Flood Watch

Redondo Beach, WA

Day 1: 2025-04-27

CATEGORY 2

WHAT
While tides will reach notable heights (near 19.9 ft), barometric pressures remain above the historically significant low-pressure threshold (<992.8 hPa), and NOAA indicates a very low likelihood of flooding. Consequently, no flooding is expected.

WHEN
Highest tides occur during the early morning hours (around 03:00–04:00) and late afternoon (around 17:00–18:00 PDT).

IMPACTS
No flood-related impacts are anticipated for this period. Normal daily activities can proceed without concern for tidal inundation or coastal flooding.

ADDITIONAL DETAILS...

Tide levels near 19.9 ft are below the typical 21 ft benchmark for coastal flooding risk when paired with higher wind and very low pressures. Current pressures (1010–1015 hPa range) and light to moderate winds do not align with historical flood triggers. NOAA’s Flood Likelihood is 0.0% for this day, matching well with the absence of any significant flood indicators.


Day 2: 2025-04-28

CATEGORY 2

WHAT
Tides again approach high levels (close to 19.9 ft), but barometric pressure (~996 hPa at peak tide) remains slightly above critical flood-trigger thresholds, and NOAA continues to show no expected flood conditions.

WHEN
Primary high-tide windows fall in the early morning (03:00–04:00) and early evening (around 18:00 PDT).

IMPACTS
No notable coastal flooding or property impacts anticipated.

ADDITIONAL DETAILS...

Although the barometric pressure is lower on this day than Day 1, it is still not below 992.8 hPa, making significant coastal flooding unlikely given tide heights remain under the 21 ft threshold. Winds are moderate and mostly from the south, not from the stronger onshore directions that have historically exacerbated flooding.


Day 3: 2025-04-29

CATEGORY 2

WHAT
Slightly higher tides (up to ~19.95 ft) and somewhat lower barometric pressures (~993.9 hPa at peak) are forecast, but both remain outside the critical range needed to produce coastal flooding.

WHEN
Highest tide occurs late in the day (near 19:00–20:00 PDT).

IMPACTS
With tides still below 21 ft and pressures only marginally above severe-event thresholds, no flood impacts are expected.

ADDITIONAL DETAILS...

Even with the lower pressure, historical comparisons show major flooding typically requires pressures significantly below 992.8 hPa combined with tides over 21 ft. NOAA projects a mere 0.1% flood likelihood, consistent with minimal or no flood risk. Winds remain light to moderate and do not suggest a significant onshore push that would compound tidal levels.


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.
