Flood Watch

Redondo Beach, WA

Day 1: 2025-04-11

CATEGORY 2

WHAT
Tides approach moderate levels (reaching around 18.8 ft), but barometric pressure remains well above historical flood-trigger thresholds (near 1000.9 hPa). NOAA guidance indicates a 0% flood likelihood, so no coastal flooding is expected.

WHEN
Highest tide near 03:54 AM local time; however, the potential for flooding is minimal throughout the day.

IMPACTS
No flooding anticipated. Normal tidal fluctuations may briefly affect very low-lying areas, but no damage or closures are expected.

ADDITIONAL DETAILS...

• Tides, although relatively high, remain below the levels observed during notable flood events (19.25–22+ ft).
• Barometric pressure is not near the critical low range (<992.8 hPa) that has historically contributed to flooding.
• Winds are light to moderate, predominantly NW/NNW, offering minimal onshore push of water.
• NOAA’s Flood Likelihood is 0%, further confirming limited flood potential.


Day 2: 2025-04-12

CATEGORY 2

WHAT
Tides again reach moderate heights (peaking near 18.7 ft), but barometric pressure, though slightly lower (down to about 999.8 hPa), still remains above the critical threshold for flooding. NOAA continues to forecast a 0% flood likelihood.

WHEN
Early morning and late afternoon high tides (around 04:12 AM and 05:00 PM) will be the highest points, but no flooding concerns are indicated.

IMPACTS
No flood impacts are expected. Coastal areas should experience normal tidal variation.

ADDITIONAL DETAILS...

• Pressures around 999.8 hPa are not low enough to significantly exacerbate high tide heights.
• Compared with historical Category 3 or 4 events, both the tide height (under ~19 ft) and barometric pressure (well above 992.8 hPa) remain outside of typical flood-risk ranges.
• NOAA’s data show no increase in likelihood for minor flooding or tidal overflow.


Day 3: 2025-04-13

CATEGORY 2

WHAT
High tides continue in the 18 ft range, and barometric pressure remains stable to higher (1005–1006 hPa). NOAA still indicates no flood risk.

WHEN
Morning and evening high tides (peaking around 04:30 AM and later in the afternoon) do not pose a flood threat.

IMPACTS
No known impacts. Normal tidal conditions persist, with no flooding anticipated in coastal or low-lying areas.

ADDITIONAL DETAILS...

• Tide heights remain below significant flood levels noted in past Category 3+ events.
• Pressure readings are relatively high, reducing the likelihood of storm surge.
• Winds forecast from the NW/NNE are moderate and not conducive to piling water inland.
• NOAA’s Flood Likelihood remains at 0.0%, confirming minimal 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 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.
