Flood Watch

Redondo Beach, WA

Day 1: 2025-03-30

CATEGORY 2

WHAT
No immediate flood risk is expected. While tidal heights around the early morning high tide (near 20 ft) are relatively high, the barometric pressure (approximately 1014.5 hPa) remains well above critical low-pressure levels, and NOAA’s flood likelihood sits at a low 0.9%.

WHEN
Highest tidal levels will occur around 04:54 AM and again near late afternoon.

IMPACTS
No substantial coastal flooding or property damage is anticipated. Any minor water buildup along shorelines should not pose a significant risk.

ADDITIONAL DETAILS...

• Tidal heights near 20 ft can draw attention, but historically, far lower barometric pressures (e.g., below 1002 hPa) and higher NOAA likelihoods have been associated with flooding events.
• Winds are relatively light and from the E/SE, which typically does not push seawater onshore as strongly as a W/NW wind might.
• Compared with past moderate flood events (e.g., Category 4), the forecast barometric pressure is much higher, and NOAA’s stated flood probability remains very low.


Day 2: 2025-03-31

CATEGORY 2

WHAT
No flood risk is indicated. While another relatively high tide occurs near the morning hours (close to 20 ft), the barometric pressure around 1010 hPa is not low enough to raise concern, and NOAA’s flood likelihood is only 0.5%.

WHEN
Peak tidal levels around 05:24 AM and later in the early evening.

IMPACTS
Little to no impact on coastal areas is expected. Low-lying regions are unlikely to see any notable inundation or road closures.

ADDITIONAL DETAILS...

• Barometric pressure, though slightly lower than Day 1, remains well above typical storm-trigger levels (below ~992–1002 hPa).
• Winds remain moderate and are not oriented in a direction (W/NW) known to exacerbate high tides in this region.
• Historical Category 3 and 4 events often included more adverse wind conditions or notably lower barometric pressures, plus higher NOAA flood likelihood percentages.


Day 3: 2025-04-01

CATEGORY 2

WHAT
No risk of flooding. Even though high tide will again reach near 19–20 ft in the early morning and evening, the barometric pressure around 1012.7 hPa does not suggest significant storm influence, and NOAA’s likelihood stands at 0.0%.

WHEN
Highest tide levels near 06:00 AM and 19:54 PM.

IMPACTS
Coastal roads and low-lying areas should remain clear, with minimal to no water incursion.

ADDITIONAL DETAILS...

• Compared to past moderate to severe flood events, these tides coincide with higher barometric pressures and minimal onshore wind influence.
• NOAA flood likelihood is at 0.0% — considerably below threshold levels that have historically indicated even minor inundation.


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.
