flooding impacts anticipated.
• No significant property damage or travel issues expected.

ADDITIONAL DETAILS...

Historical Category 3 events typically showed either lower barometric pressure (below ~1006 hPa) or a higher NOAA flood likelihood. In this case, although tides approach 18 ft, the barometric pressure is not sufficiently low to suggest a developing flood scenario. NOAA reports a 0% flood likelihood, reinforcing that conditions will likely remain safe.


Day 2: 2025-08-18

CATEGORY 2

WHAT
No risk of flooding. Even though the barometric pressure dips closer to 1002 hPa during the late high tide, it is still well above the historically critical threshold of ~992.8 hPa.

WHEN
Early morning (around 8:48 AM) and late-night (near 11:48 PM) high tides.

IMPACTS
• No property damage or inundation concerns are expected.
• Shorelines and low-lying roads should remain clear of significant water intrusion.

ADDITIONAL DETAILS...

Past Category 4 or 5 events involved significantly lower pressures and tides often exceeding 20 ft, sometimes with confirmatory higher NOAA flood likelihood percentages. Here, the tide heights and pressure levels do not align with those more serious flood scenarios, and NOAA again indicates a 0% flooding chance.


Day 3: 2025-08-19

CATEGORY 2

WHAT
Still no indication of flood threats. Although the barometric pressure drops to around 1000 hPa, tides remain below major flood thresholds, and NOAA’s forecast continues to report 0% likelihood of flooding.

WHEN
Two higher-tide periods: mid-morning (around 9:54 AM) and mid-afternoon (around 3:36 PM).

IMPACTS
• No significant impacts expected.
• Minor ponding along very low-lying areas at the shoreline would be possible but not forecast to cause actual flooding.

ADDITIONAL DETAILS...

Comparisons to historical flood events (e.g., Category 3 or above) show those episodes typically featured either markedly lower barometric pressure or NOAA flood-likelihood percentages well above zero. With consistently higher pressures around 1000 hPa and NOAA forecasting no flood potential, this day also falls solidly into a no-flood-risk scenario.


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.
